Flutter: How can I make a Random color generator Background

Question

Generate random colors

return new RaisedButton(       padding:  EdgeInsets.symmetric(vertical: 30.0),     color: Colors.primaries random  List <blue,green>, 

Answer 1

This is my way to get a random color:

Color((math.Random().nextDouble() * 0xFFFFFF).toInt()).withOpacity(1.0) 

Note:
This import is required.

import 'dart:math' as math;
