In computer science, future, promise, delay, and deferred refer to constructs used for synchronizing program execution in some concurrent programming languages . They describe an object that acts as a proxy for a result that is initially unknown, usually because the computation of its value is not yet complete.
Read moreWhat is a Future class?
Simply put, the Future class represents a future result of an asynchronous computation . This result will eventually appear in the Future after the processing is complete. Let’s see how to write methods that create and return a Future instance.
Read moreWhat is Future and stream in Flutter?
The difference is that Futures are about one-shot request/response (I ask, there is a delay, I get a notification that my Future is ready to collect, and I’m done!) whereas Streams are a continuous series of responses to a single request (I ask, there is a delay, then I keep getting responses until the stream dries up …

Read moreHow do you initialize darts in Future?
To initialize a Future<Type>, see the following example: Future<String> myFutureString = Future(() => “Future String”); Here “Future String” is a String and so the code above returns an instance of Future<String>.
Read moreWhat’s Future in Dart?
What is a future? A future (lower case “f”) is an instance of the Future (capitalized “F”) class . A future represents the result of an asynchronous operation, and can have two states: uncompleted or completed. Note: Uncompleted is a Dart term referring to the state of a future before it has produced a value.
Read moreWhat is Future async?
When an async function is called, a Future is immediately returned and the body of the function is executed later . As the body of the async function is executed, the Future returned by the function call will be completed along with its result. In the above example, calling demo() results in the Future.
