ActionCell.chain constructor

ActionCell.chain(ValueCell<void> cell, { dynamic key, required void action(), })

Create an action cell chained to another cell.

This constructor creates an action cell that when triggered by trigger, the function action is called. action has the option of either calling trigger on cell. If action calls trigger the observers of both cell and the returned cell are notified. If action does not call trigger, neither the observers of cell nor the returned cell are notified, effectively preventing the action from taking place.

When the observers of cell are notified, by calling trigger on cell directly, the observers of the returned cell are also notified.

The cell is identified by key if it is non-null.

Implementation

factory ActionCell.chain(ValueCell<void> cell, {
  dynamic key,
  required void Function() action
}) = _ChainedActionCell;
