Android Studio freezes with flutter when changing files

[jmagman]

Copied from @Elsrougy report at flutter/flutter#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:

It looks like the survey contents are being read on the main thread?

Thanks for the report! This was fixed by @pq yesterday in #4469.

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

@jmagman, @Elsrougy: super sorry for the hassle here.

@stevemessick kicked off a dev build with the fix. If you want to give that a whirl, the instructions are in the wiki here:

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.

Completely freezing my system when I run a flutter project.

Android studio just dies when I change code in the exact specific file.
