Some important updates

1. Hot Reload improvements:

Improved reliability and quicker hot reload enable Flutter developers to observe changes as they are made in real time.

2. Dart DevTools enhancements:

Dart DevTools updates offer improved insights into app performance, memory utilization, and debugging options.

3. Integration with Visual Studio Code and IntelliJ IDEA:

improvements to the Flutter extensions for well-known IDEs, providing a fluid development environment.

4. ColorScheme.fromImageProvider():

The theme’s ColorScheme default colors are set in all M3 components. Shades of purple are used in the basic color scheme. A single “seed” color or a picture can be used to generate a unique color scheme. Try the demo with both options. The resulting color schemes should be aesthetically pleasing and user-friendly.

NavigationBar widget in Flutter 3.10

This offers an M3 version of the widget. M3 functions like before despite using new colors, highlights, and elevation. Use the NavigationBarTheme widget to alter the NavigationBars widget’s default appearance. Although migrating already-installed apps to this component is unnecessary, you ought to do so for new apps.

NavigationDrawer

This offers a Drawer widget-based M3 destination selection widget. NavigationDrawer displays a single-selection list of NavigationDestinations widgets. Other widgets can be added to this list as well. When necessary, the NavigationDrawer can scroll. Use the NavigationDrawerTheme widget to alter the NavigationDrawers widget’s default appearance.

SearchAnchor and the SearchBar

These components make Predictive text available for search queries. The software generates a list of relevant answers in a “search view” once the user inputs a search query. The user chooses either one, or the query is modified. Use the SearchBarTheme and SearchAnchorTheme widgets to replace the M3 design of these components.
