# 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](https://github.com/opencv/opencv) C++ library to process the camera stream

- Utilizes [ZXing v2.0.0](https://github.com/zxing-cpp/zxing-cpp) C++ library to scan more than 15 barcode types

- Implements [Dart FFI](https://pub.dev/packages/ffi) to access the native libraries.

- Utilizes [ffigen](https://pub.dev/packages/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](https://brew.sh) to install `wget`:

```sh

brew install wget

```

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

```sh

sh init.sh

```

On Windows, run the init_windows.ps1 script:

```sh

.\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.
