Flutter GetX：传入参数的值在第二页为空

Question

使用 GetX Flutter 从一个页面导航到另一个页面时，从第一页传递的参数不会在第二个页面上接收。

第一控制器：

class LoginController extends GetxController {
  var _loading = false.obs;

  get loading => _loading.value;

  set loading(value) {
    _loading.value = value;
  }

  var _loginResponse = LoginResponse().obs;

  late TextEditingController emailController, passwordController;

  @override
  void onInit() {
    super.onInit();
    emailController = TextEditingController();
    passwordController = TextEditingController();
  }

  @override
  void onReady() {
    super.onReady();
  }

  @override
  void onClose() {
    super.onClose();
    emailController.dispose();
    passwordController.dispose();
  }

  Future<void> loginCall(
      {required String email, required String password}) async {

 
    if (!GetUtils.isEmail(email)) {
      Get.snackbar('Invalid email', 'Please enter valid email',
          snackPosition: SnackPosition.BOTTOM);
      return;
    }

    if (password.length < 8) {
      Get.snackbar('Invalid password', 'Minimum 8 chars',
          snackPosition: SnackPosition.BOTTOM);
      return;
    }

    _loading.value = true;

    var result =
        await NetworkRequest.loginCall(email: email, password: password);

    result != null
        ? _loginResponse.value = result
        : Get.snackbar(
            'Something went wrong', 'Hold back and try again after sometime.',
            snackPosition: SnackPosition.BOTTOM);

    if(_loginResponse.value.responseCode == 1) {

      **Get.offAll(GoogleAuthenticationScreen(), arguments: _loginResponse.value.responseData!.session.toString());**
    }

    _loading.value = false;

  }
}

第二控制器：

class GoogleAuthenticationController extends GetxController {
  var _loading = false.obs;
  late TextEditingController pinController;
  var _authResponse = GoogleTwoFactorResponse().obs;

  @override
  void onInit() {
    super.onInit();
    pinController = TextEditingController();
    var session = Get.arguments.toString();
    twoFactorCall(token: session);
  }

  @override
  void onClose() {
    super.onClose();
    pinController.dispose();
  }

  Future<void> twoFactorCall({required String token}) async {
    _loading.value = true;

    var result = await NetworkRequest.googleAuthentication(token: token);

    result != null
        ? _authResponse.value = result
        : Get.snackbar(
            'Something went wrong', 'Hold back and try again after sometime.',
            snackPosition: SnackPosition.BOTTOM);

    Get.snackbar(result!.responseMessage!, "",
        snackPosition: SnackPosition.BOTTOM);

    _loading.value = false;
  }
}

Getx 版本获取：^4.3.8

Answer 1

你可以试试

 final session = Get.arguments;

在 onInIt 方法之外。希望它会工作
