LiquidScrollPadding class

A zero-friction wrapper widget that automatically reserves bottom space for a LiquidTabBar when used with extendBody: true.

When wrapping a scrollable (e.g. ListView, GridView, or CustomScrollView), LiquidScrollPadding updates the MediaQuery for its descendants with the correct bottom padding computed via LiquidTabBar.reservedHeight.

Examples

Wrapping a scrollable:

LiquidScrollPadding(
  child: ListView.builder(...),
)

Using a spacer at the end of a Column or ListView:

Column(
  children: [
    ...content,
    LiquidScrollPadding.spacer(context),
  ],
)
