Flutter 3.7 – What’s New In Flutter

With the recent release of Flutter 3.7, the mobile app development platform gained a number of new features and enhancements. You can now use tools to enable improved internationalization, make use of new debugging tools, and construct custom menu bars and cascading menus.


Together with these new features, previous features have also been improved. They include the quicker global selection tool, the Impeller rendering system, and the capacity to share resources between platforms.


Here are a few of the major improvements that this most recent edition offers developers.


Null Safety:


The addition of null safety is one of the most significant changes in Flutter 3.7. This feature makes sure that variables are always initialized before usage, preventing frequent runtime errors and improving the dependability and maintainability of the code.


Enhancements to Web Support:


The release of Flutter 3.7 brings a number of web support enhancements that make it simpler to create web applications that are of a high caliber. Improved support for the desktop platform is included, along with faster performance and lower software sizes.


Tools for internationalization:


It is now simpler to translate and localize your Flutter app thanks to a new internationalization system. Even those with little coding knowledge may understand error messages because of the informative syntax.


Enhancement of Material 3 Support:


Material 3 support has been added to Flutter. You can use the material components given by the most recent Android version thanks to this update. A modern new theme included in the Material Pack will make your content stand out strongly and clearly. Both iOS and Android are supported.


Enhancements to the DevTools debugging tool:


These are also part of Flutter 3.7. In addition to new features like the capacity to save and share customized layouts, this also boasts improved performance and layout.


Text enlargement:


Flutter now supports the magnifying glass that shows when text is selected on Android and iOS. All apps that support text selection have this enabled by default, but you may change it or disable it by using the magnifierConfiguration property.


Upgraded Widgets:


Flutter 3.7 now comes with a number of fresh and improved widgets that simplify the development of premium mobile applications. These widgets expand on already-existing ones like the “slider” and “checkbox” widgets and introduce a new “toggle buttons” widget for designing unique toggle buttons.

A number of performance enhancements have been made to Flutter in version 3.7, making it faster and more effective than before. Faster hot reload times, less memory utilization, and quicker programme launch times are a few examples of this.


Menu Bars and Cascading Menus:


PlatformMenuBar and Material Design Menu are two new menu widgets included in the most recent Flutter update. On macOS, PlatformMenuBar is an option that renders native menu bars rather than using Flutter. You may create a Material Design menu for all platforms that offer cascading menu bars (MenuBar) or individual cascading menus that are triggered by other UI elements (MenuAnchor). These menus can be totally customized, and the menu items can either be new menu item widgets or customized widgets (MenuItemButton, SubmenuButton).


iOS release validation:


A list of settings to update when releasing an iOS app ensures that your app is prepared for submission to the App Store. Several of these settings are now verified by the flutter build ipa command, which also alerts you if your app needs to be changed before being released.


Unique context menus:


In each location within a Flutter app, you can now develop unique context menus. Also, you can utilize them to alter built-in context menus.


Bitcode expiration:


The App Store no longer allows bitcode submissions from Xcode 14 and watchOS and tvOS programmes are no longer required to be written in bitcode as of Xcode 14. Bitcode support has therefore been dropped from Flutter.


Background separations:


Today, any Isolate can call Platform Channels. Before, customers could only call Platform Channels from the primary isolation that Flutter provided. This improves how isolates and host platform code are used in plugins and add-to-apps. 


Memory management:


A few memory management improvements are included in this release that together reduces junk brought on by garbage collection pauses, CPU utilization brought on by allocation velocity and background GC threads, and memory footprint.


Improvements to the support for custom shades:


This version significantly enhances Flutter’s support for client fragment shaders. The GLSL shaders are listed in the pubspec.yaml files are now converted by the shader compiler in the Flutter SDK to the appropriate backend-specific format for the target platform. Moreover, for an easier development cycle, custom shaders can now be hot reloaded. Currently, the iOS Skia and Impeller backends both support custom shaders.


Enhanced Documentation:


Last but not least, Flutter 3.7 features revisions to the documentation, making it simpler to start using the framework and locate the knowledge you need to create top-notch mobile apps


In conclusion, the mobile application development framework receives a number of new features and improvements with the release of Flutter 3.7. Developers have a lot to look forward to in this most recent edition, from null safety and web support improvements to redesigned widgets and enhanced speed. Whether you’re a seasoned developer or just starting started with Flutter, version 3.7 will allow maximum a more effective and dependable work environment.
