In your StreamProvider example, you're not returning 10 items in a stream, you're returning a single item that is a List of 10 elements. In other words, had you showed the type of the StreamProvider, it would have been StreamProvider<List<int>>. It would have made more sense to show a StreamProvider<int>, and for that you would need to change your yield to a for-in loop, possibly with a delay to see the stream slowly being dribbled out.

thanks for explaining stateNotifierProvider so well. It took me an hour to practice and learn every detail you explained...

[vishwajeetpatil]

Thanks for the excellent tutorial.

In the StreamProvider example (01:13:52), you are returning a constant list. Adding for loop and delay will be more helpful in understanding the change in the stream.

final streamProvider = StreamProvider((ref) async* {
const int max = 20;
List<int> list = [];

for (int i = 0; i < max; i++) {
await Future.delayed(const Duration(seconds: 1));
list = [...list, i];
yield list;
}
});
