Slider onChangeEnd is never called when arrow keys are used. #123315
Description
Steps to Reproduce
- Execute
flutter runon the code sample - Click on the slider so it gains focus
- Use left and right arrow keys to change slider position
- Note that
onChangeEndis never called. Only tested on Windows 10.
Expected results: onChangeEnd should be called at the end of every slider change, regardless how it is triggered. With arrow keys, I would expect onChangeEnd to be called when the arrow key is released.
Actual results: onChangeEnd is never called when the arrow keys are used.
Code sample
import 'package:flutter/material.dart';
void main() => runApp(const SliderApp());
class SliderApp extends StatelessWidget {
const SliderApp({super.key});
@override
Widget build(BuildContext context) {
return const MaterialApp(
home: SliderExample(),
);
}
}
class SliderExample extends StatefulWidget {
const SliderExample({super.key});
@override
State<SliderExample> createState() => _SliderExampleState();
}
class _SliderExampleState extends State<SliderExample> {
double _currentSliderValue = 20;
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: const Text('Slider')),
body: Slider(
value: _currentSliderValue,
max: 100,
divisions: 5,
label: _currentSliderValue.round().toString(),
onChanged: (double value) {
setState(() {
_currentSliderValue = value;
});
},
onChangeEnd: (double value) {
print('onChangeEnd');
},
),
);
}
}
