Unleashing Flutter on embedded hardware
summary
Flutter-pi is a lightweight Flutter engine embedder that runs without X11 or Wayland and supports OpenGL ES and Vulkan on constrained boards (example: Toradex AM6254 with 4x A53 and 2 GB RAM). The codebase is about 30,000 lines of C/C++; demos include GPIO on/off, PWM dimming, I²C RTC reads, and CAN/CANopen control of an RGB button pad — all working live with occasional demo glitches. Tooling includes a custom flutterpi-tool for hot reload and a private engine CI that uses ~50 machines for 1.5 hours to produce usable engine binaries for custom embedders.
