"Pubspec has been edited" always reappears in Android Studio

### Steps to reproduce

1. Open a project
2. You will be warned by the "Pubspec has been edited" banner (even if there is no change).
3. Click Get or Update
4. The banner disappears
5. Switch to any .dart file within your project
6. The warning reappear (even the "ignore" button does not help)

My pubspec.yaml file does not have a fresh change date when taking a look at it in the Finder.
I didn't have this problem until some days ago.
I think there was a Flutter or Dart plugin update some days ago?

### Expected results

The banner should disappear when upgrade or get process are done and only reappear after a real pubspec.yaml change.

### Actual results

The banner reappears all the time.

Start by reproducing the repeated “Pubspec has been edited” banner in Android Studio with the listed Dart and Flutter plugin versions, using the pubspec.yaml change state and the Get, Update, and ignore actions described. Done means the banner disappears after a completed get or upgrade and returns only after a real pubspec.yaml change.
