Android Studio Flutter Tooltips Not Showing

Question

I am following along a tutorial for Flutter using Android Studio. The instructor's screen shows more detailed tooltips / hints than my environment does.

I am unsure of how to enable these extra details.

Examples

Instructor's Screen (extra tooltip details in red):

My Screen

Answer 1

Go to Preferences->Editor->General->Code Completion

Check the box "Show the documentation popup in xxx ms"

Answer 2

After having the Basic Code Completion open (Control + Space), then hit Control + Q (Win/Linux) or Control + J (Mac) to open the Quick Documentation Lookup, this will make your screen appear as your instructors. Alternatively, just hit the last keyboard shortcut to only see the Quick Documentation Lookup.
