opencv_dart

OpenCV for Flutter, includes all modules. if videoio and highgui are not reqired, use opencv_core

Important

From v1.3.0, dynamic libraries will be built locally, invoked by flutter during the build. Note: OpenCV SDK (~100M) will be downloaded via FetchContent of cmake, you can set DARTCV_CACHE_DIR environment variable to cache it and avoid downloading it again.

v1.0.4 ~ v1.0.6, libs will be downloaded from Releases automatically.

If you want to setup manually, please set OPENCV_DART_DISABLE_AUTO_BUILD environment variable, e.g., export OPENCV_DART_DISABLE_AUTO_BUILD=1(for Unix-like) or $env:OPENCV_DART_DISABLE_AUTO_BUILD=1(for Windows)

For v1.0.4 and below, make sure run the following setup commands before running your app:

flutter pub add opencv_dart or dart pub add opencv_dart
dart run opencv_dart:setup <platform> --arch <arch>
