Why isn't Android Studio showing widget elements on mouse click?

Question

I saw a video tutorial on flutter coding, of mouse clicking on a widget showing additional information about widgets. Details of that are shown below.

But when I wrote the same code in Android Studio, it didn't show me that additional information. Why is that, and how can I change it?

Answer 1

In Android Studio Goto

 File->Settings->Editor->General

and Enable

Show quick documentation on mouse move.
