So basically rewrite your Electron app in Flutter.
Flutter Desktop is still in beta and the ecosystem is still immature, let alone prehistoric support for the existing Flutter libraries and functionality.
Actually right now Flutter Desktop support is officially in "Alpha" not beta, so sure its immature compared to Electrons ecosystem foro example. But on the other hand, is far more mature than day Jetbrains Compmose Dekstop effort.
But I have no idea what you mean by "prehistoric support" ? Was that a typo?
Also rewrites, especially just to change platform are often a very bad idea. But if you are writing a new app or radically reworking an existing app, using Flutter instead of Electron today would have some merit.
Just another "browser" reboot. To be a standard everybody must accept, as web is portable. If you are only looking for cheap tricks this will happen again and again. Maybe a new language that does flutter,C#,java,javascript interop should be created? then a couple of clones...

Still not ready yet.
