Dart Future.wait() for multiple futures

Future.wait() is a method in Dart’s async package that allows you to wait for multiple Future objects to complete. It takes a list of Future objects as an argument and returns a new Future that completes when all the input Future objects complete.

Here’s an example of using Future.wait() to wait for multiple Future objects to complete:

import 'dart:async';

Future<void> fetchData() async {
  List<Future> futures = [
    fetchFromAPI1(),
    fetchFromAPI2(),
    fetchFromAPI3(),
  ];

  await Future.wait(futures);
}

Future<void> fetchFromAPI1() async {
  // Make API call and process the response
}

Future<void> fetchFromAPI2() async {
  // Make API call and process the response
}

Future<void> fetchFromAPI3() async {
  // Make API call and process the response
}

In this example, fetchData makes multiple API calls and waits for all the responses to come back. Once all the responses are received, fetchData continues executing its code.
