SafetyNet认证失败Flutter Firebase Phone认证

Question

我正在研究我的一个扑动项目，并试图添加firebase电话身份验证，但我遇到了与安全网相关的错误。而我能够使用其他身份验证方法，例如SignInWithEmailAndPassword。每当我调用我的phonellogin函数，我得到的错误。我已经在模拟器上安装了google play服务。

Future phoneLogin(String phone) async {
BuildContext context;
try {
await auth.verifyPhoneNumber(
phoneNumber: '+91$phone',
timeout: const Duration(seconds: 30),
verificationCompleted: (PhoneAuthCredential credentials) async {
await auth.signInWithCredential(credentials);
},
verificationFailed: (FirebaseAuthException exception) {},
codeSent: (String verificationId, [int forcedResendingToken]) {
// print('1')
Navigator.push(
context,
MaterialPageRoute(
builder: (BuildContext context) => OtpPage(phone: phone),
),
);
},
codeAutoRetrievalTimeout: (String abc) {});
return null;
} catch (e) {
return null;
}
}

错误

我已经更新了SHA256密钥到我的Firebase控制台。

Answer 1

Firebase已经更新了某些东西，其中之一是他们在发送代码或OTP到移动设备之前包含了captcha验证.

解决方法如下:

将以下内容添加到project/android/app/build.gradle

implementation "androidx.browser:browser:1.3.0"

把这个添加到依赖项部分…

dependencies {
implementation "androidx.browser:browser:1.3.0"
///
}

你可以在这里找到最新的版本:android浏览器。

原因:

应用程序尝试验证captcha并发送代码，因此它尝试启动浏览器，但由于缺少实现，它无法加载浏览器并导致应用程序崩溃。
