Sound Null Safety
This feature will allow developers to specify if any value or variable can be null directly in the code. Kotlin also has the same feature that makes null-pointer-related errors less common. The new feature in Flutter 2.2 will be enabled by default.
-
Performance Enhancements
Background caching by web applications can be done by service workers and Android and iOS developers. It also enhances performance. A DevTools suite will help you increase performance and improve memory allocation during runtime. Additional support for 3rd-party extensions will help developers get a better experience and enhance performance across various platforms.

Tighter Integration with Google’s Ecosystem
Google released a new in-app payment plug-in from the Google Pay team. With the Google ecosystem, this plug-in lets users process payments using their apps smoothly and hassle-free.

Improved Web Platform
The new release has optimized caching behavior with a novel service worker loading mechanism. You will also find improved web renderers with canvas APIs for text rendering, shader mask support, font feature support for HTML, and opacity masks for transition performance. Moreover, a better semantic node position will lessen the space between mobile web and desktop apps.
