The open-source user interface and SDK (software development kit) Flutter have been created by Google. It can be used for building applications for a wide variety of operating systems, including iOS, Windows, Mac, Linux, and of course, Android. Dart, the language used for creating apps in Flutter, has some very advanced features as well, much to the delight of developers. Flutter is a hybrid or cross-platform app development framework, which means that developers can write new apps through writing a single code, which saves them time, effort, and money. There are no OEM widgets in Flutter, but the platform has its widgets for the iOS (Cupertino) or the Android (material design) apps. The UI of Flutter has many widgets, and each of these widgets has a style element (for instance, color or font scheme), a structural element (for instance menu or button), and a layout element or aspect (for instance padding). Flutter now ranks among the top 30 app development platforms, in only a few years of its existence. Below are some of the benefits of Flutter, especially for app developers. 

Benefits of Flutter:

Enhanced productivity

This cross-platform app development platform can be used to create apps for both iOS and Android. Developers can now save on multiple resources and reach the highest productivity by using the platform.

Better performance

With Flutter, developers are not required to access the OEM widgets. It can easily compile within the native code. It can provide reactive views and does not need a bridge for JavaScript. With lesser mediation between the platform and the app, the app start-up times enhance, and the performance-related problems reduce. Programming on Flutter can be up to 1.7 times faster, and implementation is also expedited. Different teams can work on the same project, and excellent communication ensues.

Compatibility

Widgets in Flutter are part of the apps and do not form a part of the platform itself. Hence the developers will not face any compatibility related problems and issues when they try and test the apps on the different versions of operating systems. Developers can easily save on time they spend on testing the apps. 

The speedy and fast development of apps

The “hot reload” feature of the Flutter application development platform helps developers view the emulator/simulator/hardware code changes instantly. Therefore, the code reloads along with the changes instantaneously, and there is no need to restart after each subsequent change. Apart from building user interfaces, the functionality also extends to bug fixing and testing. Google assures developers that they will find programming quite easy in Flutter and that no prior knowledge in the area is needed before they start to use Flutter. Therefore, while some experience in languages related to programming might be beneficial, those from non-programming backgrounds can also make Flutter apps quickly in the least amount of time.

Benefits of open-source

The free and open-source Flutter application development platform offers extensive community support and extensive documentation. This helps in overcoming issues quite easily.

Better quality

Flutter can provide for a better quality of work, which is evident in the results. Flutter can be used for creating flexible user interfaces tailor-made for a requirement. Further, the platform can also be used for building PWAs or progressive web applications.  Because PWAs and their importance are growing for businesses, learning Flutter app development and Dart can have immense benefits for the developers.

The time consumed in project stages, like quality assurance, is also reduced to a great extent with the use of Flutter. Some developers opinionated that the reduction may be close to 50%. Now all data can be compiled in a matter of seconds. Because up to 70% of the source code can be shared, the efforts are reduced. Developers can focus more on the quality aspects of things, thus, and produce quality apps that attract attention and popularity easily.

Restrictions of Flutter:

There may be certain restrictions or drawbacks of using Flutter. Below are some of these.

Learning a new programming language

The developers need to learn a new language, which is the Dart programming language. Dart is as new as Flutter, and hence there might not be enough developers and people knowledgeable in the language. Hence the Flutter application development projects may face drawbacks and be delayed when adequate staff is not present. Still, Dart is simple and easy to learn, and serious developers should try to learn it for better expertise and prospects.

Writing native codes

Developers may be required to write specific codes as the library may not have all the functions and may be missing some crucial links. Sometimes, an add-on may need to be provided, and the existing solution may not contain it. Hence sometimes developers may be required to build their solutions as well.

Delays

The upgrades in the operating systems may turn to be problematic for developers, as the apps need to be upgraded to these versions.

Deviations from native behavior

Sometimes, the app developers may do their best, and still, some differences with the native versions may exist. The app may show slight differences from the behavior of the natives. For instance, such a difference can be found in the ripple animation when the user chooses the clickable elements found on cards and lists. Here the flutter background may carry some difference.

May not suit complex apps

The other restriction may be that for some apps, more native features may be required. Hence Flutter application development platform may not suit the gaming apps or the apps that need the device-related/specific functions. Some developers also believe that Flutter may yield good results for building prototypes and simpler apps, but it may not be suitable for building more complex apps. However, when one searches the app market like Play Store and iTunes, we find a range of apps built using Flutter, including Alibaba, Dream 11, Google Ad App, and HuYu, among others.

Therefore, before choosing the best Flutter app development company, you should see to it that the platform meets your requirements.  One should also check the system-related requirements, for instance, compatibility of windows with the language and Flutter installation and Flutter SDK, among others.
