Question

所以我有这个功能所以注册电话认证：

Future<AuthResults?> authenticateWithPhoneNumber({
  required BuildContext context,
  required Widget navigateTo,
  required String number
}) async {
  try {
    await _firebaseAuth.verifyPhoneNumber(
      phoneNumber: '+33$number',
      timeout: const Duration(minutes: 2),
      verificationCompleted: (PhoneAuthCredential credentials) async {
        await _firebaseAuth.signInWithCredential(credentials);

        navigate(
          context,
          navigateTo
        );
      },
      verificationFailed: (FirebaseAuthException err) { // errors go here. why can't I catch it???
        print('failed');
        throw FirebaseAuthException(code: err.message ?? 'Something went wrong');
      },
      codeSent: (String verificationId, int? resendToken) {
        navigate(
          context,
          VerifyCode(
            verificationId: verificationId,
            resendToken: resendToken
          )
        );
      },
      codeAutoRetrievalTimeout: (String verificationId) {}
    );
  } on FirebaseAuthException catch (err) { 
    print('here'); // never gets executed
    // return AuthResults(
    //   success: false,
    //   error: true,
    //   message: err.message ?? 'Something went wrong...'
    // );
  }
}

我完全不知道这里发生了什么。即使没有指定异常类型的简单 ... catch (err) ... 也不起作用......

由于我无法捕获异常，因此在控制台中出现此错误：

我想我抛出错误的方式有问题...

我认为catch永远不会被调用，但是你可以处理verificationFailed回调中的错误

并删除throw异常

Flutter - 无法捕获 Firebase 身份验证异常
