🌟 Summary (single-line synopsis)

v0.1.45 delivers a critical iOS camera-permission crash fix and strengthens Android camera lifecycle stability, making the Flutter YOLO camera experience far more reliable across real-world navigation and teardown scenarios 📱🛡️

📊 Key Changes

• 🚫 iOS: Prevent fatal crashes when camera permission is denied/unavailable
  • Adds an explicit camera authorization status check before attempting camera setup.
  • Replaces unsafe forced unwrap/error paths (e.g., try!, fatalError) with safe guard + do-catch handling.
  • Makes bestCaptureDevice() nullable and guards camera setup + camera switching logic.
• ⚙️ Android: Reduce dispose/teardown race-condition crashes
  • Introduces a @Volatile isStopped flag and checks it throughout frame processing to avoid accessing released resources during/after stop().
  • Improves shutdown robustness by closing the predictor more safely.
• 🔄 Android: Better camera startup + restart support
  • Adjusts initialization order to set the lifecycle owner before starting camera.
  • Adds a restartCamera method-channel hook, exposed via YOLOViewController.restartCamera().
• 🧪 Example app: More reliable camera restart when navigating back
  • Forces a rebuild when returning to the camera route so the native view is recreated and the camera restarts consistently.
• 📝 Release bookkeeping
  • Updates CHANGELOG.md and bumps plugin version to 0.1.45.

🎯 Purpose & Impact

• ✅ Fewer crashes for end users (especially iOS)
  • Apps no longer hard-crash if a user denies camera permission or if the camera is unavailable. Instead, setup fails gracefully with logs 📵➡️📋
• ✅ More stable real-time inference on Android
  • Prevents intermittent crashes when leaving screens, disposing the view, or stopping inference while frames are still arriving 🧯
• ✅ Smoother navigation and lifecycle behavior
  • Returning to a camera screen is less likely to result in a “stuck” or non-restarting camera thanks to lifecycle ordering + restart support 🔁📷
• ✅ Developer-facing improvement
  • The new restartCamera() hook provides a simple recovery path if the camera needs to be restarted from Flutter (e.g., after permissions change) 🛠️
