Mastering IoT-Flutter Integration: A Journey Through DiY Smart Device Case Studies
summary
Integrates Flutter with a real Android 10 cash‑register SDK to read barcodes, talk to a card reader and print receipts using method channel and event channel, with the full payment flow working after about one week of integration. Ports Flutter to Raspberry Pi using Flutterpi on Raspberry Pi and controls GPIO (relay, distance sensor) by compiling a C library and generating Dart bindings with FFI + FFI Gen, a process that takes roughly four weeks end‑to‑end but produces a responsive, working system.
