Text field undo incorrectly cycles through all composing variants #106473
Description
Steps to Reproduce
- Execute
flutter runon the code sample - Set Japanese IME (this is reproduced on Windows but it should be the same on other OSs)
- Type some text (e.g. "anatano")
- Use key arrows up/down to go through the different IME options, select one
- Press Ctrl+Z to undo
Expected results: A single undo with Ctrl+Z goes back to empty text i.e. during composing, no undo states are stored.
Actual results: Each Ctrl+Z press goes to the previously traversed IME option.
Code sample
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(primarySwatch: Colors.blue),
home: const MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({super.key, required this.title});
final String title;
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text(widget.title)),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: const <Widget>[
Text('Type stuff below'),
Expanded(
child: TextField(maxLines: null),
),
],
),
),
);
}
