Clicking right arrow key on selection isn't removed and cursor is missing,

[robert-ancell]

Steps to Reproduce

1. Create a Flutter application using a TextField.
2. Run your application.
3. Enter the text "01234" in the the field using the keyboard.
4. Select using the mouse "12".
5. Press the right arrow key.

Expected results:

Selection is removed, cursor is placed between "2" and "3".

Actual results:

Selection is removed, cursor is placed between "3" and "4" (off by one error?).

Note that the left cursor works correctly, and moves to the start of the selection. Tested on Linux.

Hi @robert-ancell
I can't reproduce this on Windows. Can you confirm that the issue persists and provide flutter doctor -v logs?
Thank you

I can't reproduce this on Windows.

Some key handling is done at the embedding level, and thus differs between Windows and Linux.

When testing on latest, selection isn't removed when left arrow or right now and cursor is missing

Code Sample

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Material App',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Material App Bar'),
        ),
        body: Center(
          child: TextField(),
        ),
      ),
    );
  }
}

Update

The cursor is actually missing and selection isn't removed at all
