BaseSegmentedControl class
BaseSegmentedControl - Cross-platform segmented control with native iOS support
Uses CNSegmentedControl (Cupertino Native) for iOS - provides true native iOS appearance with built-in liquid glass effects and native rendering. Uses Material SegmentedButton for Android and other platforms.
*** use cupertino = { forceUseMaterial: true } force use SegmentedButton on iOS *** use material = { forceUseCupertino: true } force use CNSegmentedControl on Android
Features:
- Native iOS segmented control via CNSegmentedControl (cupertino_native package)
- Material Design SegmentedButton for Android
- Consistent API across platforms
- Built-in liquid glass effects on iOS (no manual wrapper needed)
Example:
BaseSegmentedControl(
labels: const ['One', 'Two', 'Three'],
selectedIndex: _selectedIndex,
onValueChanged: (i) => setState(() => _selectedIndex = i),
)
Updated: 2024.10.25 - Renamed from BaseCNSegmentedControl for consistency
