fabExpandsToolbar property

bool fabExpandsToolbar
final

When true (default), an adjacent FAB toggles whole-pill expand/collapse and morphs between large (80) and small (56) sizes.

When false, the pill stays open, the FAB stays at M3EToolbarTokens.fabBaseline (56), and only onFabPressed runs. expanded / onExpandedChanged are ignored. Floating toolbars only.

Implementation

final bool fabExpandsToolbar;
