Flutter: BouncingScrollPhysics not working

Question

Minimal code:

ListView.builder(
 physics: BouncingScrollPhysics(parent: AlwaysScrollableScrollPhysics()),
 itemBuilder: (_, i) => ListTile(title: Text('$i')),
 itemCount: 50,
)

The BouncingScrollPhysics seems to have no effect. I am testing this on macOS.

• Md. Yeasin Sheikh: it works on windows perfectly. btw you can try flutter clean and rebuild
• iDecode: @YeasinSheikh flutter clean, full restart, nothing worked, however this code works on iOS. Maybe it's a bug on macOS.
• Passiv Programmer: Got the same problem on windows. If I fire up the Android emulator it works fine.
• Clifton Labrum: I'm also seeing this bug in macOS. I'm on Flutter 3.0.5.

You don't need to set parent argument. You can just set empty constructor and it will work:

physics: BouncingScrollPhysics(),

Instead of setting physics parameter you can also use ScrollBehavior

class CustomScrollBehavior extends ScrollBehavior {
 const CustomScrollBehavior();
 @override
 ScrollPhysics getScrollPhysics(BuildContext context) {
 return const BouncingScrollPhysics();
 }
}
ScrollConfiguration(
 behavior: CustomScrollBehavior(),
 child: ListView.builder(
 // physics: BouncingScrollPhysics(),
 itemBuilder: (ctx, index) {
 ...

• iDecode: I already tried this (before posting question), it didn't work.
• Nik: This should work. Might be cache or full restart requires. Have you checked with ScrollConfiguration?
• iDecode: That is basically doing the same thing and hence it also didn't work :(
