Try restarting the dart analysis server -

  • Navigate to Dart Analysis tab at bottom.
  • Click Restart Icon (red colored icon on top left corner of Dart Analysis Window)
  • Wait for dart analysis to finish.

After these close and restart the android studio.

Hope it helps.

It happens to me too and I solved it by pressing (Ctrl + O) to show Override methods and I think the next dart update will solve the problem.
