GopherCon 2025 talk by Andy Williams introducing Fyne, a pure Go framework for building native graphical apps across desktop, mobile, and web from a single codebase. The talk focuses on a new work-in-progress capability: running Fyne apps without an operating system on bare-metal and embedded hardware. A new `SetDriverDetails` API lets developers specify how their device draws to screen and handles events. Live demos show the same Fyne app running inside a QEMU UEFI environment and compiled with TinyGo for embedded devices like a gopher badge, all from one codebase. The presenter also reveals that the slideshow, terminal, and desktop environment used during the talk are themselves Fyne apps.
