颤振 - 无法捕获 Firebase 身份验证异常

Question

所以我有这个功能，所以用电话身份验证注册：

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。即使有一个简单的... catch (err) ...而不指定Exception类型也不起作用。。。

由于我无法捕捉到异常，我在控制台中收到以下错误：

我想我抛出错误的方式有问题。。。

Answer 1

我认为catch永远不会被调用，但您可以处理verificationFailed回调中的错误

并删除抛出异常
