@vusarath Hi, any chance you managed to solve this?

If you need to use a plugin within a sub-window, you must manually register it in main.cpp or flutter_window.cpp when the sub-window is created.

The code you provided demonstrates the correct method for this: DesktopMultiWindowSetWindowCreatedCallback([](void *controller) { auto *flutter_controller_sub_ = reinterpret_cast<flutter::FlutterViewController *>(controller); auto *registry = flutter_controller_sub_->engine(); // Manual registration of native plugins for the sub-window WindowManagerPluginRegisterWithRegistrar( registry->GetRegistrarForPlugin("WindowManagerPlugin")); FlutterInappwebviewWindowsPluginCApiRegisterWithRegistrar( registry->GetRegistrarForPlugin("FlutterInappwebviewWindowsPluginCApi")); ScreenRetrieverWindowsPluginCApiRegisterWithRegistrar( registry->GetRegistrarForPlugin("ScreenRetrieverWindowsPluginCApi")); DesktopDropPluginRegisterWithRegistrar( registry->GetRegistrarForPlugin("DesktopDropPlugin")); WebviewWindowsPluginRegisterWithRegistrar( registry->GetRegistrarForPlugin("WebviewWindowsPlugin")); });
