Change gray overlay background of BottomSheet
Solution 1
New Flutter UPDATE allows you to change the barrierColor
in showModalBottomSheet()
showModalBottomSheet(
barrierColor: Colors.yellow.withOpacity(0.5),
Solution 2
You can actually change this but in order to do so you have to create a copy of this widget file in order to customize it. (steps below are for vscode)
However, by doing this, the widget won't be automatically updated by Flutter because it'd no longer be part of the SDK.
Create A Copy of A Widget To Customize
-
Right-click widget and select
Go to definition
- this will bring you to the widget's original file -
Copy all of the code and paste it into a new .dart file with the same name - you'll notice there will now be errors due to a lack of dependencies.
-
In the case of BottomSheet you just need to add
import 'package:flutter/material.dart';
-
Now import it like so
import 'package:projectname/bottom_sheet.dart' as my;
- theas my
allows it to use the same .dart file name -
Now when referencing it just add
my.
prior like so
my.showModalBottomSheet(
context: (context),
isScrollControlled: false,...
Customize Background Overlay Color
Now in bottom_sheet.dart
just search for barrierColor and change Colors.black54
to whatever color you want!
I hope this will help anyone in the future!

Short answer : you can't.
The color is hardcoded into the _ModalBottomSheetRoute
class (as linked by @pskink) and there is no way to change its value.

Is there a way to change the overlay background color when using
showModalBottomSheet
?Right now the color is always a gray color, but I want to use a different color like green as shown below.
Here is the code used in the demo for reference
showModalBottomSheet<void>(context: context, builder: (BuildContext context) { return Container( child: Padding( padding: const EdgeInsets.all(32.0), child: Text('This is the modal bottom sheet. Tap anywhere to dismiss.', textAlign: TextAlign.center, style: TextStyle( color: Theme.of(context).accentColor, fontSize: 24.0 ) ) ) ); });
