Introducing Features of Flutter 3.19 

Executing AI with Gemini Models 

The recently released update on Flutter 3.19 includes Google AI Dart SDK's beta version, which tends to improve Flutter app development with AI-based capabilities. Based on Google's Gemini AI assistant, the SDK enables apps with content creation and summarizing tools, therefore enabling the integration of generative AI to produce films, photos, and software codes.   

Scrolling Enhancements 

In previous versions of Flutter, two-finger scrolling doubled in speed. The new MultiTouchDropStrategy lets you control the default scroll behavior for multi-fingIt' scrolling. Included to handle unforeseen behavior and crashes are bug patches for the Reorderable List and SingleChild Scroll View.  

Animation Style Enhancements

SegmentedButton.styleFrom 

AcarFurkan, being a member of the Flutter community, added a style from a stationary utility technique for fast ButtonStyle creation for a segmented button. This approach can be applied to set the SegmentedButtonTheme of an application or shared with extra segmented buttons.  

Adaptive Switch

Hire Flutter developers who can use adaptive elements to attain macOS's native lookup while executing Material Deon on different operating systems. This concept is totally free from the Cupertino library, making sure the API appearance is consistent across distinct platforms. 

API Improvements 

In the recently launched Flutter iteration, version 3.19, observable enhancements foster AI integration, API refinements, and framework enhancements. On the dart:ui Paragraph object, the new Flutter 3.19 update comprises two new methods, getGlyphInfoAt and getClosestGlyphInfoForOffset. Both approaches produce a fresh kind of object called GlyphInfo.

GPU timing for debugging and profiling builds is now supported by the Flutter engine under Impeller. DevTools lets you view GPU frame timing. Using a setting in the AndroidManifest.xml file, developers may be able to enable GPU tracing on Vulkan-powered Android devices. 

Improvements of Flutter Engine Android OpenGL 

The Android OpenGL in the Flutter Engine has been improved in Flutter 3.19 as follows: 

Impeller enhancement: It is one of the features of Flutter 3.19. This version introduces an impeller capable of running Android devices enabled by Vulkan. The Flutter app development services with striking graphics and flawless rendering speed can be driven by the Impeller rendering engine.    

Full-Functioning Impeller on Vulkan and OpenGL backends: The Impeller is gradually coming closer to working perfectly for Vulkan as well as OpenGL backends. Numerous competencies are generated, like custom shaders and optimal assistance for external textures.    

Multisample Anti-Aliasing for Image Detailing: Increasing the visual appeal of the app is prioritized every time, and MSAA keeps an aim to do that. It offers smoother graphics and text to improve the presentation of Flutter-based apps. 

Android Upgrades of Flutter 3.19 

• Share.invoke Support: In the old version of Flutter 3.16 on Android, the standard Share button vanished from text fields and views. Recent Flutter 3.19 fixes this issue, such that the default context menu button is now accessible on all platforms. 
• Deep linking Web Validator: Unlike the one in Flutter 3.16, the UI Kit in Flutter 3.19 has included a strong deep-linking web validation mechanism. This tool is meant to assist Flutter developers in replacing non-functional links and verifying information, therefore facilitating flawless and quick creation of Flutter apps.
• Native Assets Feature: Android allows you to use FFI calls via Native Assets if you search for information regarding Flutter's interoperability with Flutter's functions in many programming languages.
• Customisable System-Wide Text Selection Toolbar Buttons: The most recent release to Flutter version 3.19 lets Android developers take advantage of unique text selection menu items seen on all text-selecting menus. This lets the Flutter TextField selection menu incorporate these objects.

• Texture Layer Hybrid Composition (THLC) Mode: The new Flutter release improves efficiency by combining Google Maps with a text input magnifier in TLHC mode. If you frequently use Google Maps, check the updates and provide comments.

iOS Updates of Flutter 3.19 

• Flutter iOS Native Fonts: In the recent release, text rendering allows a highly native and compact look for Apple devices. The update makes sure the readability is easy for small fonts while enabling smooth integration of native fonts into Flutter app development.   

• Performance Optimizations: Recent Flutter 3.19 updates have offered enhancements in performance optimization.  

• Specialization Constants: The most recent Flutter release now provides Impeller with support for specialty constants. Using Impeller's shaders' advantages helps the Flutter engine's uncompressed binary size to be lowered by up to 350 KB. 
• Windows Arm64 Support: The Arm64 architecture is now supported in the most recent Flutter 3.19 for Windows. Now running straight on Windows Arm64 devices, cross-platform Flutter apps greatly increase Windows device compatibility and performance.  

Important Fixes in Flutter Launch 

• A Flutter app development company can utilize the upgrade command to allow the switching of channels. 
• Fix memory leaks both inside WidgetInspector and across WidgetInspector Service are permissible.
• Windows leak-tracking targets in the latest edition help to fix application test failures linked to leak tracking.
• The chip widgets must be fixed since the given application causes them to not be working as intended.
• The new version includes Fix Doc TODO.
• It provides a command-line argument to enable leak tracking turned on.
• For testing, the community has unveiled the Bump template and incorporated the Gradle version 7.6.4.
• The most current iteration lets [flutter_tools] run tool integration tests, allowing for SIGINT quitting.
• There are now updated leak tracker libraries available for use.
• The test is now looking for memory leaks in Cupertino; the Opacity Layer's problem still has to be fixed.
