CharacterActivator not working with hardware keyboard on iOS #99255

Open collinjackson opened 2 years ago

collinjackson commented 2 years ago

Steps to Reproduce

CharacterActivator is not triggered in a Flutter app when using a hardware keyboard connected to an iOS device or simulator. It works on Android.

When testing on physical devices I used an MX Keys keyboard connected via Bluetooth. For the iOS simulator test, I used the built-in keyboard on the host machine.

  1. Execute flutter run on the code sample
  2. Observe the text "Ask a question"
  3. Hold down Shift and press the "/" key to produce the character "?"

Expected results: Screen shows "Good question!" because CharacterActivator triggered.

Actual results: On Android, it works. On iOS, the screen continues to show "Ask a question"

You can edit the code sample to try to detect other characters and it still doesn't work on iOS.

Code sample ```dart import 'package:flutter/material.dart'; void main() { runApp(const MyApp()); } class MyApp extends StatefulWidget { const MyApp({Key? key}) : super(key: key); @override State createState() => _MyAppState(); } class _MyAppState extends State { String _text = "Ask a question"; @override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter Demo', theme: ThemeData( primarySwatch: Colors.blue, ), home: Scaffold( body: Center( child: CallbackShortcuts( bindings: { const CharacterActivator('?'): () { setState(() { _text = "Good question!"; }); }, }, child: Focus( autofocus: true, child: Text(_text, style: const TextStyle(fontSize: 40)), ), ), ), ), ); } } ```
