The sample demonstrates how to create a simple Flutter barcode plugin with Dynamsoft Barcode Reader SDK.

Download the source code:

git clone https://github.com/yushulx/flutter-barcode-plugin.git

Get a free 30-day trial license and set it in demo\lib\main.dart:

Future<void> initDynamsoftBarcodeReaderState() async {
    _barcodeReader = BarcodeReader();
    await _barcodeReader.initLicense('LICENSE-KEY');
  }

Read barcodes from an image file:

await _controller.takePicture(path);
String results = await _barcodeReader.decodeFile(path);
