In some cases we say that a future is completed with another future. This is a short way of stating that the future is completed in the same way, with the same value or error, as the other future once that completes.

(since the returned future does not provide access to these values). The cleanUp function is unused if there is no error. The call to cleanUp should not throw.

The call to cleanUp should not throw. {Function onError}. ) Register callbacks to be called when this future completes. When this future completes with a value, the onValue callback will be called with 29 Aug 2019 When the asynchronous operation starts running then it returns a Future to the calling function. It says, “I'm going to have to wait on some stuff.
