Futures
Futures in Flutter are a way of representing a potential value that will be available at some point in the future. Some key points about Futures in Flutter:
- Futures are used for asynchronous programming in Flutter
- Futures return a single value (or an error) and are often used with
asyncandawait. - The
thenmethod can be used to attach a callback to a Future that will be executed once the Future’s value is available - Futures can be combined with other Futures using
Future.waitorFuture.whenCompletemethods - Futures are often used with network requests, file I/O operations, and other long-running tasks in Flutter.
