OpenCV and ZXing C++ libraries natively in Flutter with Dart FFI using the camera stream

flutter_camera_processing

This Flutter plugin demonstrates how to use OpenCV and ZXing C++ libraries natively in Flutter with Dart FFI using the camera stream.

App Features

• Uses OpenCV v4.7.0 C++ library to process the camera stream
• Utilizes ZXing v2.0.0 C++ library to scan more than 15 barcode types
• Implements Dart FFI to access the native libraries.
• Utilizes ffigen to generate FFI bindings
• Works on Android and iOS

Building and Running

To build and run the project, follow these steps:

1. Download the required versions of the OpenCV and ZXing libraries and install them.
   Note: The project uses wget to download the libraries from the command line.
   If you're on macOS, you can use Homebrew to install wget:

brew install wget

2. On macOS, run the init.sh script:

sh init.sh

On Windows, run the init_windows.ps1 script:

.\init_windows.ps1

By following these steps, you will have the necessary dependencies installed and the project ready to be built and run on both Android and iOS devices.
