Dynamsoft Barcode Reader Flutter SDK - Release Notes

11.2.3000 (11/06/2025)

🎉Milestone Release

Version 11.2.3000 introduces a series of AI-driven improvements designed to enhance barcode detection accuracy, processing speed, and configuration flexibility.

This release focuses on practical performance gains for production environments across retail, logistics, manufacturing, and identity verification workflows.

✨ Key Highlights

AI-Powered Barcode Detection and Decoding

• New Localization Models – Introduces OneDLocalization and DataMatrixQRCodeLocalization neural network models for improved detection of blurred / low-resolution 1D codes, or partially damaged DataMatrix/QR codes.
• Specialized Decoders – Adds EAN13Decoder and Code128Decoder models optimized for long-distance and motion-blurred decoding scenarios.
• Redesigned Deblur Model – The OneDDeblur model now provides more effective recovery from motion and focus blur.
• Configurable Model Selection – The new ModelNameArray parameter supports flexible model loading and fine-grained control for specific barcode types.

Precision and Processing Control

• Enhanced Deblur Methods – DM_DEEP_ANALYSIS now includes sub-level control with OneDGeneral, TwoDGeneral, and EAN13Enhanced options.
• Barcode Count Expectation – The new ExpectedBarcodesCount parameter enables format-specific quantity control and early termination in fixed-count workflows.
• Improved Region Detection – The new RPM_GRAY_CONSISTENCY mode provides more precise region extraction based on grayscale uniformity and local consistency for document and label processing.

Performance Highlights

Barcode Workflows

• Up to 26.5% higher read rates under blur conditions with as much as 44% faster processing.
• Reliable decoding of DataMatrix and QR codes with missing or damaged finder patterns.
• Extended operational range beyond 75 cm for long-distance barcode scanning.

Developer Notes

• Backward Compatibility – Fully compatible with existing integrations; no code-level changes required for upgrade.
• Configuration Flexibility – Expanded parameter set allows comprehensive model configuration for scenario-specific tuning.
• Production Stability – All new models validated in enterprise environments.

New

• Added a new method, switchCapturingTemplate, which allows switching templates dynamically during the image processing workflow.
• Added a new method, clearDLModelBuffers, to release memory by clearing buffered deep learning models.
• Added a new method, setGlobalIntraOpNumThreads, to configure the global number of threads used for model execution.
• Added barcode details classes:
  • AztecDetails
  • DataMatrixDetails
  • OneDCodeDetails
  • QRCodeDetails
  • PDF417Details
• Added a new button, cameraToggleButton, to the CameraView, allowing users to switch between the front and back cameras. The following APIs are provided for configuring the cameraToggleButton:
  • cameraToggleButton
  • cameraToggleButtonVisible
• Added new methods to class ImageIO for reading and saving images:
  • readFromMemory
  • saveToMemory
• Added a new method cropAndDeskewImage to class ImageProcessor for cropping & deskewing images.

Deprecated

• Deprecated ImageManager class - Use the new ImageProcessor, ImageDrawer, and ImageIO classes instead

11.0.5200 (08/18/2025)

Highlights

• Workflow Improvements
  • Restructured the parameter control hierarchy at all levels for finer scope definition and more granular process management, with the stage level newly added.
  • Enabled custom combinations and sequences of sections, increasing flexibility and operational customization under specific conditions.
• Deep Learning Integration
  • Improved the reading rate of 1D barcode by introducing a new deblurring deep-learning model.
• Algorithm Enhancements
  • Enabled deduplication at the Region of Interest (ROI) level to consolidate results from multiple tasks.
  • Improved the CODE_128 and DataMatrix DeepAnalysis algorithms for better decoding accuracy and performance.
  • Added support for new barcode types: CODE_32, MATRIX_25, KIX, and TELEPEN.
  • Added GS1 Application Identifiers (AI) support for improved code parsing capabilities.
• Engineering Optimizations
  • Unified template-loading logic to reduce I/O overhead.
  • Implemented conversion functionality between ImageData and image files, including both on-disk and in-memory files.

Fixed

• Fixed an xcframework signature issue.
