Usage

Example

To use this plugin :

• add the dependency to your pubspec.yaml file:

  dependencies:
    flutter:
      sdk: flutter
    flutter_mobile_vision_2: ^0.1.9

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

@override
void initState() {
  super.initState();
  FlutterMobileVision.start().then((x) => setState(() {}));
}

or for a better implementation:

@override
void initState() {
  super.initState();
  FlutterMobileVision.start().then((previewSizes) => setState(() {
    _previewBarcode = previewSizes[_cameraBarcode].first;
    _previewOcr = previewSizes[_cameraOcr].first;
    _previewFace = previewSizes[_cameraFace].first;
  }));
}

    multiple: _multipleBarcode,
    waitTap: _waitTapBarcode,
    //OPTIONAL: close camera after tap, even if there are no detection.
    //Camera would usually stay on, until there is a valid detection
    forceCloseCameraOnTap: true,
    //OPTIONAL: path to save image to. leave empty if you do not want to save the image
    imagePath: '', //'path/to/file.jpg'
    showText: _showTextBarcode,
    preview: _previewBarcode,
