[Google3 Bug]: [Accessibility] RangeSlider does not respond to keyboard focus or interactions #170177
Description
b/421086668
Related (existing) issue: #53958
Help us understand the severity of this issue
- causing severe production issues e.g. malfunctions or data loss
- blocking next binary release
- blocking a client feature launch within a quarter
- nice-to-have but does not block a launch within the next quarter
Steps to reproduce
- Add a RangeSlider to the screen
- Attempt to keyboard-navigate to the range slider
- Attempt to use arrow keys to adjust range-slider values
Expected results
Keyboard-navigating to the RangeSlider should focus one of the "thumbs", including a visual indicator and VoiceOver/screen-reader announcement.
Interacting with the RangeSlider using the keyboard's arrow keys should adjust the value of the currently-selected thumb.
Actual results
Keyboard-navigating to the RangeSlider either does not focus the RangeSlider, or at least does not announce or visually indicate the updated focus.
Interacting with the RangeSlider is impossible to do with the keyboard's arrow keys.
Code sample
Code sample
import 'package:flutter/material.dart';
void main() {
runApp(RangeSliderDemo());
}
class RangeSliderDemo extends StatefulWidget {
@override
State<RangeSliderDemo> createState() => _RangeSliderDemoState();
}
class _RangeSliderDemoState extends State<RangeSliderDemo> {
late RangeValues _rangeValues;
@override
void initState() {
super.initState();
// Make sure the initial range values are within the possible range.
_rangeValues = RangeValues(0, 10);
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: RangeSlider(
min: 0,
max: 10,
values: _rangeValues,
onChanged: (RangeValues values) => setState(() => _rangeValues = values),
),
),
);
}

Thanks for the report. I verified this by running the code on macOS desktop and enabling accessibility, as the issue description mentions keyboard navigation. With keyboard, the slider doesn't move and just switches directly from start point to the end.
