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.
