It is one of the most recent iterations of Google’s Material Design. Material v3 is an excellent language of Material Design that includes new shapes, color effects, themes, etc. It comes with huge FAB sizes as well as theme choices. Even though it seems pretty good, Google is still making progress in it.


3. Performance


Flutter 2.5 includes a multitude of performance improvements. Some of its common improvements are listed below.

  • Async tasks
  • Shader warmup of iOS
  • Message passing and GC

One of the best performances is the PR that tap shader precompilations from training runs done offline. This cuts the times of worst-case frame rasterization by 2/3s. It also cuts the frame of the 99th percentile by half. Along with this, the iOS jank is reduced. Another jank cause is the garbage collector of GC that pauses the thread of UI to again claim its memory. Earlier, Dart VM performed GC that lazily reclaimed the memory images. But this practice led to many low-memory situations in devices. In the new version, unused images memory is reclaimed well, which reduces GCs.

The newest MaterialState.scrolledUnder state allows you to view in action and sample PR codes (#79999). With the alerts of scroll metrics inclusion, one gets notifications about the scrollable region even when users are not scrolling. For instance, depending upon the ListView size, the scrollbar disappears or appears. The Flutter app developers do not have to write codes in this case, but they can if they want the ScrollMetricNotificationchanges.


5. Support for Material Banner

The Material Banner inclusion into ScaffoldMessenger is also a great effort taken from the Flutter community. It is a sophisticated approach for presenting SnackBars in the bottom screen to provide users with alerts. You can put banners on top of the scaffold that will remain in place as long as the user cancels it.

The command Repair All automatically formats and fixes lint issues in files. Flutter and Dart code test runners are also available and can be activated as well. Moreover, the plugins are not marked as Flutter’s Favorite plugins anymore as they are not properly maintained.


7. IntelliJ/Android Studio IDE Plugins

The tests are executed well on any device and have their directory. There is the availability of integration tests and coverage reports. While acquiring fonts from the, you can see the TrueType font icons.
