[Sanlorng]

Components

1. SegmentedControl
2. SegmentedButton

Issue

we should align the design file? indicator always at center bottom of item text, even if item has icon.

Basic Usage

val checkedIndex = remember { mutableStateOf(0) }
SegmentedControl {
    repeat(count) { index ->
        SegmentedButton(
            checked = index == checkedIndex.value,
            onCheckedChanged = { checkedIndex.value = index },
            position = when (index) {
                0 -> SegmentedItemPosition.Start
                count - 1 -> SegmentedItemPosition.End
                else -> SegmentedItemPosition.Center
            },
            text = { Text("Text") }
        )
    }
}
