Flutter-intellij: Android Studio freezes with flutter when changing files

[jmagman]

Copied from @Elsrougy report at https://github.com/flutter/flutter/issues/54222:

I had flutter with android studio for a while now and everything is working great until one day in any flutter project when I try to open any file android studio freezes for few minutes. For example, if I was in the main.dart file and then switched/opened another file the freezing occurs, and that happens in any file not just main. This freezing doesn't happen with normal android studio projects only with flutter

it's worth mentioning that in android studio plugins it always says can't load marketplace and to check the connection but I don't know when did that started and if it is related or not.

Also flutter analyze is taking a long time with no output. I tried reinstalling flutter, reinstalling android studio, reinstalling flutter (stable and beta), installing android studio beta instead of stable and nothing happened still the same problem

attached is idea.log and threadDumps-freeze that android studio generates.

flutter doctor -v output:

Thanks for the report! This was fixed by @pq yesterday in https://github.com/flutter/flutter-intellij/pull/4469.

@stevemessick, I think we'll need to release a new version with the fix for this.

I do think that we need to release a patch to the stable release channel as well, otherwise users will have to wait a month for the fix.
