Future Proof Your Apps with Flutter Best Practices in 2023

Flutter is a free and openly available user interface developed by Google. The developers develop applications with Flutter to use only one code for more than one platform. In 2018, google launched Flutter, primarily focusing on mobile app development. Right now, flutter 3 supports six platforms, and they are MacOS, Windows, iOS, Android, the web, and Linux.

This blog includes the latest Flutter best practices the developers should keep in mind while developing the app so that the users love it.

Flutter Best Practices for Mobile App Development

In the present-day environment, there is so much advancement in technology, with the help of which the software development process is getting more complex. So, there is a need for best practices that the developers should follow, which will help them throughout the business app development process.

Suppose the creators sustain the Flutter best practices in mind while working on the app. In that case, it will help them in several ways, like it helps to improve the readability, quality, robustness, and maintainability of the code.

The Flutter best practices will help the developers collaborate as everyone is on the same page, and the work becomes more manageable. The below are some of the practices:

Creation of Pure Build Function

It is one of the essential functions as it will ensure whether the business app's performance is flawless. It is critical to remember that the application's performance is notably influenced by its pure build function.

E.g., If a pure build function of an application is designed flawlessly, then the performance of the application will be outstanding. In contrast, if the build function is not designed up to the mark, then performance will not be top-notch, and eventually, it will frustrate the user.

So the developers must design pure build functions very cautiously to improve the performance of the business apps and user experience. Thus Pure build function is one of the vital Flutter best practices.

Flutter BLoC Best Practices

The Flutter best practices also include BLoC, one of Flutter's essential features, which is used as a cross-platform mobile app framework. It is a design that is extensively used in the Flutter apps, and it assures that the application will respond to the user correctly and smoothly. If the developers use Flutter BLoC, it can handle all possible states comfortably, which is vital for any mobile application.

Determining App Architecture Distinctly

The Application Architecture must be distinctly determined, which is vital for making the Flutter business app development process easy. It is one of the essential Flutter best practices. The developers have to learn only one language to develop an application with the help of Flutter, which is Dart.

The developer has to determine the architecture adequately so that every process can be conducted smoothly, but in case the developers fail, then things might get worse. If you cannot determine the app architecture or have any problems regarding application development, then you can hire Flutter developer who will help you in all circumstances.

Refactor the Code into Widgets

Refactoring the code into the widgets is one of the great options in Flutter application development. This method will provide all the convenient widgets, features, and optimization offered by Flutter. We can easily avoid unnecessary builds when the code is refactored into the widgets. The rebuilding will occur only in the case of a change in the widget. Thus Refactor code into widgets is one of the essential Flutter best practices.

Test Execution

Automation in testing can help in saving the amount of time rather than manual testing. As the Flutter framework targets multiple platforms, testing every functionality is time-consuming. Thus automation testing should be executed in Flutter so that time and efforts of the developers can be saved extensively. Apart from the unit testing, integration testing should also be conducted to ensure all components work seamlessly together.

Using Dart Code Matrix

It is one of those Flutter best practices that help analyze the Flutter app's code quality. A dart code matrix is a static tool that helps improve and monitor code quality. The developer should perform a different task to use the dart code matrix effectively.

E.g., The developers should try to use only one widget for each file to ensure that the code is more modular and its readability and understandability are also increased.


So, as mentioned earlier, Flutter is one of the best tools for developing cross-platform frameworks and for developing business apps optimally; the developers should follow Flutter best practices if the developers follow the best practices, then it will surely help to future-proof their business applications. In case you need help in developing mobile applications, you can hire a Flutter app development company like bacancy, and we will help you in giving your application a competitive advantage.
