class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Scaffold(
        body: Center(
          child: Focus(
            onFocusChange: (bool hasFocus) => print(hasFocus),
            child: TextField(
              controller: TextEditingController(),
              textAlign: TextAlign.left,
              decoration: const InputDecoration(hintText: 'sample'),

cc @dkwingsmt looks like it's hitting this assert: https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/services/hardware_keyboard.dart#L421

same issue. Have you found a solution？

Long press will trigger the issue.
The engine will send a repeat event after a key up.

This will happen for 'shift' or 'ctrl' key.
