The color picker is not clickable in Android Studio running Flutter( Dart code), see picture below. But i found a work around using the
Color class and manually opening color picker. Then pick a color and copy/paste it like this:
Here is how i do it:
1. Double tap shift to run search
2. Type Color or Picker
3. Open Color Picker from the search list
4. Copy/paste the HEX color code into your color class.
Add color picker to a keyboard shortcut. You can find the settings for Keymap, under File > Settings > Keymap
