To change the default Icon for a flutter desktop application, you have to replace

For Windows windows/runner/resources/app_icon.ico
For MacOS macos/Runner/Assets.xcassets/AppIcon.appiconset/app_icon_*.png

Note that there are tools that can generate the iconset for macos, for example this online tool.

Title is plateform dependant. for Window have a look in main.cpp

  FlutterWindow window(&run_loop, project);
  Win32Window::Point origin(10, 10);
  Win32Window::Size size(1280, 720);
  if (!window.CreateAndShow(L"Your title", origin, size)) {
    return EXIT_FAILURE;
  }

Title is hard coded !
