Flutter FirebaseAuth未向手机发送验证码

Question

我正在尝试在我的应用程序上添加一个功能，允许用户通过向他们的电话号码发送代码来验证他们的电话号。我发现我可以通过使用firebase来做到这一点。这就是我发送验证码的方式：

Future<void> verifyPhone() async {
void verificationCompleted(AuthCredential phoneAuthCredential) {
print('verificationCompleted $phoneAuthCredential');
_phoneAuthCredential = phoneAuthCredential;
_db.updateUserField(userUid, {
'isNumberConfirmed': true,
'linkedAccounts': FieldValue.arrayUnion(['P-$phoneAuthCredential'])
});
currentUser.isNumberConfirmed = true;
currentUser.linkedAccounts.add('P-$phoneAuthCredential');
worked = true;
}
void verificationFailed(FirebaseAuthException error) {
worked = false;
}
void codeSent(String verificationId, [int code]) {
_code = code;
_verificationId = verificationId;
print('Code: $codet_verificationId: $_verificationId');
}
void codeAutoRetrievalTimeout(String verificationId) {
worked = false;
}
_auth.verifyPhoneNumber(
phoneNumber: '+1${currentUser.phone}',
timeout: Duration(milliseconds: 60000),
verificationCompleted: verificationCompleted,
verificationFailed: verificationFailed,
codeSent: codeSent,
codeAutoRetrievalTimeout: codeAutoRetrievalTimeout);

}

但是每当调用这个方法时，我都会收到以下消息，并且没有发送验证码：

I/BiChannelGoogleApi(25924): [FirebaseAuth: ] getGoogleApiForMethod() returned Gms: com.google.firebase.auth.api.internal.zzao@bafccce
W/DynamiteModule(25924): Local module descriptor class for com.google.firebase.auth not found.
I/FirebaseAuth(25924): [FirebaseAuth:] Preparing to create service connection to gms implementation

我不知道它为什么不发送代码。我是不是错过了什么？

我发现你的代码很难调试，所以我分享了这个：

首先确保您在firebase控制台中启用了电话登录方法，并在pubspec.yaml中添加了Firebase认证插件和Firebase核心插件

定义您的验证电话号码按钮如下：

onPressed: (){
//code for sign in
final mobile = _phoneTextBoxController.text.trim();
registerUser(mobile, context);
}

现在定义整个验证过程如下：

Future registerUser(String mobile, BuildContext context) async{
FirebaseAuth _auth = FirebaseAuth.instance;

_auth.verifyPhoneNumber(
phoneNumber: mobile,
timeout: Duration(seconds: 60),
verificationCompleted: (AuthCredential authCredential){
_auth.signInWithCredential(_credential).then((AuthResult result){
Navigator.pushReplacement(context, MaterialPageRoute(
builder: (context) => HomeScreen(result.user)
));
}).catchError((e){
print(e);
});
},
verificationFailed: (AuthException authException){
print(authException.message);
},
codeSent:(String verificationId, [int forceResendingToken]){
//show dialog to take input from the user
showDialog(
context: context,
barrierDismissible: false,
builder: (context) => AlertDialog(
title: Text("Enter SMS Code"),
content: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
TextField(
controller: _codeController,
),
],
),
actions: <Widget>[
FlatButton(
child: Text("Done"),
textColor: Colors.white,
color: Colors.redAccent,
onPressed: () {
FirebaseAuth auth = FirebaseAuth.instance;

smsCode = _codeController.text.trim();

_credential = PhoneAuthProvider.getCredential(verificationId: verificationId, smsCode: smsCode);
auth.signInWithCredential(_credential).then((AuthResult result){
Navigator.pushReplacement(context, MaterialPageRoute(
builder: (context) => HomeScreen(result.user)
));
}).catchError((e){
print(e);
});
},
)
],
)
);
},
codeAutoRetrievalTimeout: (String verificationId){
verificationId = verificationId;
print(verificationId);
print("Timout");
}
);

那么上面的代码是干什么的呢？首先，它将OTP代码发送给用户，并尝试使用以下代码登录：

verificationCompleted: (AuthCredential authCredential){
_auth.signInWithCredential(_credential).then((AuthResult result){
Navigator.pushReplacement(context, MaterialPageRoute(
builder: (context) => HomeScreen(result.user)
));
}).catchError((e){
print(e);
});
},

并将用户推送到主屏幕，您可以相应地更改上面的代码以匹配您的应用程序主屏幕。如果自动检索失败，则codeSent :向用户显示showDialog以手动输入代码。有关更多信息，请访问这篇媒体文章，有关完整代码，请访问github存储库
