我已经在使用AndroidX，并且已经在Firebase中注册了我的应用程序。 Firebase Auth（尝试过Google登录和电子邮件登录/注册）可以工作，但是当我在firebase_database: ^3.1.6中添加pubspec.yaml时，我遇到了这类错误。
我还尝试将firebase_database的版本降级为3.1.0，但没有用
app/build.gradle中的依赖项：

dependencies {
    // implementation 'com.google.firebase:firebase-analytics:17.2.2'
    implementation 'com.google.firebase:firebase-database:19.3.1'
    implementation 'com.google.firebase:firebase-auth:19.3.2'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

compileSdkVersion和targetSdkVersion设置为28
使用的Firebase插件

firebase_auth: ^0.16.1
firebase_database: ^3.1.6
firebase_core: ^0.4.5

编辑：- flutter clean和flutter pub get也不起作用。

任务'：firebase_database：compileDebugJavaWithJavac'的执行失败
