indicatorExpansion property

EdgeInsetsGeometry indicatorExpansion

Expansion padding applied to the active indicator pill during interaction.

The pill grows by this amount beyond its segment boundary as the user drags, creating the iOS 26 "jelly" overshoot. Defaults to EdgeInsets.symmetric(horizontal: 12, vertical: 8) matching GlassBottomBar and GlassTabBar.

Implementation

final EdgeInsetsGeometry indicatorExpansion;
