Supporting asynchronous methods

[jlcool]

AppState.fromJson is an asynchronous method，I can't write it like this. How should I write it?

    var p= Persistor<AppState>(
      storage: FlutterStorage(),
      serializer:  JsonSerializer((j) async {
        return await AppState.fromJson(j);
      }
    ),
    ) ;

How come is it asynchronous? Since it's just serializing, it should be synchronous, and you must do any async actions after loading (such as after doing persistor.load(), which will return the result of the serializer)

[jlcool]

Because I encrypt and decrypt the serialized data, and this encryption and decryption method is asynchronous, I am afraid that the serialized data will be modified, affecting software security.

[Cretezy]

That's supposed to be part of the storage instead. Copy/paste the FlutterStorage and add your encryption there

Well, thank you

No problem! Let me know if you need any help. Feel free to create a package to let others use it too!
