High‑Accuracy User Behavior Tracking in Flutter for Xianyu
To replace the native‑only tracking used by Xianyu after its migration to Flutter, the team built a high‑accuracy solution that mirrors the Flutter navigation stack with an index list, correctly fires enter/leave events on pushes, pops and filtered dialogs, and adds exposure detection based on 50 % visibility for 500 ms, ultimately delivering 100 % tracking accuracy in production.
