v3.0.0

Complete rewrite. See MIGRATION.md to upgrade from 2.x.

  • iOS support (iOS 15+, Swift Package Manager), with the same results as
    Android.
  • New API: YoloModel.load, detectImage, detectFrame, dispose, typed
    Detection results (Rect box, label, confidence, polygon) and
    BoxMapper to draw results on screen.
  • Several models can be loaded at the same time.
  • The model format is detected from the model itself: YOLOv5/v7, v8, v9, v11,
    v12 and NMS-free YOLOv10 / YOLO26. modelVersion is gone.
  • LiteRT 2.3 (CompiledModel API) with CPU, GPU and NPU acceleration and
    automatic fallback to CPU.
  • Correct camera frames on every device: row padding and pixel strides,
    NV21, YUV420 and BGRA, and a per-frame rotation.
  • detectImage applies the EXIF orientation and decodes large photos at the
    size the model needs (no more out-of-memory errors).
  • Letterbox resizing (like Ultralytics) instead of stretching, class-aware NMS
    and correct boxes for non-square models.
  • Segmentation outlines are traced in Dart: OpenCV was removed, the native
    libraries are 16 KB page aligned (Android 15+) and apps are tens of MB
    smaller.
  • Models with int8 inputs/outputs and NCHW inputs are supported.
  • No more crashes when a model is closed or replaced during a detection, and
    no more native memory leaks.
  • The plugin no longer adds camera or storage permissions to your app.
  • The pub.dev package is about 120 KB: the example models stay on GitHub.
  • Requires Flutter 3.41+, Android minSdk 24, iOS 15. On iOS the simulator
    needs an Apple Silicon Mac (LiteRT ships arm64 only); see the README for
    the EXCLUDED_ARCHS setting needed by flutter build ios --simulator.
  • Fixes reported issues: 16 KB page size (#58), app size (#27, #40), live
    detection not working on some phones (#34, #36, #37), segmentation crash
    with empty masks (#39), several models at once (#43), portrait photos
    (#41), NCHW inputs (#37) and iOS support (#8). Asset loading errors now say
    what to check (#44, #51). uint8-input models (#42) are still not supported.
  • Tested with Flutter 3.47.8: unit tests, and integration tests on an
    Android 16 emulator and on an iOS simulator (Xcode 26.6).
