   Additional notes

   Breaking Changes

   • zxing_lib is no longer part of the public API. The package now owns its models, so consuming apps never need a zxing_lib dependency:
     • decodeFile and decodeCameraImage return ScanResult? instead of zxing_lib's Result?.
     • BarcodeFormat is now this package's own enum, exposing only the formats that are actually supported (aztec, code39, code93, code128, dataMatrix, ean8, ean13, itf, pdf417, qrCode). Unsupported formats are a compile error instead of a runtime exception.
     • export 'package:zxing_lib/zxing.dart' show BarcodeFormat, Result was removed from the barrel.
   • FileDecode.decode, CameraDecode.decode and IsolateCameraDecode.setYuv420Planess return ScanResult?; FileDecodeEvent.formats and IsolateCameraDecode.currentResults use the new types as well.

   Features

   • Added ScanResult with text, format, timestamp, rawBytes and corners.
     • corners is a List<Point<double>> (dart:math), keeping the package pure Dart. Flutter apps can bridge it to Offset with toOffset/toOffsets from package:qr_code_dart_scan.
     • ScanResult keeps identity equality on purpose, so repeated scans of the same barcode still notify.

   Bug Fixes

   • CameraDecode.decode now honours the formats it is given. It accepted the argument but never forwarded it to the reader, so camera decoding was unrestricted and could return a barcode in a format the caller had not asked for.

   Migration

   // Before
   final Result? result = await decoder.decodeFile(bytes);
   result?.barcodeFormat; // zxing_lib BarcodeFormat
   result?.resultPoints;  // List<ResultPoint?>?
   
   // After
   final ScanResult? result = await decoder.decodeFile(bytes);
   result?.format;  // qr_code_dart_decoder BarcodeFormat
   result?.corners; // List<Point<double>>, never null
