在我的项目中我遇到了以上的错误有谁能告诉我如何解决这个错误。
我面对的错误是：

错误：useTheme必须在NativeBaseConfigProvider内使用
此错误位于：

in ProductContainer (created by App)
in RCTView (created by View)
in View (created by App)
in App (created by ExpoRoot)
in ExpoRoot
in RCTView (created by View)
in View (created by AppContainer)
in RCTView (created by View)
