In the latest Flutter update, Firebase extended its support and incorporated Flutter as a first-class integration. Programmers will leverage improved documentation, tooling, and exceptional widgets such as FlutterFire UI. It provides a reusable UI for profile screens and auth.
Many app development platforms are accessible for game development but Flutter 3.0 drives some thrilling updates for casual game developers.
Flutter provides a Casual Games Toolkit with templates’ starter kit and casual game development best practices. The game development community gets the advantage of an open-source Flame engine and hardware-expedited graphics to build casual games. Nevertheless, Flutter is not for game development that includes high-performing 3D action.
Flutter framework is empowered by a multi-platform, highly productive, and portable Dart programming language formed by Google. It helps with simplified UI creation for mobile and web platforms. Dart’s latest version 2.17 emerged at Google I/O 2022 with new features and updates.

Flutter 3.0 enables you to avail of this using Flutter Crashlytics Plugin. It provides multiple features to developers to ensure app stability.
Some performance improvements get released with Flutter’s 3.0 version such as,
Better opacity animations execution in simple cases
Modernised policy for raster cache admission
Partial repaint availed on Android devices
Experimental rendering back-end called Impeller
Quick frame development times because UI threads execute at a priority on iOS and Android
Additionally, multiple pull requests are combined to provide Flutter with a significant performance boost over the former version.
Flutter web apps get a new lifecycle API with the release of the Flutter 3.0 version. It helps developers to manage the app’s bootstrap process. It is implemented in multiple cases including,
A Splash Screen
A loading indicator
An HTML landing page is shown before the Flutter App
Flutter 3.0 has announced foldable mobile devices support that enables developers to build engaging, responsive, and lively experiences through new features and widgets.
As mentioned above, the Flutter framework is now used to build apps for iOS , Android, Web, Windows, macOS, and Linux platforms. It helps with accessibility services like inverted colours, screen readers, accessible navigation , etc.
The old Windows versions are not supported by Microsoft anymore. With Flutter 3.0, the community also endorsed the Windows 10 version for development. However, the Flutter framework now provides restricted testing on older versions. The Flutter community keeps supporting Flutter apps running on Windows 7 and 8.
