Could be initialized using the new switch expression:
final double tapTargetVerticalPadding = switch (resolvedTargetSize) {
MaterialTapTargetSize.shrinkWrap => 0,
MaterialTapTargetSize.padded => max(0, kMinInteractiveDimension + densityAdjustment.dy - effectedButtonHeight);
};| expect(state.statesControllers.values.first.value, states); | ||

Might be better to not that the button's height is 40 but its tap target's height is 48. Like:
'Min button hit target height is 48 and min (painted) button height is 40'
| paints..rrect( | ||
| style: PaintingStyle.stroke, | ||
| strokeWidth: 1.0, | ||
| // Button border height is 43.5 - 4.5 + stoke width(1) = 40. |

If 43.5 and 4.5 correspond to something can identify here, then best to include that info in the comment.

fix #121493
SegmentedButtonusesTextButtonfor each segments. When we haveMaterialTapTargetSize.paddedforTextButton, we make sure the minimum tap target size is 48.0( this value can be adjusted by visual density), even tough the actual button size is smaller. WhenSegmentedButtonpaints segments by usingMultiChildRenderObjectWidget, it also includes the tap target size so the button that it actually draws always has the same height as the height of the tap target size.To fix it, this PR firstly calculate the actual height of a text button in
SegmentedButtonclass, then we can get the height delta if there is. Then the the value of (Segmented button render box height - the delta) would be the actual button size that we should see.For now, we are not able to customize the min, max, fixed size in
SegmentedButtonstyle. So the standard button height is always 40 and can only be customized bystyle.visualDensityandstyle.tapTargetSize;SegmentedButtononly simulates theTextButtonbehavior whenTextButton's height is its default value.SegmentedButtonDemo.mov
