如何在Flutter Dart上将JSON解析为GoogleSignInAccount数据

Question

I want to get JSON data from GoogleSignInAccount.

_googleSignIn.onCurrentUserChanged.listen((GoogleSignInAccount account) async {
  if (account != null) {
    auth = Auth.fromJson(json.decode(account.toString()));
    _signInView.onGoogleResponse(auth);

  } else {
    _signInView.onGoogleResponse(null);
  }
});

but account.toString() returned the response =>

{
 displayName: Mert TUTSAK,
 email: merttutsak@gmail.com
}

I want to return the JSON object.

{
 "displayName": "Mert TUTSAK",
 "email": "merttutsak@gmail.com"
}

How to make it?

Answer 1

What you get is just what toString() produces on a Map .

To get a valid JSON string, use json.Encode() or jsonEncode (they are equivalent)

import 'dart:convert';
...

var json = jsonEncode(account);
print(json);
