On Windows, navigating through text with the arrow keys while holding control behaves slightly differently than other platforms, and Flutter misses this. Windows jumps to the start of the next word in either direction, while other platforms jump to the end of words when moving right and the beginning of words when moving left.

Steps to Reproduce

1. Run the app below on Windows, which is just a TextField with "word word word" in it.
2. Focus the field and put the cursor at the start.
3. Hold the word modifier key (ctrl on Windows, option on Mac) and press the right arrow key.

Expected results: "word |word word"

Actual results: "word| word word"

This is the correct behavior on all other platforms, but not on Windows.

import 'package:flutter/material.dart';
 
void main() {
  runApp(MyApp());
}
 
class MyApp extends StatelessWidget {
  final TextEditingController controller = TextEditingController(text: 'word word word');

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: TextField(
            controller: controller,
          ),
        ),
      ),
    );
  }
}
