ZXing-Dart
A Dart port of zxing that encode and decode multiple 1D/2D barcodes, Supported qrcode, pdf417, oned, maxicode, datamatrix, aztec.
ZXing Widget
ZXing Scanner
Why
Pure Dart implementation, no need to rely on native packages, good platform compatibility
Provide pure Dart encoding for all platforms
Provide pure Dart decoding for all platforms
Research learning and an exploration of Dart language
... At present, this package is far inferior to other native packages in decoding speed and accuracy, and can be used as a decoding tool and some platforms (such as Web and Desktop). I will also continue to pay attention to the improvement of zxing and the improvement of the performance problems in this project. And welcome suggestions for improvement from those with experience in decoding algorithms and image algorithms.
Feature
✅ Core package translate
✅ Core test translate
✅ Core unit test(all passed)
✅ Demo Creator
✅ Demo Scanner (Decode from Captured picture or CameraImage from camera stream)
✅ Code optimization
🚧 Keep syncing from zxing java...
Preview
Demo App
Exception Type
IllegalArgumentException => ArgumentError
FormatException => FormatsException
IllegalStateException => StateError
Issue
Because there is no float type in dart, the results of some test cases are different from zxing
Flutter
This project is a starting point for a Dart
package,
a library module containing code that can be shared easily across
multiple Flutter or Dart projects.
