markAsDisabled method
Disables the control.
This means the control is exempt from validation checks and excluded
from the aggregate value of any parent. Its status is DISABLED
.
If the control has children, all children are also disabled.
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), a statusChanged
event is emitted.
Implementation
void markAsDisabled({bool updateParent = true, bool emitEvent = true}) {
if (disabled) {
return;
}
_errors.clear();
_status = ControlStatus.disabled;
if (emitEvent) {
_statusChanges.add(_status);
}
_updateAncestors(updateParent);
}
