@di3663 Your issue occurs when linking the flutter_engine.dll.
Since windows has multiple implementation of GCC, I don't know which C compiler you are using.
Are you using the Golang recommended C compiler ?

go version go1.12.7 windows/386

flutter_engine.dll is 64-bit only, which is why you're getting an unknown format on 32-bit Windows.
