Use case

Customize the barrierColor used in showDialog globally. This can help to provide better barrier contrast in themes that are almost black, where the default value of black54 as barrier doesn't help much in distinguishing the modal barrier.

Proposal

Same as in BottomSheetThemeData, we could have a barrierColor property to customize the showDialog globally.

Reference implementation from showModalBottomSheet:

flutter/packages/flutter/lib/src/material/bottom_sheet.dart

Line 1272 in 995e3fa

modalBarrierColor: barrierColor ?? Theme.of(context).bottomSheetTheme.modalBarrierColor,
