Creating and Awaiting Futures

Produce and consume Future values.

A Promise of a Value

A Future represents a value that is not ready yet but will arrive later, like a receipt you redeem when your order is done.

A future is always typed by what it will deliver. A Future<int> promises an int once the async work completes.

Future<int> fetchScore() async {
  return 42;
}
