What is the difference between Future, Stream, and async/await?

 

Type	Description	Example
Future	Single value returned in future	Future<int> getData()
Stream	Sequence of values over time	Stream<int> getNumbers()
async/await	Used to handle Futures easily	await getData()

Example:

Stream<int> counter() async* {
  for (int i = 0; i < 5; i++) {
    await Future.delayed(Duration(seconds: 1));
    yield i;
  }
}
