tapRegionGroupId property

Object? tapRegionGroupId

Optional tap-region group ID for the dropdown overlay.

When provided, the dropdown's overlay joins this shared region so it can coexist with parent popups that use outside-tap detection. If omitted, the dropdown automatically inherits the nearest PopOverlayTapRegionScope when available, then falls back to its own controller tap-region group.

Implementation

final Object? tapRegionGroupId;
