markAsDirty method
Marks the control as dirty
.
A control becomes dirty when the control's value is changed through the UI.
When updateParent
is false, mark only this control. When true or not
supplied, marks all direct ancestors. Default is true.
When emitEvent
is true or not supplied (the default), the
statusChanges emit event with the latest status when the control is
mark dirty. When false, no events are emitted.
Implementation
void markAsDirty({bool updateParent = true, bool emitEvent = true}) {
_pristine = false;
if (emitEvent) {
_statusChanges.add(_status);
}
if (updateParent) {
parent?.markAsDirty(updateParent: updateParent, emitEvent: emitEvent);
}
}
