Android Studio where is color picker for Flutter plugin

In Android Studio, we have color picker when developing in Java/Kotlin (natively) like this.

But while developing for Flutter, I can't see any options to pick my own color. Is there some plugin required to do that?

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.

Expert tip:

Add color picker to a keyboard shortcut. You can find the settings for Keymap, under File > Settings > Keymap
