groupId property

Object? groupId

An optional group ID that groups TapRegions together so that they operate as one region. If a tap occurs outside of all group members, then group members that are shown will be hidden.

If the group id is null, then only this region is hit tested.

Contract

Throws an AssertionError if the group id is not null and hideOnTapOutside is not set to FHidePopoverRegion.excludeTarget.

Implementation

final Object? groupId;
