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
