AdaptiveAction<T extends Object> class final

An immutable, platform-neutral action node.

A node can carry an invocation payload, children, or both. Renderers decide how to present the node in its resolved region; moving a node never changes or flattens its children. Core never invokes payload. A renderer hands an enabled node's payload back to a caller-owned handler and preserves child navigation as a separate interaction.

Constructors

AdaptiveAction.action({required ActionId id, required ActionMetadata metadata, required T payload, bool isEnabled = true, ActionPlacementPolicy? placementPolicy})
Creates a leaf that invokes payload.
factory
AdaptiveAction.composite({required ActionId id, required ActionMetadata metadata, required T payload, required Iterable<AdaptiveMenuEntry<T>> children, bool isEnabled = true, ActionPlacementPolicy? placementPolicy})
Creates a branch that can both invoke payload and open children.
factory
AdaptiveAction.menu({required ActionId id, required ActionMetadata metadata, required Iterable<AdaptiveMenuEntry<T>> children, bool isEnabled = true, ActionPlacementPolicy? placementPolicy})
Creates a branch that opens children without invoking a payload.
