Pros and Cons of Flutter for Cross-Platform Mobile App Development

For the creation of mobile apps- The two most popular platforms are iOS and Android. For application development, each of these platforms requires distinct sorts of code. Various mobile app development firms have found that separate coding has become an issue, resulting in the usage of cross platform development.


Gone are the days when app developers had to work double time to create an app for a platform. Thanks to multi platform app development frameworks, it is now feasible to create an app with one-time coding.


The finest cross platform app development entails the building of mobile apps that can operate on a variety of systems. Programming is done only once in this sort of development so that the software is compatible with Android, iOS, and Windows. Cross platform development has grown in popularity as a result of its developer-friendly features and tools.


Microsoft's Xamarin, Facebook's React Native, and Adobe's PhoneGap are all popular cross-platform development tools. Each of these programming tools has its own set of features as well as advantages and disadvantages.


Developers are constantly seeking for new and improved ways to make app development more time-saving and efficient. Flutter was born as a result of this continuous technological advancement.


Framework for mobile devices that run on many platforms


What exactly is Flutter?

Google announced Flutter, a software development kit and a fantastic cross-platform app development tool. It is programmed in the Dart language. Flutter was released in 2018 with features that earlier cross-platform programming tools lacked.


Apps created using Flutter may be run on Android, iOS, and Google Fuchsia, another Google app development platform. However, with the debut of Flutter, a dispute between Flutter and React Native has raged among developers.


Flutter is popular among developers because of its efficiency and competence. Before it was released to the public, Google's developers had been hard at work on it. Here are some of the projects they worked on:


More Firebase APIs can be supported

Its unique set of tools

Fixes for bugs

Documentation has been improved.

Encourage the growth of Windows.

Tools for Android Studio and Visual Studio Code that improve engine performance

Different languages are supported. e.g., internationalisation

Developers of various sorts can use it.

Additional elements such as inline movies, charts, and advertisements are available.


What is the purpose of Flutter?


This question has been circulating since Flutter's rise to fame. People want to know which types of development Flutter supports and does not support before opting to build a mobile app with it. If you're working on anything like this, Flutter isn't the way to go.


Instant or Progressive Web Apps — These apps must be tiny, whereas Flutter apps, on the other hand, are larger than native apps.

Apps that require rare native libraries — Flutter is new, and it does not yet contain all of the native libraries in its repository, thus if an app requires an uncommon native library, it can make the process more difficult. Developers will have to build custom-made platform channels in such situation, which would take some time.

Bluetooth-enabled applications — This functionality may be created independently for Android and iOS and then integrated into the Flutter app. However, this may take some time.

Using Flutter to create an app

In our last article, we revealed the true Google plan behind Flutter. Flutter has also been around long enough to deliver an exceptional user experience. Flutter's rapid rise in popularity as a cross-platform framework prompted developers to use it to create apps. There is now a plethora of flutter multi platform apps available, many of which are supported by professional flutter app development services.


Flutter applications produced by Google include the Adwords app, which measures advertising reach, and the Alibaba app, which is owned by Alibaba Group, a Chinese e-commerce business. Watermaniac, Hookle, Coach Yourself, Reflectly, and many others are examples.


Developing an app with Flutter is faster and less expensive from the perspective of the app owner. Other benefits of utilising Flutter for app development are covered further down:


Flutter App Development's Pros and Cons


Hot reload — Any changes made to the programme are instantly visible to the developers, making the process simple and efficient. Developers may use hot reload to rapidly modify anything in the programme that doesn't appear or fit well. This also makes it easier for engineers and designers to work together. However, it may take several minutes for the modifications to take effect.

Perfect for an MVP — Flutter is the greatest choice if you need to develop something rapidly to present to potential investors. It takes less time and creates an app that looks native on both iOS and Android. This will allow your investors to view your MVP, and you will save time by not having to create apps for two distinct platforms.

Flutter employs the Dart programming language, which is an object-oriented programming language that requires less code. Because it enables for hot reload, it does not necessitate coding a whole new application whenever any modifications are made. Flutter is reactive and declarative, and it is similar to react native.

Cross-platform development — Flutter is a platform-agnostic programming language. The coding is done only once, and the same code may subsequently be utilised on several platforms. Also, with Google's Fuchsia platform, Flutter is the sole way to build. Developers are experimenting with the Fuchsia developer portal now that it is online. Based on its current response, it is expected to eventually replace Android, which is precisely Google's aim behind Flutter.

Widgets — Having a large number of natural-looking, quick, and customizable widgets is an important feature of flutter for app development. Widgets are required for an app since they are what keep it interesting. Flutter offers a tonne of great widgets that work well and can be modified to fit your needs. All platforms and layouts have the same widgets.

Different themes — For the most part, the themes of the same software for iOS and Android are different. The distinction is not only in the colour and design of the theme, but also in the content. While coding for both platforms, Flutter lets you to use multiple themes. See how the theme data is configured for the target platform iOS in the image below.

Flutter Cross Platform App Development's Cons and Drawbacks


Solely for mobile — Developing an app with Flutter implies developing an app that is only for mobile. Web browsers are still unable to use Flutter. This might have a significant influence on your choice of development platform. If you're searching for the most flexibility, Flutter might not be the best option.

Flutter has a few libraries, but they aren't all that extensive. Many important libraries are still missing, despite Google's decision to add the most prevalent ones. If a developer wants to utilise one of the unavailable libraries, he must create it himself, which is a lengthy procedure.

Flutter development is supported on both iOS and Android mobile devices, however it is not accessible for Apple TV or Android TV.

There is currently no CI support — Other systems, like as Jenkins and Travis, provide continuous integration support for iOS and Android apps, but Flutter does not. Instead of these CI systems, there are alternative ready-made solutions, but developers will need to set up toolkits to use them.

Rapid Results and a Smooth Development Cycle

Flutter has a number of features that make the development process easier for engineers. Based on my experience with Flutter-based jobs, some of the most essential aspects are listed below:


Components of business logic (BLoC)

The concepts of Flutter are based on reactive programming, which predicts streams. BLoC is the name of this architecture pattern (Business Logic Components). Using streams, this design allows the application's UI to be separated from the business logic.


The essential advantage of BLoC design is its responsiveness, as well as the separation of the user interface from the data. In contrast to other architectural patterns where the UI may be layered with delays, the BLoC architecture uses organised, async methods, and streams to prevent delays in the application's performance. It indicates that while data is stacked from the server, animations and screen scrolling will be simple.


For years, we've been using the BLoC pattern architecture. It is best suited to applications with a complicated architecture and a large amount of data. When the app's architecture is basic, the Provider design is used as well, which simplifies resource allocation and enhances class scalability.
