尝试： 使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。运行 --scan 以获得完整的见解。

【问题讨论】：

使缓存失效并从 AS 重新启动

已经做了。但仍然是同样的问题

查看在com.google.android.gms:play-services-vision:20.0.0 和com.google.android.gms:play-services-vision:19.1.0 中发现重复的错误。两者都是一样的，只是版本不同你最近更新依赖了吗？

是的..我已经更新了..但是在使缓存无效并重新启动后它的行为仍然相同..我也看到了同样的错误但无法找到 19.1.0

做flutter clean，如果这没有帮助。去yourAppFolder->android.打开cmd做gradlew clean

【参考方案1】：

我在 app/build.gradle 中做了以下更改

已删除

    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 'com.google.firebase:firebase-dynamic-links:19.0.0'
    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
