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 async and await.
• The then method 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.wait or Future.whenComplete methods
• Futures are often used with network requests, file I/O operations, and other long-running tasks in Flutter.
