How to wait for forEach to complete with asynchronous callbacks in dart?

2 Min Read

In Dart, you can use the await keyword to wait for an asynchronous operation to complete. To wait for a forEach loop to complete with asynchronous callbacks, you can use the Future class to return a future that completes when all of the asynchronous operations in the loop have completed.

Here’s an example of how you can wait for a forEach loop with asynchronous callbacks to complete in Dart:

Future waitForForEach(List list) async {
  List futures = [];
  list.forEach((item) {
  await Future.wait(futures);

Future handleAsyncOperation(item) async {
  // Perform some asynchronous operation with item
  await Future.delayed(Duration(seconds: 1));

void main() async {
  await waitForForEach([1, 2, 3]);
  print('All operations have completed');

In this example, the waitForForEach function accepts a list and performs an asynchronous operation on each item in the list using the handleAsyncOperation function. The handleAsyncOperation function returns a future that completes after a one-second delay. The forEach loop adds each returned future to a list of futures. Finally, the Future.wait function is used to wait for all of the futures in the list to complete.
