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,
        ),
      ],
    ),
  );
