How to avoid using await key in dart Map by foreach function

Question

So, I have a map which has to do with some asynchronous processing using the items inside. I used the forEach loop construct and inside the callback is designed to be async because I call an await inside the iteration body

myMap.forEach((a, b) { await myAsyncFunc(); } );
callFunc();

I need the callFunc() to be called after all the items have been iterated. But the forEach exits immediately. Help!

Answer 1

You can also use Future.forEach with a map like this :

await Future.forEach(myMap.entries, (MapEntry entry) async {
  await myAsyncFunc();          
});
callFunc();

Answer 2

You could also use map like:

const futures = myMap.map((a, b) => myAsyncFunc());
await Future.wait(futures);
callFunc();
