The main difference between async and async* in Dart is the type of result they return:

• async functions return a Future, representing a single asynchronous result[1][2][3].
• async* functions return a Stream, representing a sequence of asynchronous results[1][2].

Here's a more detailed comparison:

async

• Used for asynchronous operations that return a single result, like making an API request[1][3].
• The function body runs until it reaches an await expression, then pauses until the awaited Future completes[3].
• Returns a Future that completes with the return value of the function[1][3].

Example:

Future<int> doSomeLongTask() async {
  await Future.delayed(Duration(seconds: 1));
  return 42;
}

async*

• Used to create a function that returns a sequence of asynchronous results[1][2].
• The function body runs until it reaches a yield statement, then p...
