clear method

void clear({
  1. bool emitEvent = true,
  2. bool updateParent = true,
})

Removes all children controls from the array.

The value and validity state of the array is updated and the event collectionChanges is triggered.

When updateParent is true or not supplied (the default) each change affects this control and its parent, otherwise only affects to this control.

When emitEvent is true or not supplied (the default), both the statusChanges and valueChanges emit events with the latest status and value when the control is reset. When false, no events are emitted.

Implementation

void clear({bool emitEvent = true, bool updateParent = true}) {
  forEachChild((control) => control.parent = null);
  _controls.clear();
  updateValueAndValidity(
    emitEvent: emitEvent,
    updateParent: updateParent,
  );

  if (emitEvent) {
    emitsCollectionChanged(_controls);
  }
}
