Dynamsoft MRZ Scanner Flutter SDK - Release Notes

3.4.1300 (05/20/2026)

New

• Image results: MRZScanResult now returns captured images alongside the parsed MRZ data. Three types of images can be retrieved from the result:
  • Document image: A cropped and perspective-corrected image of the document, available via mrzSideDocumentImage and oppositeSideDocumentImage. Returned by default.
  • Original image: The raw full-frame camera image captured at the moment of scanning, available via mrzSideOriginalImage and oppositeSideOriginalImage. Disabled by default.
  • Portrait image: The detected portrait extracted from the document, available via portraitImage. Returned by default.
  • For two-sided ID cards, the MRZ side and opposite side images are available via separate properties on MRZScanResult.
• Image return configuration: Added three new MRZScannerConfig properties to control which images are included in the scan result:
  • returnDocumentImage (default: true)
  • returnOriginalImage (default: false)
  • returnPortraitImage (default: true)
• Additional MRZ data fields: MRZData now exposes the following additional parsed fields:
  • issuingStateRaw — the raw ICAO issuing state code as it appears in the MRZ, before conversion to a full country name.
  • nationalityRaw — the raw ICAO nationality code as it appears in the MRZ, before conversion to a full country name.
• New UI button visibility controls: Added three new MRZScannerConfig properties to control the visibility of toggle buttons in the scanning UI:
  • isBeepButtonVisible — shows or hides the beep sound toggle button (default: true).
  • isVibrateButtonVisible — shows or hides the vibration toggle button (default: true).
  • isFormatSelectorVisible — shows or hides the document format selector at the bottom of the scanning UI (default: true).
