dart - How to load JSON assets into Flutter App

How do I load a JSON asset into my Flutter app?

My pubspec.yaml file has the following:

  assets:
    - assets/data.json

I keep getting stuck trying to load the data. I tried

final json = JSON.decode(
    DefaultAssetBundle.of(context).loadString("assets/data.json")
);

But I get the error

The argument type 'Future< String>' can't be assigned to the parameter type 'String'.

Thanks!

Try out :

String data = await DefaultAssetBundle.of(context).loadString("assets/data.json");
final jsonResult = jsonDecode(data); //latest Dart
