           AOT snapshots can be obfuscated: that is all identifiers will be
           renamed
           during compilation. This mode is enabled with --obfuscate flag.
           Mapping
           between original and obfuscated names can be serialized as a JSON
           array
           using --save-obfuscation-map=<filename> option. See dartbug.com/30524

           for implementation details and limitations of the obfuscation pass.

I had already install flutter plugins and dart plugins.

Uninstall both plugins then reinstall and after than invalidate cache and restart the studio . Worked for me

How to  invalidate cache?

Another case of https://github.com/flutter/flutter/issues/48568 and friends.
@godot0413301 Where did toolbox put your Android Studio installation?

my androidsdudio4.0.1 path is '~/.local/share/JetBrains/Toolbox/apps/AndroidStudio/ch-0/193.6626763/bin$ ./studio.sh'.that is right,but flutter doctor show version is 4.0,and cannot find the plugin
