clearDrawables method
Removes all drawables from the controller value.
If newAction
is true
, the action is added as an independent action
and can be undone in the future. If it is false
, the action is connected to the
previous action and is merged with it.
Calling this will notify all the listeners of this PainterController that they need to update (it calls notifyListeners). For this reason, this method should only be called between frames, e.g. in response to user actions, not during the build, layout, or paint phases.
Implementation
void clearDrawables({bool newAction = true}) {
final action = ClearDrawablesAction();
action.perform(this);
_addAction(action, newAction);
}
