Flutter Google cross-platform UI framework has released a new version 1.20 stable.
Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, 
Mac,  Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already 
 achieved popularity among mobile developers to develop Android and iOS apps. In 
 the last few releases, Flutter also added the support of making web
applications and desktop applications.
Last month they introduced the support of the Linux desktop app that can be  
distributed through Canonical Snap Store(Snapcraft), this enables the developers 
to  publish there Linux desktop app for their users and publish on Snap Store. If 
you  want to learn how to Publish Flutter Desktop app in Snap Store that here is 
the  tutorial.
Flutter 1.20 Framework is built on Google’s made Dart programming language 
that  is a cross-platform language providing native performance, new UI widgets, 
and  other more features for the developer usage.
Here are the few key points of this release:
Performance improvements for Flutter and Dart
In this release, they have got multiple performance improvements in the Dart  
language itself. A new improvement is to reduce the app size in the release versions 
 of the app. Another performance improvement is to reduce junk in the display of 
app  animation by using the warm-up phase.
If your app is junk information during the first run then the Skia Shading  
Language shader provides for pre-compilation as part of your app’s build. This 
can  speed it up by more than 2x.
Added a better support of mouse cursors for web and desktop flutter app,. 
Now  many widgets will show cursor on top of them or you can specify the 
type of  supported cursor you want.
Autofill for mobile text fields
Autofill was already supported in native applications now its been added to the  
Flutter SDK. Now prefilled information stored by your OS can be used for autofill 
in  the application. This feature will be available soon on the flutter web.
