【问题描述】：
我的应用程序中的 firebase 有问题。我正在我的应用程序中使用 firebase 进行 OTP。但是当我尝试发送电话号码时遇到了这个问题：
E/MethodChannel#plugins.flutter.io/firebase_auth(19880): Failed to handle method call

我在 android/app.xml 中添加了 google-services.json。我已经在 android/build.gradle 中添加了这些依赖项，并且还尝试更改不同的版本，但应用程序仅适用于 4.1.0：
dependencies {
classpath 'com.android.tools.build:gradle:3.5.3'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// Add the google services classpath
classpath 'com.google.gms:google-services:4.1.0'
}
在android/app/build.gradle的最后还添加了apply plugin：
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'androidx.annotation:annotation:1.1.0'
implementation 'androidx.localbroadcastmanager:localbroadcastmanager:1.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
implementation 'com.google.firebase:firebase-core:17.0.0'
}
apply plugin: 'com.google.gms.google-services'
这是我的源代码：
void _onVerifyCode() async {
setState(() {
isCodeSent = true;
});
final PhoneVerificationCompleted verificationCompleted =
(AuthCredential phoneAuthCredential) {
_firebaseAuth
.signInWithCredential(phoneAuthCredential)
.then((AuthResult value) {
if (value.user != null) {
// Handle loogged in state
print(value.user.phoneNumber);
Navigator.pushAndRemoveUntil(
context,
MaterialPageRoute(
builder: (context) => HomeWidget(
user: value.user,
),
),
(Route<dynamic> route) => false);
} else {
showToast("Error validating OTP, try again", Colors.red);
}
}).catchError((error) {
showToast("Try again in sometime", Colors.red);
});
};
final PhoneVerificationFailed verificationFailed =
(AuthException authException) {
showToast(authException.message, Colors.red);
setState(() {
isCodeSent = false;
});
};
final PhoneCodeSent codeSent =
(String verificationId, [int forceResendingToken]) async {
_verificationId = verificationId;
setState(() {
_verificationId = verificationId;
});
};
final PhoneCodeAutoRetrievalTimeout codeAutoRetrievalTimeout =
(String verificationId) {
_verificationId = verificationId;
setState(() {
_verificationId = verificationId;
});
};
// TODO: Change country code
await _firebaseAuth.verifyPhoneNumber(
phoneNumber: "+90${widget.mobileNumber}",
timeout: const Duration(seconds: 60),
verificationCompleted: verificationCompleted,
verificationFailed: verificationFailed,
codeSent: codeSent,
codeAutoRetrievalTimeout: codeAutoRetrievalTimeout);
}
void _onFormSubmitted() async {
AuthCredential _authCredential = await PhoneAuthProvider.getCredential(
verificationId: _verificationId, smsCode: _pinEditingController.text);
_firebaseAuth
.signInWithCredential(_authCredential)
.then((AuthResult value) {
if (value.user != null) {
// Handle loogged in state
print(value.user.phoneNumber);
Navigator.pushAndRemoveUntil(
context,
MaterialPageRoute(
builder: (context) => HomeWidget(
user: value.user,
),
),
(Route<dynamic> route) => false);
} else {
showToast("Error validating OTP, try again", Colors.red);
}
}).catchError((error) {
showToast("Something went wrong", Colors.red);
});
}
Flutter clean 效果不佳！
