[Desktop] Directional focus traversal stops working after scrolling ListView

[jpnurmi]

Directional focus traversal stops working when a focused item is scrolled outside the list view's cache extent.

Steps to Reproduce

1. Run the attached example
2. Press TAB to move focus to the list view
3. Press up/down arrows to move focus around
4. Press page up/down a couple of times
5. Press up/down arrows again

Expected results:

The list view is scrolled back to the focused item and focus traversal continues from where it was.

Actual results:

Directional focus traversal no longer works. Nothing happens.

Code sample

import 'package:flutter/material.dart';

void main() {
  runApp(const MaterialApp(home: MyHomePage()));
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key}) : super(key: key);

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  void initState() {
    super.initState();
    FocusManager.instance.addListener(() {
      print('focus changed ${FocusManager.instance.primaryFocus}');
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SizedBox.expand(
        child: ListView.builder(
          itemBuilder: (BuildContext context, int index) {
            return ListTile(
              onTap: () {},
              title: Text(index.toString()),
            );
          },
        ),
      ),
    );
  }
}

Hi @jpnurmi, Thanks for filing the issue. I can reproduce the issue on stable 2.5.2 and the master 2.6.0-12.0.pre.299 channel. After page up/ down the focus doesn't work with arrow keys until the currently focused item is brought into view by either scrolling via mouse / page (up/down)

Screen.Recording.2021-10-13.at.7.42.49.PM.mov

Note: The moment in the video when the scroll is stopped is when I am pressing the arrow keys at 09:00 , 19:00 which doesn't work unless scrolled to focused item

Directional focus traversal no longer works. Nothing happens.

Can you please point the version where it worked in the past it might help to track down the change that affected it.

flutter doctor -v
