feature: enanble custom TextSelectionControls

[kfdykme]

Hello, there is a bug in Flutter's OverlayEntry handling related to TextSelectionTheme.of(context). Specifically, the issue causes the color of MaterialTextSelectionControls to be lost when buildHandle is called. This can be seen in the Flutter source code at https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/material/text_selection.dart#L77.

A simple way to fix this issue would be to allow developers to use a custom TextSelectionControls implementation.
