Usage
To use this plugin :
- add the dependency to your
pubspec.yamlfile:
dependencies:
flutter:
sdk: flutter
flutter_mobile_vision: ^0.1.3
- 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;
}));
}
Barcode
//...
List<Barcode> 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.'));
}
//...
