animated_marker 0.3.0

Animate Google Maps markers smoothly between location updates.

Animated Marker

AnimatedMarker smoothly animates google_maps_flutter markers whenever their position or rotation changes.

Features

• Animate marker movement and rotation automatically.
• Keep non-moving markers separate via staticMarkers.
• Tune motion with AnimationPolicy (duration, curve, maxFps).
• Plug into any GoogleMap via a simple builder.

Usage

AnimatedMarker(
  staticMarkers: staticMarkers,
  animatedMarkers: animatedMarkers,
  animationPolicy: AnimationPolicy(
    duration: const Duration(seconds: 3),
    maxFps: 30,
    curve: Curves.easeOut,
    // Optional: skip interpolation for markers fully outside this viewport.
    viewportBounds: currentMapBounds,
    // Optional (recommended for frequent camera updates):
    // pass bounds via ValueListenable to avoid parent rebuild churn.
    // viewportBoundsListenable: boundsNotifier,
  ),
  builder: (context, markers) {
    return GoogleMap(
      initialCameraPosition: const CameraPosition(
        target: LatLng(37.77483, -122.41942),
        zoom: 13,
      ),
      markers: markers,
    );
  },
);

Use this widget when your marker set is driven by live updates (vehicles, delivery tracking, moving assets, etc.) and you want smooth transitions instead of marker jumps.
