如何获取设备信息并将其传递到存储库

Question

在这里我想获取设备信息，并在获取设备信息后将其传递到我的存储库文件中，以便每当我注册设备信息时都自动保存。

在此代码中，我想在deviceinfo中传递设备信息。

这是我尝试过的一些代码

class SignupRepository {
  SignupRepository();

  Future<SignupUser> signupUser(Map<String, dynamic> signUpUserMap) async {
    Map<String, dynamic> signupUserRequestMap = {
      "user": {
        "email": signUpUserMap['email'],
        "password": signUpUserMap['password'],
        "mobile": "+918460666940",
        "statusId": "confirmation_pending",
        "profile": {"firstName": "Dipak", "lastName": "Savaliya"},
        "install": {
          "os": "iOS 11.3",

//Here i want to pass device info from device info class

          "deviceInfo": {"device": "iPhone 7 Plus", "manufacture": "Apple"},
          "deviceToken": "34214324213413423421",
          "fcmToken": "1234234234231423421423424234123"
        }
      }
    };
    final QueryResult result = await GraphQLHelper.gqlMutation(
        GQLStrings.signupUser(), signupUserRequestMap);

    SignupUser signupUser = SignupUser.fromJson(result.data);
    return signupUser;
  }


}

这是获取设备信息的代码。当我运行此代码时，它将向我显示所有完美的设备信息。但是我需要在我的存储库类中传递此设备信息（存储库类代码如上所示）

class _DeviceinfoState extends State<Deviceinfo> {
  static final DeviceInfoPlugin deviceInfoPlugin = new DeviceInfoPlugin();
  Map<String, dynamic> _deviceData = <String, dynamic>{};

  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  Future<Null> initPlatformState() async {
    Map<String, dynamic> deviceData;

    try {
      if (Platform.isAndroid) {
        deviceData = _readAndroidBuildData(await deviceInfoPlugin.androidInfo);
      } else if (Platform.isIOS) {
        deviceData = _readIosDeviceInfo(await deviceInfoPlugin.iosInfo);
      }
    } on PlatformException {
      deviceData = <String, dynamic>{
        'Error:': 'Failed to get platform version.'
      };
    }

    if (!mounted) return;

    setState(() {
      _deviceData = deviceData;
    });
  }

  Map<String, dynamic> _readAndroidBuildData(AndroidDeviceInfo build) {
    return <String, dynamic>{

          shrinkWrap: true,
          children: _deviceData.keys.map((String property) {
            print('${_deviceData[property]}');
            return new Row(
              children: <Widget>[
                new Container(
