Ain't going to happen. There is no real support for Go on Android at first place, sure you can compile Go programs on Android , but that's about how useful Go is on that platform. And frankly have you ever tried to write a desktop app with a GUI in Go ? Because you'd know how painful it is.
The app I want to write is basically a service that just does stuff (with files) based on signals from other devices/services. The UI is actually client side webapp. So I was hoping to write the service bit in Go which then would run on Linux, Windows, Mac, Android. Oh well.
Dart can do this already. It works in Server Side just fine (Win, Mac, Linux - x86,Mips, Arm).
Flutter is build on top of the mojo. This exposes IPC interfaces to the devices. There are Java, Dart, C++, and I believe also go bindings for this. Not sure if this is in a usable state - but worth a look.
