面临同样的问题。然后我发现我错过了将 Firebase 与 Android 项目集成的一组重要说明：https ://firebase.google.com/docs/android/setup#add_firebase_to_your_app

以下是该文档中对我的案例有所帮助的步骤摘要：

生成google-services.json并将其放入您的android/app/目录。
添加classpath 'com.google.gms:google-services:4.1.0'到buildscript -> dependencies您的根级build.gradle配置部分；添加google()到allprogects -> repositories同一文件的部分。
添加implementation 'com.google.firebase:firebase-core:16.0.3'到dependencies应用模块build.gradle文件的部分；apply plugin: 'com.google.gms.google-services'在同一个文件的最底部添加。
同步和重建。现在它应该可以工作了。

在您android/app/build.gradle添加一个依赖项的另一个实现：

...
dependencies {
    implementation "com.google.firebase:firebase-auth:17.0.0"
    ...
}

所涉及的依赖项可能存在一些问题。

就我而言，在应用程序级别进行以下更改非常有效build.gradle

dependencies{
     implementation 'com.google.firebase:firebase-auth:17.0.0'
     implementation 'com.firebaseui:firebase-ui-database:6.0.2'
     ...
}

更改了最新的 firebase-messaging google 依赖项，并在应用程序 gradle 文件中的同一版本中修改了其他依赖项。现在工作正常

依赖项版本详细信息，您可以在此处参考

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.0-alpha4'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha4'
    implementation 'com.google.firebase:firebase-auth:17.0.0'
    implementation 'com.google.firebase:firebase-messaging:18.0.0'
}

就我而言，我忘记在 MainApplication.java 中评论数据库包

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
        new MainReactPackage(),
            new AsyncStoragePackage(),
            new RNCameraPackage(),
            new VectorIconsPackage(),
            new RNGestureHandlerPackage(),
        new RNFirebasePackage(),
        // add/remove these packages as appropriate
        //new RNFirebaseAdMobPackage(),
        new RNFirebaseAnalyticsPackage(),
        //new RNFirebaseAuthPackage(),

       // new RNFirebaseStoragePackage()
      );

如果您在 Flutter 中遇到此问题，请在您的 android/app/build.gradle 中添加此依赖项。并运行你的 main.dart。无需在 ListView 中添加任何类型的控制器。如果您在该页面上使用列表视图。如果您使用的是 Firebase，请在依赖项中添加此内容。

implementation "com.google.firebase:firebase-auth:19.3.0"

我也遇到过同样的问题。您必须更改 pakage.json 文件中的 react-native-firebase 版本。我从这里找到了解决方案

解决方案1：

android/app/build.gradle在您的文件中添加一个对依赖项的实现。

dependencies {
    implementation "com.google.firebase:firebase-auth:17.0.0"
    ...
}

解决方案2：

生成google-services.json并将其放入您的android/app/目录。

添加classpath 'com.google.gms:google-services:4.1.0'到你的根级 build.gradle 配置的 buildscript -> dependencies 部分，并google()作为第一个条目添加到同一文件的 allprogects -> repositories 部分。

  buildscript {
      repositories {
          google()
          jcenter()
      }
      dependencies {
          ...
          classpath 'com.google.gms:google-services:4.1.0'
      }
  }
  allprojects {
      repositories {
          google()
          ...
      }
  }

添加implementation 'com.google.firebase:firebase-core:16.0.3'到应用程序模块build.gradle文件的依赖项部分并添加apply plugin: 'com.google.gms.google-services'到同一文件的最底部。
```
dependencies {
    ...
    implementation 'com.google.firebase:firebase-core:16.0.3'
} 
apply plugin: 'com.google.gms.google-services'
```
同步和重建。

更新您的 Firebase 库！！！！

例如。如果您的应用程序使用 Firebase 身份验证，Google 为其提供最新版本的文档，请将其粘贴到您的 build.gradle

您的 Firebase 助手在 Android Studio 中添加的库通常较旧。

在 gradle.properties 文件中，尝试添加::
