I have an existing Flutter application and a Unity AR project. The pathfinding logic (A* - A-Star) is partially implemented but not fully functional or correctly integrated. Current Issues: - The A* pathfinding is not fully implemented or needs refinement - The path is not properly aligned with the environment - The path sometimes goes through restricted areas (e.g., center/field) - The path is not smooth and needs Bezier curve smoothing - The AR visualization is not stable or accurate Required Work: I need a developer to fix and complete both the A* pathfinding logic and the integration between Flutter and Unity so that: 1. User selects a destination in Flutter UI 2. Data is sent to Unity 3. A* generates a correct path 4. Unity opens camera and renders AR navigation path correctly in real-time Requirements: - Strong experience with pathfinding algorithms (A*) - Strong experience with Flutter - Experience integrating Unity as a Library - AR Foundation (ARKit / iOS) - C# scripting in Unity Important: - Improve and complete the existing A* implementation (do not replace it entirely) - Do NOT replace Flutter with Unity UI - The task is integration and fixing the AR + pathfinding issues, not rebuilding the app Testing Requirement: - The final solution must run on my iPhone (iPhone 15 Pro) Deliverables: - Fully working end-to-end flow - Correct A* path (no crossing restricted areas) - Smooth path using Bezier curves - Stable AR visualization - Working iOS build (iPhone compatible) - Demo video showing AR path rendering working on device
