Use case

For desktop support, it would be nice to have an easy way to configure a splash screen or a window background color (visible before Flutter first frame is rendered).

Proposal

Add properties in c++ code (win32_flutter_window.cc, flutter_glfw.cc, etc) or in a configuration file to make this customizable on desktop launchers.

Launching Flutter on desktop is in early stage and is moving fast so feel free to close this feature request if it is too soon to ask for this.
