🌟 Summary

This PR introduces numerous improvements to the YOLO Flutter app, including camera handling updates, dependency upgrades, and enhanced method handling for smoother object detection and camera operations.

📊 Key Changes

• Camera Handling:

  • Fixed camera toggle logic to properly handle binding/unbinding for smooth switching between front and back cameras.
  • Refactored camera switching and added safeguards, ensuring robust operations (isSwitchingCamera added for preventing race conditions).
  • Improved iOS camera setup and switching, allowing seamless transitions between camera directions with clear debug logs.

• Codebase Refactor & Debugging:

  • Added detailed debug logs throughout the app for troubleshooting critical operations (e.g., permission checks, model loading, camera setup).
  • Simplified and structured code for better readability (switch-case improvements in method handlers on iOS).

• Dependency Updates:

  • Updated app dependencies such as permission_handler_apple, leak_tracker, and development tools, resolving known issues and improving compatibility.

• iOS Improvements:

  • Reworked iOS camera-related code to handle tasks like video frame capture, switching cameras, and loading machine learning models asynchronously.
  • Added structured handling for video streams, device access, and UI updates to improve performance and stability.

🎯 Purpose & Impact

• Improved Camera Operations: Ensures bug-free handling of camera toggling, reducing crashes and errors for users.
• Enhanced User Experience: Updates to permission handling, loading models, and debug errors prevent app freezes or failures, ensuring smooth app operation.
• Better Maintainability: Refactored and organized code simplifies future iterations and debugging, reducing developer effort.
• Future Compatibility: Dependency updates and platform-related improvements ensure continued compatibility with the latest Flutter and iOS versions.

🚀 These updates will smoothen the object detection workflow, making the app more robust and user-friendly! 😊

@asabri97
The bounding box is misaligned when switching to the front camera.
We need to revise the bounding box code for the front camera so that it surrounds the detected object.
