Is there a way to load async data on InitState method?

Yes, you can load asynchronous data in the initState method. To do this, you can make use of the Future API in Dart.

Here’s an example:

@override
void initState() {
  super.initState();
  _loadData().then((value) {
    setState(() {
      // Update the state with the loaded data
    });
  });
}

Future<void> _loadData() async {
  // Load the data asynchronously
  final data = await someAsyncDataLoadingFunction();

  // Return the loaded data
  return data;
}

In this example, the _loadData function loads the data asynchronously and returns a Future. The initState method calls this function and waits for it to complete using the await keyword. Once the data is loaded, the setState method is called to update the state with the loaded data.

Note that the initState method should be kept as fast as possible, so it’s recommended to perform only quick operations in it. If you need to perform a long-running operation, it’s better to do it in another method and call it from initState instead.
