detect_image_edges 1.0.3

A flutter plugin to detect edges of objects, scan paper, detect corner, detect rectangle. It allows cropping of the detected object image and returns the path of the cropped image.

1.0.3

• Android: the flash/torch toggle is now shown on Android 14+ devices too (it was wrongly hidden above API 33); torch toggling is guarded and can't crash the scanner.
• Android: much more robust document/edge detection — automatic (median-based) Canny thresholds that adapt to lighting, removed the destructive pre-threshold, morphological close instead of a heavy dilate, and a stronger corner-selection pass with a frame-area guard.
• Android: fixed a native Mat memory leak in SourceManager (the previous scan's image is now released on each new scan).
• Android: the platform result no longer hangs the Dart Future on an unexpected resultCode.
• Android: safer image save (try/catch, no recycle() on a shared bitmap).
• Android: cleaned up crop-screen rotation — single source of truth (no more divergent rotated/cropped state) and removed a redundant bitmap allocation.
• No change to minSdk (still Android 5.0 / API 21) — uses only existing OpenCV and Kotlin stdlib APIs.

1.0.2

• detectEdge and detectEdgeFromGallery now return false instead of throwing a cast error when the native side returns null (e.g. the user cancels the scan).
• Typed the platform channel calls (invokeMethod<bool>) and added API docs.
• Bumped the iOS podspec version to match.
