我在 app/build.gradle 中做了以下更改

Removed

    implementation 'com.google.android.gms:play-services-vision:20.0.0
    implementation 'com.google.android.gms:play-services-vision:20.0.0'
    implementation 'com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava'

    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'com.google.firebase:firebase-bom:25.12.0'
    implementation 'androidx.annotation:annotation:1.1.0'
    implementation "com.android.support:support-v4:27.1.1"

另外，需要匹配 pubspec.yaml 中的依赖项
