Language Features of New Flutter 2.2


In the previous Flutter 2.0 version, Google introduced sound null safety that enables developers to indicate if a variable or value can be null directly from the code. In Flutter 2.2., null safety is enabled by default in new projects.

Other than null safety, there are some other performance improvements in Flutter 2.2. When developing for the web, you can cache resources in the background with the help of service workers. In the case of Android, you can utilize deferred components that allow you to download Flutter components at runtime as per requirements and reduce app size.

For the iOS platform, you can precompile shaders to make smoother animations when executed for the first time. Also, there are new tools available in the DevTools suite that allow you to evaluate memory usage in your app and detect problematic areas.

Flutter 2.2.0 also comes with other new features and SDKs. First, there has been more focus on making web apps more accessible. When talking about SDK, the Flutter Ads SDK has been updated with default null safety and adaptive ad banners. Lastly, Flutter is also introducing a new payment plugin, built in partnership with the Google Pay team, that allows developers to process online payments for physical goods on Android and iOS. Flutter has also been updated with their in-app purchases plugin as well as matching codelab.

With all these language features of Flutter 2.2.0, you can opt for Flutter mobile app development services and solutions to build highly captivating and robust cross-platform applications.

Dart also has official GitHub Actions support and an official Docker image for automated development and execution.

New Platforms

The first one is Flutter for Tizen. Tizen is an open-source Linux-based OS used by Samsung on its smart devices such as TVs and smartwatches. Usually, you can build apps using JavaScript, C++, or C#. Samsung has made efforts to develop an extension for Flutter SDK to allow developers to create Tizen apps. Although it is still in the initial testing phase, it’s a favorable start and further extends Flutter’s reach.

The second one is Flutter for UWP. Universal Windows Platform or UWP and is used for developing modern apps in Windows 10. UWP support gives the ability to build more native-like apps for Windows. Just like Flutter for Tizen, it is an alpha, therefore, it is not really ready for primetime.
