marker_motion 0.1.5

A flutter package that smoothly animates Google Maps markers between two positions

0.1.5

This release improves marker animation stability on Android when using MotionImplementation.timer.

• Reworked timer-mode updates to use a frame-synced ticker instead of Timer.periodic, which helps reduce visible marker flicker.
• Kept marker appearance stable while it moves by only animating position during the transition (instead of reapplying all marker properties every frame).
• Applied the latest full marker data once movement completes so non-position updates still land correctly.

0.1.4

This release focuses on making marker updates more efficient and the package more reliable.

• Improved marker update performance by replacing repeated linear marker lookups with fast marker-id map lookups in both animation implementations.
• Reduced per-frame overhead in timer mode by removing debug logging during animation ticks.
• Ensured timer mode correctly respects MarkerMotionConfig.frameRate from MarkerMotion.
• Hardened timer step calculation for very short durations to avoid edge-case timing issues.
• Greatly expanded and refactored the test suite:
  • Added comprehensive behavior tests for animation and timer implementations, including no-op updates, add/remove flows, mid-flight retargeting, empty transitions, rapid updates, remove/re-add flows, tiny delta movements, and dispose safety.
  • Added implementation-specific tests for animation curve/duration updates and timer frame-rate behavior/cancellation.
  • Added configuration assertion tests for invalid MarkerMotionConfig combinations.
  • Simplified test structure with shared helpers and table-driven coverage to improve readability and maintainability.

0.1.3

• Make sure that the frame rate is between 1 - 120 (inclusive).
• Update the README

0.1.2

Fixed formatting.

0.1.1

Reformatted code for pub points.

0.1.0

Initial release of the marker_motion package. Using the MarkerMotion widget you can animate multiple markers on a GoogleMap widget between two positions. It also allows you to choose the underlying implementation to use either an AnimationController driven animation, or a simpler Timer based one.
