Dart Stream class

Streams provide an asynchronous sequence of data . Data sequences include user-generated events and data read from files. You can process a stream using either await for or listen() from the Stream API. Streams provide a way to respond to errors. There are two kinds of streams: single subscription or broadcast.

In flutter, streams are usually used with the StreamBuilder which manages and unsubscribes from a stream for you internally once the widget is destroyed. A good rule to follow is when you subscribe to a stream, keep the Subscription and write the code in the dispose method to call cancel .10 Eyl 2019

Stream: This class represents an asynchronous stream of data . Listeners can subscribe to be notified of the arrival of new data events. EventSink: A sink is like a stream that flows in the opposite direction. Adding data events to an EventSink funnels that data into a connected stream.12 Tem 2020

In Dart, you can make a capacity that returns a Stream, which can emanate a few values while the asynchronous process is active. Assuming you need to construct a widget in Flutter dependent on the snapshots of a Stream, there’s a widget called StreamBuilder . In this blog, we will be Exploring StreamBuilder In Flutter.
