updateValue method

@override void updateValue(T? value, { bool? onlySelf, bool? emitEvent, bool? emitModelToViewChange, String? rawValue, })

Set the value of the control to value.

If onlySelf is true, this change will only affect the validation of this Control and not its parent component. This defaults to false.

If emitEvent is true, this change will cause a valueChanges event on the Control to be emitted. This defaults to true.

If emitModelToViewChange is true, the view will be notified about the new value via an onChange event. This is the default behavior if emitModelToViewChange is not specified.

Implementation

@override
void updateValue(T? value,
    {bool? onlySelf,
    bool? emitEvent,
    bool? emitModelToViewChange,
    String? rawValue}) {
  emitModelToViewChange ??= true;
  _value = value;
  _rawValue = rawValue;
  if (_onChange != null && emitModelToViewChange) _onChange!(_value);
  updateValueAndValidity(onlySelf: onlySelf, emitEvent: emitEvent);
}
