I had been developing a flutter mobile app for a couple of months and all was good. I just came back to the project and a few things (flutter, dart, android studio etc) upgraded. Now I can't compile my app. I created a new flutter app (the default example) and that won't compile either.

The error I'm getting is :

FAILURE: Build failed with an exception.

* What went wrong:
Could not open settings remapped class cache for bq3hllkgb26p0nrblf5gh8d37 (C:\Users\Paul\.gradle\caches\5.6.2\scripts-remapped\settings_cbd968glg60byp9f5t6vvdlee\bq3hllkgb26p0nrblf5gh8d37\settings8410a2d21ed2f87c8a0398566330ee52).

Try running

flutter stable
flutter clean
flutter downgrade
cd <Your App Folder>

and then

flutter run

in command line

I ended up completely removing Flutter from my system and then re-installed it. This fixed everything.
