Add support for SliverOverlapInjector.pinned #91972
Description
The Issue
if a NestedScrollView has a pinned SliverAppBar in its headers, a pinned SliverAppBar in a CustomScrollView in its body and the CustomScrollView takes up enough space to be scrollable, the outer app bar covers the inner one on scroll. The issues persists even with the implementation of SliverOverlapAbsorber and SliverOverlapInjector. It's possible that I've misunderstood how the overlap slivers work, but I followed the example in the docs and I think the problem isn't in my implementation.
Code Sample
import 'package:flutter/material.dart';
void main() => runApp(
MaterialApp(
debugShowCheckedModeBanner: false,
home: App(),
),
);
class App extends StatelessWidget {
const App();
@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.yellow,
body: SafeArea(
child: NestedScrollView(
headerSliverBuilder: (ctx, _) => [
SliverOverlapAbsorber(
handle: NestedScrollView.sliverOverlapAbsorberHandleFor(ctx),
sliver: SliverAppBar(
pinned: true,
toolbarHeight: 50,
collapsedHeight: 50,
expandedHeight: 150,
backgroundColor: Colors.blue,
),
),
],
body: Builder(builder: (ctx) {
return CustomScrollView(
slivers: [
SliverOverlapInjector(
handle: NestedScrollView.sliverOverlapAbsorberHandleFor(ctx),
),
SliverAppBar(
pinned: true,
toolbarHeight: 50,
collapsedHeight: 50,
expandedHeight: 50,
backgroundColor: Colors.pink,
),
SliverFixedExtentList(
delegate: SliverChildBuilderDelegate(
(_, i) => Icon(Icons.done),
childCount: 30,
),
itemExtent: 30,
),
],
);
}),
),
),
);
}
}Expected results:
Shouldn't the inner app bar stick to the bottom of the outer one?
Actual results:
bad.mp4
