RASegmentedSwitch class
A TabBar-based segmented switch with a pill-style indicator.
This widget provides a tab interface similar to the standard TabBar but styled as a segmented switch with rounded pill indicators. The TabBar becomes scrollable when there are more than 4 items, otherwise it's fixed. Supports icons, different sizes, and all UISegmentedSwitchItem features.
Example usage:
RASegmentedSwitch(
items: [
RASegmentedSwitchItem(
label: 'Table View',
leftIcon: Icons.list_alt_rounded
),
RASegmentedSwitchItem(
label: 'Home View',
leftIcon: Icons.home
),
],
onTap: (index) {
// Handle tab selection
},
initialIndex: 0,
size: RASegmentedSwitchSize.medium,
)
