Flutter: The Framework For Cross Platform Applications

Flutter: The Framework For Cross Platform Applications

Flutter is an open- source software development tool which enables smooth and easy cross-platform mobile app development. You can make high quality natively collected apps for iOS and Android snappily, without having to write the law for the two apps independently. All you need is one codebase for both platforms.

Last time, Tim Sneath, product director of Flutter blazed an adding use of Flutter with further than 2 million inventors using the toolkit since its release in 2018. The spring update also reveals that it’s seeing a supplement in not just consumer apps but also enterprise app development.

In this composition we’re going to introduce this inventor-friendly app development language. We ’ll explain what Flutter is, and we will brief out its advantages and disadvantages.

What’s Flutter?

Back in the days of ideal C/ Swift and Java/ Kotlin as primary languages for mobile development, erecting apps was precious. You had to make two separate apps, which obviously meant doing the work doubly.

To break this problem, several fabrics have been constructed for the creation of mongrel( cross-platform) apps in HTML5 and Javascript. Among the cross-platform toolkits, including Phonegap, Xamarin, Reply Native, and more, the Flutter frame has snappily come decreasingly popular among inventors, enterprises, entrepreneurs and druggies.

Flutter is a movable UI toolkit for erecting native- suchlike apps across mobile, web and desktop, from a single codebase. It uses the programming language Dart and incorporates Material Design and Cupertino contraptions. Flutter inventors can produce spectacular UI that looks and feels native. It behaves naturally on any platform, indeed though you ’re using one codebase.

Flutter is the only frame with a mobile SDK that provides a responsive style without using a Javascript ground, thereby reaching a position of performance that rivals its kinsman and direct contender Reply Native. It fluently integrates with the different platforms similar as Android, IOS and Linux, MAC, Windows and Google Fuchsia operations.

What’s Flutter used for?

Flutter is one of the stylish results to develop apps for Android and iOS, without having to write in a different codebase for each platform. The smartphone performances of these apps serve as true, native apps on Apple and Android bias and are collected for the separate platform before publication. They don’t need a runtime module or a cybersurfer. Using the same codebase, it’s also possible to produce web apps for cybersurfers as well as native programs for Windows, Linux and macOS.

Google itself uses Flutter for several modules of the Google Assistant and for the stoner interface of the Google Home mecca. Well known e-commerce service providers similar as eBay, Groupon or Alibaba Group use Flutter to give their mobile and web apps an invariant look.

What programming language is Flutter grounded on?

The Flutter SDK is grounded on the Dart programming language, also developed by Google. Its intent is to display classic JavaScript. On a garçon, Dart programs can be run directly, while in the cybersurfer they’re converted to JavaScript using the Dart2js transcompiler.

Apps for Google’s new platform, Fuchsia, are developed directly with Dart. Its structure is analogous to that of well- known object- acquainted programming languages similar as Java orC#.

It’s All contraptions The Flutter principle

Flutter is a contrivance- grounded technology. This means that you can apply object- acquainted programming to any element. One of the benefits of using Flutter is that you can modify or customise contraptions with ease. In addition, it provides UI contraptions that meet crucial web operation design conditions.

Flutter, as an open- source frame, has attracted a broad and active community of inventors since its release. This community constantly publishes usable law exemplifications and supports inventors in creating new, innovative, beautiful cross-platform apps.

Pros and cons of Flutter app development

Every programming language has its advantages and disadvantages. But, in utmost cases, we can say that the advantages of Flutter, compared to analogous technologies, easily outweigh its disadvantages.

Pros of Flutter app development

Flutter has multitudinous advantages over its challengers. These advantages are essential in the programming language and in the set of development tools that allow Flutter to break issues that other languages can not manage with.

1. One codebase for all platforms

Gone are the days of having to write a law for Android and another codebase for iOS bias. Flutter’s law reusability allows you to write just one codebase and use it on not only for mobile Android and iOS but indeed for web, desktop and further. This cuts development time significantly, removes cost and enables you launch your app that much briskly.

2. “ It’s all contraptions ” principle offers innumerous possibilities

Flutter’s custom contraptions are an absolute delight when it comes to creating great illustrations for your app. At the same time, you do n’t have to worry about the UI being biassed.

3. Rich libraries

Flutter uses the Skia Graphics Library which is a fast and mature open- source plates library. It redraws the UI every time a view changes. The result? A quick lading and smooth app experience.

4. Fast testing with hot reload

The hot reload point makes the app development much hastily. With Flutter there’s no need to reload the app to see every single change you make in the law. You can fluently make changes in your app in real time, so you have further occasion to experiment with the law and fix bugs on the go.

Cons of Flutter app development

There are no indefectible technology results, and Flutter is no exception. Flutter’s cons are n’t exactly deal- combers, but there are many reasons why it might not be the ideal toolkit for a specific app.

1. Large train size because of the contraptions

Flutter apps are relatively large and “ heavy ” to start with. They enthral a lot of space and take longer to download or modernise.

2. Complex updating

streamlining programming conditions in operating systems requires streamlining Flutter modules. Since the modules are integrated as fixed rudiments in the program, the ultimate must also be reedited and reinstalled on the bias.

3. Limited set of tools and libraries

Flutter is a relatively new development framework, so in some cases you may not be suitable to get the asked functions in the current library. Flutter will take some time to produce certain tools, expand functionality and develop the community.

Apps developed on Flutter

The fashionability of Flutter app development is constantly growing. Now Flutter is extensively used to produce apps for the likes of Alibaba, Yandex, Airbnb, Uber, eBay and other leading companies. There’s a selection of the top Flutter apps.

Flutter and Reply Native advantages and disadvantages

Pros of Flutter

Hot- reloading Stateful Hot Reloading point reflects changes incontinently without losing the operation state.

Rich- contraptions Provides rich contraptions that follow the guidelines of Cupertino( iOS) and Material Design( Android).

flawless integrationRe-writing law isn’t necessary as it fluently integrates with Java for Android and Swift or Objective C for iOS.

Quick shipping Offers quick replication cycles and saves figure time as testing is needed only for one single codebase.

Codesharing Canons can be written and participated across platforms easier and briskly, which makes it perfect for MVP development.

Cons of Flutter

  • Tools and Plugins Libraries and tools are emotional, yet it’s not as rich as React Native.

stoner interface Vector plates and vitality support have issues in rendering plugins on time.

Operating platform Not compatible to develop apps for tvOS, Android Auto, CarPlay, or watchOS.

  • Updates Can not incontinently push patches and updates into operations without passing through the standard release processes.

Pros of React Native

  • Native picture Uses host platform to natively render APIs without the need for HTML or CSS luxury.
  • Performance Translates the luxury of an operation to mimic authentic UI rudiments and yet maintain high performance.
  • Ecosystem Leverages rich ecosystem and UI libraries to automatically re-render app appearance with each state change.
  • Debugging Provides availability to intelligent debugging tools and error reporting.
  • Hot- reloading Allows hot reloading to add new canons directly into a live operation.

Cons of React Native

  • stoner Interface Native picture of APIs may not support certain native UI rudiments, which may make the UI look a little off.
  • Tools and Plugins Third- party libraries that can be used for better perpetration may frequently turn out to be outdated.
  • Performance Doesn’t support threading andmulti-processing, performing in slow performance.
  • Debugging Chrome debugger might be inconvenient to edit, check canons, and UI rudiments duly.

Performance comparison

The difference between the performances of React Native and Flutter is relatively debatable. The separate communities of both Flutter and RN are a bit divided over the content ‘ performance ’ as everything about them sounds good in terms of dexterity and speed. still, RN has also entered some review for its performance due to the involvement of native modules and third- party libraries. That said, let’s dive in a bit more in detail to learn about the Flutters. Reply Native performance difference. For this, we will consider a simple “ hello world ” app with one simple image erected with both Flutter and RN.

How does Flutter stand out in terms of performance?

Flutter operation is more performant as compared to React Native. It doesn’t bear a ground to communicate between the native modules due to the dereliction of native factors. The performance test indicated that the “ hello world ” app always performed at 60 FPS, and the time taken to render each frame doesn’t take longer than 16 milliseconds. The number of frames that got dropped were smaller. As mentioned, Flutter uses the Skia plates library, which allows the UI to be redrawn each time with each change in the operation view. No wonder, Flutter can perform efficiently indeed at 60 FPS.

Operation armature

Flutter & RN both offer several architectural advantages to operation inventors. Let’s talk about them in detail.

What kind of armature does Flutter support?

Flutter’s armature is concentrated. The scale of a simple operation erected on this frame starts with top- position root function or, in other words, platform-specific contraptions. It’s followed by introductory contraptions that interact with the platform and rendering layers. Just beyond the picture subcaste exists the vitality gestures that transfer API calls to the foundation of the operation. It’s also known as Scaffold that’s run by a C/ C machine and a platform-specific embedded.However, you can consider enforcing Flutter BLoC, If you want to separate the donation subcaste from business sense. This armature makes it easier for endured as well as inferior Flutter inventors to produce complex operations with small and simple factors.

What kind of armature does Reply Native support?

Under the hood, Reply Native possesses a ground between the Native thread and JavaScript thread. As per this functionality, the JavaScript law communicates with the platform and the Native API. In iOS, Reply Native uses JavaScriptCore independently to run all canons, whereas it bundles the JavaScriptCore within the operation in Android. Whilst this might increase the native functionality, it also increases the app size, performing in performance issues or device pause.

felicity for erecting complex apps- Flutter vs React Native

Both Flutter and RN offer sanctioned documents, guidelines, open- sourced systems, and third- party libraries and plugins to support inventors throughout the development process. Still, if we compare Flutter and Reply Native in terms of feasibility, we can conclude that the former is more favoured to make complex apps.

Is Flutter suitable for erecting complex apps?

At the time of writing this composition, Flutter isn’t suitable to handle more complex systems. Still, startups can still use flutter as a good result for erecting minimum Valuable Product( MVP).

It can be assumed as an excellent option to make briskly prototypes when you’re most likely to experiment with them and cut costs to see your idea in action. The idea then’s to make two different prototypes( iOS and Android) with Flutter and dissect the results in the request. Later, you can invest further and take your idea from simpler to complex bones .

Is Reply Native suitable for erecting complex apps?

Yes, you can work Reply Native to make complex native apps. But it’s important to note that will be likely to be possible only when you involve native app development along with React Native. At that stage, your operation is more likely to be cold-blooded than cross-platform. The entire process of erecting complex apps with Reply Native doesn’t only involve Javascript but the application of native development chops.

Ease of Testing

Maintaining the smooth functioning of law with minimum time and trouble is one of the primary pretensions of development. In the below section, let’s take a look at how easier it’s to apply testing in both Flutter and Reply Native apps.

How easier is it to test a Flutter app?

Flutter, on the other hand, offers expansive support for automated testing since it functions with an outrage. Not only does it offer a myriad number of testing features to test apps at the unit, contrivance, and integration position, but also boasts of detailed attestation related to it. What’s more, Flutter provides robust attestation to make and release Android and iOS apps on the Play Store and App Store independently. In addition, it has its deployment process proved officially as well.

How easier is it to test a React Native app?

Reply Native credits of no sanctioned support for UI position testing and Integration testing. Likewise, there are only a few unit- position testing fabrics available to test RN apps. No sanctioned support means inventors have to calculate on third- party tools like Appium and Detox and unearth bugs with the help of them.

Also, It’s still counting on third- party libraries for figure and release robotization. Shortly put, the entire frame does n’t offer any automated way to emplace the iOS apps to the App Store. Rather, RN suggests inventors define the homemade process of planting the app through Xcode.

Community around Flutter and Reply Native

Really, both Flutter and Reply Native have evolved over these times with every technological update. And, guess what? With every incremental interpretation and technological update, the interest and appreciation of the inventor community have increased. Let’s see how effects are between both fabrics when it comes to community engagement.

How big is the community around Flutter?

Ever since its launch in 2017, the Flutter community is gaining a laddie bit more traction than Reply Native. still, the number of professional contributors are 662 only, which is much lower than Reply Native. Yet, the count of live systems being diverged by the community together is around13.7 k, where anybody can seek help in development. Some popular platforms for connecting with the global community of Flutter

  • Slack
  • Disharmony
  • Gitter
  • Reddit
  • Flutterday
  • Mound Overflow

How big is the community around Reply Native?

Since the launch of React Native in 2015, its community has been growing, and the number of contributors to the frame on GitHub is the evidence of that. presently, there are further than 207 professional inventors who laboriously partake in their guests . Indeed a neophyte can fluently seek help in developing React Native operations. In fact, there are over19.8 k live systems where inventors come together to resolve issues. Some of the common platforms where you can find other React Native inventors, systems, conferences, and live events are

  • Meet Up
  • Slack
  • Disharmony
  • Telegram
  • Reddit
  • Mound Overflow

Modularity comparison in Flutter vs React Native

The Modularity aspect of a frame indicates the capability or the extent to which it allows different people with different specialised chops and gests to work under one design. For example, a big operation with an incoherent law structure may take longer to make. Let’s check whether Flutter and Reply Native compare in terms of Modularity.

Does Flutter support modularity?

Flutter offers better availability for platoon diversity as well as the division of design canons into different modules with its cantina package system. Your platoon can fluently construct different modules with the draw- in capability and add or change a codebase. At the Droidcon NYC conference 2019, BMW engineers mentioned how they enabled multiple brigades with different skill sets to painlessly work with Flutter.

Does React Native support modularity?

Compared to Flutter, Reply Native may offer lower modularity support. Android, iOS, and Reactjs inventors might find it hard to relate with each other. Without moxie, different brigades may have issues with law fragmentation in React Native. Still, Reply Native offers the possibility to combine simple native rudiments of different zilches platforms for different inventors to work together to some extent.

law Maintainability

Reply Native indeed has one of the biggest communities and sanctioned support, yet there are problems that you might face while maintaining the language for your operation. In fact, it’s more accessible to maintain Flutter than Reply Native.

How accessible is it to maintain law in Flutter apps?

In discrepancy, maintaining a Flutter operation is easy. The simplicity of law helps inventors spot issues, source external tools, and support third- party libraries. Likewise, the stateful Hot Reloading point incontinently resolves issues at hand. The time taken for releasing quality updates and making immediate changes in the operation are considered to be better than the hot reloading capacity of React Native.

How accessible is it to maintain law in React Native apps?

In React Native, upgrading and remedying the law is a pain, maybe. When you chopstick the law to suit your operation, it interferes with the frame’s sense thereby decelerating down the development process. In addition to that, the utmost of the native factors might have a third- party library reliance. frequently these libraries are outdated and can not be maintained duly due to the issues that come on with it by dereliction.

Comparing stoner experience in Flutter vs React Native

Stoner experience is one vital element in choosing the right mobile development frame for your design. It aims to offer intuitive guests that keep druggies stick to the product or brand. Also, a meaningful stoner experience allows you to define client peregrinations on your website that are most conducive to business success.

Flutter’s capability to give the stylish stoner experience

Flutter offers a rich stoner experience with simplified tools, rudiments, and indeed customised contraptions. The generational scrap collection point is also a part of Dart which helps in creating UI frames for object canons that may be temporary. This point of Dart allocates objects within a single pointer bump that avoids UI clutter, junk, and shutter of vitality pause during the development process.

Reply Native’s capability to give the stylish stoner experience

Android’s Material Design and Style Design in iOS are transubstantiation by the day, and it’s tough for React Native to keep up with the constant change in the conditions of native platforms. Also, ready- made React Native UI accoutrements similar as React Virgin, Shoutem, and Ant Design make it indeed more delicate to produce harmonious designs across platforms. Still, some precious factors like ScrollView fixed title, Modal factors, exertion pointers, Snap carousels, and Pagination factors help greatly in perfecting the UX across multi-platform.

Operation size

The selection of a mobile frame can have a large impact on the size of the operation law. For a large design, the operation size should dominate the frame size. lower size is always further in this case. Let’s chart out the difference between Flutter and Reply Native in terms of operation size.

Size of the operation in Flutter

The size of a simple welcome world app created in Flutter was7.5 MB. With Flutter, the size of this app is told by the Virtual Machine of Dart and the C/ C machine. still, Flutter can tone- contain all canons and means to avoid size enterprises. Also, operation of a special label like – split- debug- word helps reduce the law size.

Size of the operation in React Native

The original size of the Hello World app with Reply Native was 7 MB and when native dependences were added, the size increased up to 13.4 MB. Reply Native can reiterate operations briskly and at a minimum size, better than Flutter.

In addition to that, enabling Proguard and using enableSeperateBuildPerCPUArchitecture element will reduce the size in large by bus- generating split builds for all native and external libraries.

Learning wind

Both Flutter and Reply Native retain different literacy angles by which you can make some rough computations of the time taken to make a simple to- do operation from scrape. So how doable is it to learn Flutter and Reply Native? Let’s explore in the following section.

How good is the literacy wind of Flutter for inventors?

On the other hand, Flutter isn’t that hard to learn. Writing law with Dart might be a little unusual but that’s what makes developing with Flutter easier. To learn this frame, all neophyte needs is some introductory know- style of native Android or iOS development. What’s more, inventors have reported that attestation in Flutter is a lot smoother than Reply Native.

How good is the literacy wind of React Native for inventors?

literacy Reply Native is vastly simple for those who have erected operations using JavaScript. But, web development is different from mobile app development which is why mobile inventors find it fairly delicate to learn and apply the frame. Over time, Reply Native has released colorful libraries, expansive documents, and tutorials that ameliorate the literacy wind.

Comparison for platoon size in Flutter vs React Native

Irrespective of the advantages and disadvantages of Flutter and Reply Native, it’s important to identify the platoon size before you begin the development. This will help you plan and make a decision grounded on the cost that might be incurred in sourcing or hiring inventors who might be a neophyte or someone who’s formerly well- clues with the frame of your choice.

How big should be the needed platoon- size for Flutter?

It’s taken no further than 5 inventors for big players like Alibaba, BMW, Watermania, PostMuse among others to make their operations on Flutter. The frame’s literacy wind is easy. Not only does it allow inventors to write canons painlessly but it’s also easier for new inventors to understand those cannons. Since the training cost for Flutter and Dart is provident, indeed a neophyte inventor can be trained fluently and you don’t have to hire multiple educated inventors.

How big should be the needed platoon- size for Reply Native?

To make an operation with Reply Native, you ’ll need about 5 to 10 inventors. This platoon can be a blend of gifts with at least 2 Reply Native experts to guide the platoon through the development lifecycle. Also, since law conservation of different platforms is pivotal for the success of a React Native operation, it’s recommended that you team up with inventors who have a different specialised background.


Flutter does a great job at creating multiple duplications and MVP operations. Reply Native is a good frame to make simple native and cross-platform operations. To help you further, we ’ve created a roster that should help you choose which bone of these technologies must make it to your tech mound.

Flutter Advantages and Disadvantages for Mobile App Developers

Flutter Advantages and Disadvantages for Mobile App Developers

Google I/O 2019 focused heavily on Flutter, announcing an almost overwhelming quantity of news regarding this technology. Here are a few examples:

  • Google has released a web preview version of Flutter. It’s no longer known as Hummingbird; it’s now known as Flutter Web (An example of Flutter Web is New York Times puzzle game)
  • Google released Flutter 1.12 with numerous enhancements (check out the Flutter changelog that documents noteworthy changes)
  • The most recent Flutter release includes functionality for creating Chrome OS applications.
  • Google has launched Dart 2.3, which includes new support for UI-as-code capabilities.

Flutter allows for the rapid and simple building of cross-platform mobile apps. You do not need to create separate iOS and Android apps. All you need is a single codebase to support both platforms.

Furthermore, Flutter:

  • Is open-source and free,
  • Is built on Dart, a quick, object-oriented programming language that is simple to learn in and of itself.
  • It will provide its own widgets, which will be produced using its own high-performance rendering engine. They are quick, attractive, and adaptable.
  • Flutter apps look and feel amazing because of the rich widgets (you can construct your own original app design, but you can also use widely available UI elements that adhere to certain platform rules). Check the post-Top Flutter-Created Apps.
  • Flutter’s architecture is based on today’s popular reactive programming (the same that React has been made from)
  • It’s becoming a strong rival to React Native, as well as native app development. Read the articles: Top innovative mobile app build using Flutter .

What is the point of Flutter? Top 7 Benefits for Mobile App Owners

The following are the most important benefits from the standpoint of an app owner: Flutter accelerates the mobile app development process, lowers app development costs, and assists your team in creating a beautiful app UI with seamless animations. Let’s take a closer look at it. We created the lists below with the help of Paulina Szklarska and Karol Wrótniak, two of our Android Developers who work with Flutter.

Also read : Flutter & its pros and cons ?

  • Faster code creation

Flutter enables faster and more dynamic mobile app development for developers. We can make changes to the code and immediately see the results in the app! This is known as a hot reload, which normally takes (milli)seconds and allows teams to add features, correct errors, and experiment more quickly. It is one of the features of Flutter that every top Flutter app development team adores.

Hot reload is particularly useful in developer-designer collaboration when we want to tweak or experiment with an app’s look and see the results right away. In other words, using Flutter, your designer or tester may collaborate with a developer on the UI, suggesting adjustments – for example, “Put it 2 pixels right” or “Make the animation faster” – and immediately see the results.

  • A single code for two platforms

Developers build a single codebase for your two apps, which span both the Android and iOS platforms. Because it has its own widgets and designs, Flutter does not rely on the platform. This means you have the identical app on two different platforms. However, it is vital to note that if you want to differentiate your apps, it is doable.

  • Fewer tests

It implies less testing if you have the same software for two platforms! The Quality Assurance procedure might be sped up. Because of the shared codebase, developers only need to write automated tests once. Furthermore, because there is just one app to test, Quality Assurance specialists have less work to complete. Of course, if your apps differ in any way, they must be evaluated on both platforms.

  • Apps that run faster

Flutter apps run smoothly and quickly, with no stuttering or clipping while scrolling. Read this article if you want to know why and how it works from a technical standpoint. Also, have a look at this fantastic article in the Flutter documentation that discusses best practises for app speed.

  • Designs that your customers will appreciate

Flutter is designed to make it simple to create your own widgets or modify existing ones. You may browse a catalogue of Flutter widgets here and see examples such as Material Design widgets and Cupertino widgets.

Is there anything negative about Flutter- Let’s dig into that-

  • Libraries and support are impressive, but not as extensive as in native programming.

Google’s support for Flutter is excellent, and there are numerous useful libraries with ready-to-implement capabilities. However, Flutter is still in its early stages, and these libraries may not provide all of the functionality you require. This means that your developers would have to build them themselves, which could take a long time.

  • Help with Continuous Integration

Codemagic, a new CI/CD system for Flutter applications, was announced at Flutter Live 2018.

Bitrise released the full-featured Flutter CI in January 2019.

It’s worth noting that one of our team members, Karol, is constantly working on the Flutters build phase for Bitrise. The most recent edition added the ability to create appbundles for Android releases (read more about it here).
