Replaces the done event handler of this subscription.
The handleDone
function is called when the stream closes. The value may be null
, in which case no function is called.
This method replaces the current handler set by the invocation of Stream.listen, by calling asFuture, or by a previous call to onDone.
void onDone(void handleDone());
