core/input/background_isolate_io library

Real background-isolate implementation using dart:isolate (VM / native).

Contains the worker entry points for head-tracking sensor fusion and WiFi CSI processing. This library is only imported on platforms where dart:isolate exists (see background_isolate.dart).

Classes

BackgroundIsolate

Generic handle to a background worker isolate.

Functions

headTrackingFusionEntry(dynamic mainSendPortArg) → void

Entry point for the background isolate executing head-tracking complementary sensor fusion (IMU gyroscope + accelerometer).

wifiCsiProcessingEntry(dynamic mainSendPortArg) → void

Entry point for the background isolate doing compute-heavy CSI signal processing (OFDM subcarrier analysis for WiFi sensing).
