The article shows how to integrate Flutter's Pigeon tool into HarmonyOS to automatically generate ETS channel code, enabling Flutter developers to avoid writing native HarmonyOS code by adding the pigeon package, defining an API, running the generation command, and using the generated setup in the HarmonyOS side.
This article details how Enterprise WeChat tackled the challenges of five‑platform UI development by adopting Flutter, describing its multi‑module architecture, hybrid stack engine management, communication via pigeon and dart‑ffi, performance optimizations, tooling, and dynamic‑loading strategies that enabled large‑scale cross‑platform deployment.
Pigeon lets Flutter developers define a single Dart API that automatically generates matching, type‑safe interface code for Android and iOS, eliminating manual method‑channel boilerplate, preventing naming mismatches, and keeping native and Dart implementations synchronized across platforms.
This article provides a comprehensive analysis of Pigeon, a point-based open-source RPC framework used by the company, covering its client-side invoker, server-side provider, call flows, Zookeeper integration, service isolation, and operational features.
