dispose method
Release the resources associated to this ProviderElementBase.
This will be invoked when:
- the provider is using
autoDispose
and it is no-longer used. - the associated ProviderContainer is disposed
On the other hand, this life-cycle will not be executed when a provider rebuilds.
As opposed to runOnDispose, this life-cycle is executed only for the lifetime of this element.
Implementation
@override
void dispose() {
super.dispose();
/// The controller isn't recreated on provider rebuild. So we only close it
/// when the element is destroyed, not on "ref.onDispose".
_streamController.close();
}
