ActionPlacementConstraints class final

Shared placement rules for a set of root actions.

These constraints affect placement only. They do not draw a border, create a menu, or require actionIds to be adjacent in the collection's root list.

For example, indivisible constraints over A and C move both roots together while preserving the original A, B, C display order:

declaration:  A  B  C
constraint:   [A-----C]

primary:      A     C       or       B
overflow:        B                 A   C

Constructors

ActionPlacementConstraints({required ActionPlacementConstraintId id, required Iterable<ActionId> actionIds, ActionPlacementSplitPolicy splitPolicy = ActionPlacementSplitPolicy.splittable, ActionPlacement? placementOverride, PrimaryRetentionPriority? retentionPriority}): Creates shared placement rules for actionIds.
ActionPlacementConstraints.fromActions({required ActionPlacementConstraintId id, required Iterable<AdaptiveAction<Object>> actions, ActionPlacementSplitPolicy splitPolicy = ActionPlacementSplitPolicy.splittable, ActionPlacement? placementOverride, PrimaryRetentionPriority? retentionPriority}): Creates a placement relationship from action instances.
