This needs an explicit:

  explicit FlagsUO(web::WebUIIOS* web_ui);

Yes, good catch. Done.

   ~FlagsUI() override;
 
  private:
+  base::WeakPtrFactory<FlagsUI> weak_factory_;
   DISALLOW_COPY_AND_ASSIGN(FlagsUI);
 };
 
-class AppleFlagsUI : public BaseFlagsUI {
- public:
-  explicit AppleFlagsUI(web::WebUIIOS* web_ui);
-  ~AppleFlagsUI() override;
-
- private:
-  DISALLOW_COPY_AND_ASSIGN(AppleFlagsUI);
-};
