Complex example with three Futures. The widget will show the loading state until all three Futures complete.
class ExampleWidget extends StatelessWidget {
@override
Widget build(BuildContext context) {
return AsyncBuilder.combine3<String, int, double>(
Future.delayed(const Duration(seconds: 1), () => 'String from the future'),
Future.delayed(const Duration(seconds: 6), () => 42),
Future.delayed(const Duration(seconds: 3), () => 1337.0),
onData: (context, a, b, c) => Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text(a),
Text(b.toString()),
Text(c.toString()),
],
),
);
}
