MaterialColorPicker not working in Dialog

[ckaotik]

When trying to place this color picker widget inside of an AlertDialog or SimpleDialog, an exception is raised.

However, be aware that since AlertDialog tries to size itself using the intrinsic dimensions of its children, widgets such as ListView, GridView, and CustomScrollView, which use lazy viewports, will not work.
-- Flutter docs

Would be great if there was support for this.

It worked for me in showDialog(builder: (context) => AlertDialog(..)..., but not in showCupertinoDialog(builder: (context) => CupertinoAlertDialog(..)...
