## Usage



[Example](https://github.com/edufolly/flutter_mobile_vision/blob/master/example/lib/main.dart)



To use this plugin :



* add the dependency to your `pubspec.yaml` file:



```yaml

  dependencies:

    flutter:

      sdk: flutter

    flutter_mobile_vision: ^0.1.3

```



* add FlutterMobileVision.start() to initState():



```dart

@override

void initState() {

  super.initState();

  FlutterMobileVision.start().then((x) => setState(() {}));

}

```



or for a better implementation:



```dart

@override

void initState() {

  super.initState();

  FlutterMobileVision.start().then((previewSizes) => setState(() {

    _previewBarcode = previewSizes[_cameraBarcode].first;

    _previewOcr = previewSizes[_cameraOcr].first;

    _previewFace = previewSizes[_cameraFace].first;

  }));

}

```

## Barcode



```dart

//...

List barcodes = [];

try {

  barcodes = await FlutterMobileVision.scan(

    flash: _torchBarcode,

    autoFocus: _autoFocusBarcode,

    formats: _onlyFormatBarcode,

    multiple: _multipleBarcode,

    waitTap: _waitTapBarcode,

    showText: _showTextBarcode,

    preview: _previewBarcode,

    camera: _cameraBarcode,

    fps: 15.0,

  );

} on Exception {

  barcodes.add(new Barcode('Failed to get barcode.'));

}

//...

```



### Android
