Autocomplete not working correctly in Android Studio with Flutter - First suggestions are irrelevant

Question

I installed Flutter and Android Studio. I ran flutter doctor - Flutter doctor

I have the Dart plugin installed - v191.8593.

When I press Ctrl + Space at a very obvious place the AutoComplete do not suggest the right suggestions. Example:

View animation here

As you see the first suggestion are not of type ScrollPhysics and are out of context, and after I scroll down, there are ScrollPhysics suggestions, but they are after some scrolling.
