Accessible segmented control (iOS) and "top" tab bar (Android) for Flutter.

This plugin provides an accessible native UISegmentedControl on iOS, and TabLayout on Android (in contrast to my native_tab_bar plugin, which provides a bottom navigation tab bar).

This component is often used for top-of-page navigation. The Flutter "equivalents" are the CupertinoSegmentedControl and TabBar components.

Accessibility problems solved

Due to limitations imposed by Apple and Google in their accessibility APIs, the Flutter engine cannot currently replicate true native accessibility behavior in these components, because their "traits" are only available using the native view classes (Flutter has its own rendering engine and does not instantiate native view classes for every single type of component).

For example, the Flutter components attempt to mimic the native ones by adding the word "button" and the index of the segment ("1 of 3", etc.) to the accessibility label, which is incorrect behavior, because:

  • Braille display users expect shorthand traits such as "button" and list item numbering, because Braille displays are expensive and have a limited number of columns (usually 40 or fewer).

  • Voice Control/Voice Access users need to be able to "tap" the buttons with their voice, using only the button label, without having to speak the title plus "button 2 of 3."

  • When navigating word by word, VoiceOver and TalkBack users expect just the button title to be read, not also the word, "button," or "2 of 3," etc.

Usage Example

Please see example/lib/main.dart for a full usage example.

class HomePage extends StatefulWidget {
  const HomePage({super.key});

  State<HomePage> createState() => _HomePageState();

class _HomePageState extends State<HomePage> {
  int currentTabIndex = 0;

  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('NativeSegments Example')),
      body: Column(
        mainAxisAlignment: MainAxisAlignment.start,
        children: [
            onValueChanged: (value) {
              print("#1 CHANGED VALUE: ${value}");
            segments: List<NativeSegment>[
              NativeSegment(title: 'first'),
              NativeSegment(title: 'second segment long text'),
              NativeSegment(title: 'third segment'),
            style: NativeSegmentsStyle(
              backgroundColor: Colors.transparent,
              isDarkTheme: false,
              selectedSegmentColor: kPrimaryBlue,
