CupertinoButton does not handle VoiceOver taps correctly on iOS #170348
Description
Steps to reproduce
- Create a project using
flutter create(Flutter version 3.32.2 in my case) - Edit
main.dartChange from FloatingActionButton to CupertinoButton, remove tooltip property and import 'package:flutter/cupertino.dart' - Run on iOS device, enable VoiceOver and attempt to click the button with a double tap.
Expected results
I expect the button to be pressed and increment the number as per the default flutter app
Actual results
The button appears to get pressed by a double tap but the onPressed function is never called. A triple tap (long press equivalent) does technically work but is the incorrect way to activate the button.
Code sample
Code sample
import 'package:flutter/cupertino.dart';
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(
colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
),
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> {
int _counter = 0;
void _incrementCounter() {
setState(() {
_counter++;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
backgroundColor: Theme.of(context).colorScheme.inversePrimary,
title: Text(widget.title),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
const Text('You have pushed the button this many times:'),
Text(
'$_counter',
style: Theme.of(context).textTheme.headlineMedium,
),
],
),
),
// This is the default app with the comments removed and the FloatingActionButton replaced with a CupertinoButton
floatingActionButton: CupertinoButton(
onPressed: _incrementCounter,
child: const Icon(Icons.add),
),
);
}

If I comment out lines 377 and 379 from the cupertino button file https://github.com/flutter/flutter/blob/flutter-3.32-candidate.0/packages/flutter/lib/src/cupertino/button.dart#L377 then it all works as expected, so it may be a clue :)

This seems like a serious issue, will need more investigation to see what is going on
