A custom implementation of Flutter's showModalBottomSheet

THIS PLUGIN IS NOW DEPRECATED

You can now properly use borders with the default implementation of showModalBottomSheet!

showModalBottomSheet(
  shape: RoundedRectangleBorder(
     borderRadius: BorderRadius.circular(10.0),
  ),
  backgroundColor: Colors.white,
);

A custom implementation of showModalBottomSheet.

Instead of overriding the entire theme of the app (which caused problems in various parts of my app) as suggested by other solutions on "How to set rounded corners of a modal?", I decided to take a look at the implementation for showModalBottomSheet and find the problem myself.

Getting Started

Turns out that all that was needed was wrapping the main code for the modal in a Theme widget that contains the canvasColor: Colors.transparent trick. I also made it easier to customize the radius and the background color of the modal itself.

import 'package:rounded_modal/rounded_modal.dart';

showRoundedModalBottomSheet(
   context: context,
   radius: 10.0,  // This is the default
   color: Colors.white,  // Also default
   builder: (context) => ???,
);
