Color picker for Flutter, based on the Google Docs color picker.

Getting Started
You can embed into your material app or use it on a Dialog like this:
Future<Color> askedToLead() async => await showDialog(
context: context,
child: new SimpleDialog(
title: const Text('Select color'),
children: <Widget>[
new ColorPicker(
type: MaterialType.transparency,
onColor: (color) {
Navigator.pop(context, color);
},
currentColor: startColor,
),
],
),
);
