Fix the incorrect position of SliverTree child nodes. ( #167928 )
...
Run the code below:
```dart
import 'package:flutter/material.dart';
import 'package:flutter/rendering.dart';
void main() => runApp(const MaterialApp(home: MyApp()));
class MyApp extends StatefulWidget {
const MyApp({super.key});
@override
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
final GlobalKey _key = GlobalKey();
final GlobalKey _childNodeKey = GlobalKey();
late final List<TreeSliverNode<GlobalKey>> tree = [
TreeSliverNode<GlobalKey>(_key, expanded: true, children: [
TreeSliverNode<GlobalKey>(_childNodeKey),
]),
];
@override
Widget build(BuildContext context) {
return Scaffold(
body: CustomScrollView(
slivers: [
TreeSliver(
tree: tree,
indentation: TreeSliverIndentationType.custom(40),
treeRowExtentBuilder: (node, dimensions) => 40,
treeNodeBuilder: (context, node, animationStyle) {
return Container(
key: node.content as Key,
color: node.content == _key ? Colors.blue : Colors.green,
);
},
),
],
),
floatingActionButton: FloatingActionButton(
onPressed: () {
final RenderBox rb = _childNodeKey.currentContext!.findRenderObject() as RenderBox;
print(rb.localToGlobal(Offset.zero));
},
child: const Icon(Icons.add),
),
);
}
}
```
Get the screen:
When the `floatingActionButton` is clicked, it should print the position
of the green `Container`. The expected result is `Offset(40.0, 40.0)`,
but the actual result is `Offset(0.0, 40.0)`. `hitTest` also produces
incorrect results. This PR fixes the issue.
