…ive accuracy, low-battery SLC-only - CMMotionActivity re-arms GPS when stationary (motionActivityWake) - desiredAccuracy relaxes to NearestTenMeters at driving speed with hysteresis (speedAdaptiveAccuracy) - battery <=20% and not charging drops to SLC-only regardless of motion, restores on charge or 25% (lowBatterySlcOnly / lowBatteryThreshold) - locationManagerDidPauseLocationUpdates folds the native pause into stationary mode so pausesLocationUpdatesAutomatically is safe - persisted config decodes field-by-field so plugin upgrades no longer break tracking restore - bump 0.4.0 + changelog

What changed
iOS-native power management matching the Life360 playbook:
CMMotionActivity(walking/running/cycling/automotive) while stationary re-arms continuous GPS immediately instead of waiting for an SLC tick or geofence exit. Raw accelerometer still never wakes GPS. (motionActivityWake, default on)desiredAccuracyrelaxes tokCLLocationAccuracyNearestTenMeters, restoring below 7 m/s (hysteresis avoids flapping at city speeds). (speedAdaptiveAccuracy, default on)lowBatterySlcOnly/lowBatteryThreshold)pausesLocationUpdatesAutomaticallymade safe —locationManagerDidPauseLocationUpdatesnow folds the native pause into the plugin's stationary mode (SLC + exit geofence armed), so streaming resumes on movement. The Dart low/balanced presets already set this flag true; before this change a native pause could silently stall updates until the stillness timeout.LocationServiceConfigdecodes field-by-field with defaults. Previously any new config field made the persisted JSON fail decoding wholesale, silently breaking tracking restore after app termination on plugin upgrades.Version 0.4.0 + changelog. No breaking API changes; new
NativeConfigflags opt out.Follow-up after publish: bump Grid-Mobile to
libre_location: ^0.4.0(caret on 0.x won't resolve 0.4.0 from ^0.3.0).Verification
