motion_sickness_stabilizer 0.4.1

Reduce motion sickness while using a phone in a moving vehicle — sensor-driven vehicle motion cues (animated dots), an artificial horizon and a focus dot, plus an Android system overlay that floats th [...]

0.4.1

Package renamed.

• Renamed from motion_stabilizer_core to motion_sickness_stabilizer so the package is easier to find. No API changes — update your dependency and import:

  dependencies:
    motion_sickness_stabilizer: ^0.4.1
  

  import 'package:motion_sickness_stabilizer/motion_sickness_stabilizer.dart';
  

• The old motion_stabilizer_core package is discontinued and will receive no further updates.

0.3.0

More customization + fixes.

• Fixed: the horizon no longer spins on a quick shake — tilt is now heavily smoothed via horizonStabilization (0 = raw, 0.85 default, ~0.97 very calm). Uses the device gravity vector, so only sustained tilt rotates it.
• New bubbles options: dotShape (circle/ring/square/diamond), dotSizeJitter (organic per-bubble sizes), dotGlow, a dotReactToMotionOpacity toggle for the brighten-on-motion behaviour, and a center placement so bubbles can fill the middle.
• Water-flow wave: wavy/filledHorizon now use a multi-harmonic travelling wave that flows like water and, with waveReactsToMotion, "dances" with device motion. waveAnimated toggles static vs flowing.
• The native Android overlay mirrors every new option; both layers verified.
• Example app exposes all new controls.

0.2.0

Customization overhaul + visibility fixes.

• Fixed: cues no longer vanish at rest or in the background — base visibility is decoupled from motion. Bubbles ramp from dotBaseOpacity to dotMaxOpacity; the horizon uses a constant dividerOpacity.
• New: independent showDots / showFocusDot toggles, and a dividerStyle with six designs — line, wavy (animated), dashed, dualRail, filledHorizon (light-blue split), gradientBand — plus none.
• New: full styling control (colours, sizes, opacities, wave params) and medically-informed presets gentle(), standard(), intense(), calmHorizon().
• The native Android overlay mirrors every new style and animates continuously.
• Breaking: removed showHorizon/horizonColor/minOpacity/maxOpacity and the HorizonLine widget. Use dividerStyle/dividerColor, dotBaseOpacity/dotMaxOpacity and MotionDivider instead.

0.1.0

Initial release.

• In-app motion cues: MotionStabilizer, MotionOverlay, HorizonLine and FocusDot, driven by a reactive MotionController.
• Sensor fusion via SensorService + MotionFilter (low-pass gravity removal and smoothing) over sensors_plus.
• Android system overlay (BackgroundOverlayService): a foreground service that floats the cues over other apps using SYSTEM_ALERT_WINDOW, with the same motion maths implemented natively in Kotlin.
• Optional Android accessibility-service toggle.
• Shared, serialisable MotionCueConfig for colour, layout, gain and axis handling.
• Example app demonstrating both layers.
