Description
Got this while using the library:
`The following assertion was thrown while notifying listeners for AnimationController:
type 'double' is not a subtype of type 'int' where
double is from dart:core
int is from dart:core
`
Changing line 181 in `color_picker_widget.dart` from
`new Tween(begin: 0, end: _lastColorList.length).animate(controller)`
to
`new Tween(begin:0.0,end: _lastColorList.length).animate(controller)`
fixed it for me.
Thanks.

Start in color_picker_widget.dart at line 181, where the reported AnimationController assertion occurs. Reproduce the color-picker interaction that triggers the exception and verify that it no longer reports a double-versus-int type error.
