If I use Xcode or visual studio all I have to do is hover my mouse (Or alt + hover) to get more information about what the variable is returning or expecting. How can I do the same thing in android studio?
Do I have something toggled off or does android studio not support something like that?
One way I've found is simply placing the caret on the variable, and pressing F1. (Works with Flutter).
Alternatively, you can go to Settings->Editor->Code Editing and turn on Show quick documentation on mouse move.
In newer versions of android studio it is "Ctrl + Hover"
EDIT
On variable declaration line using "Ctrl + Hover" will show "Usages of variable".
On later usage of the variable it will show you its correct data type.
