The Stream class in Dart
The article discusses the Stream class in Dart, highlighting its differences from the Future class. It explains the concepts of single-subscription and broadcast streams, detailing their characteristics and use cases. Additionally, it provides examples of how to create streams from futures and sequences of futures.
- ▪The Stream class in Dart handles a sequence of events, unlike the Future class which deals with a single event.
- ▪Single-subscription streams allow only one listener and stop generating events when the listener unsubscribes.
- ▪Broadcast streams can have multiple listeners and continue to emit events regardless of whether there are listeners present.
