我通过 Firebase 在 Android Studio 中使用电话身份验证，我启用了电话登录并在 Firebase 项目中添加了 SHA-1 和 SHA-256。这是我所有的依赖项：

dependencies {

implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.google.android.material:material:1.2.1'
implementation 'androidx.constraintlayout:constraintlayout:2.0.2'
testImplementation 'junit:junit:4.13.1'
implementation 'com.hbb20:ccp:2.4.0'
implementation 'com.google.firebase:firebase-auth:20.0.0'
implementation 'com.google.firebase:firebase-analytics'
implementation platform('com.google.firebase:firebase-bom:26.0.0')
implementation 'com.google.android.gms:play-services-safetynet:17.0.0'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

这是错误日志：

Flutter 应用 Firebase 电话身份验证错误：

此请求缺少有效的应用程序标识符，这意味着安全网检查和 reCAPTCHA 检查均未成功。

请帮我解决这个问题。
