v7.2.0

Highlights

• Added support for switching between lens types (normal, wide, zoom) using the switchCamera() method with ToggleLensType or SelectCamera options.
• Added rawDecodedBytes field to Barcode which replaces Barcode.rawBytes. On Apple platforms, this returns a DecodedVisionBarcodeBytes containing bytes (decoded payload, without header/padding) and rawBytes (full raw payload, available on iOS 17.0+ / macOS 14.0+). On Android and web, this returns a DecodedBarcodeBytes containing bytes.

Improvements

• [Android] Migrated barcode bounding box from boundingBox to cornerPoints for more accurate scan window detection.
• Added support for ITF-Two-of-Five.
• Added constants for testing the method channel methods in MobileScannerMethods and MobileScannerEvents.
• The global method calculateBoxFitRatio() is now deprecated.

Bug Fixes

• [Android] Fixed incorrect texture size on orientation change.
• [Android] Fixed a bug where the isPaused flag was not reset when start() was called.
• [Android] Fixed imageAnalysis not being unbound on dispose.
• [Android] Fixed an issue where the app orientation handling was not respecting auto-rotate settings
• [Apple] Fixed rawBytes returning incorrect data for barcodes containing non-ASCII characters (e.g. ø). For QR codes, bytes are now extracted directly from the error-corrected bit stream via CIQRCodeDescriptor, bypassing the Vision string API entirely. For Aztec, DataMatrix, PDF417 and linear formats, the ISO-Latin-1 round-trip is used to recover the original bytes from payloadStringValue.
• [Apple] Fixed displayValue returning a garbled Latin-1 string (e.g. hellø) for barcodes with non-ASCII UTF-8 content. It is now correctly decoded to UTF-8 (e.g. hellø).
• [Apple] Fixed a bug where the barcode type results did not have a value.
• [Apple] Fixed camera rotating, even when rotation is locked.
• [macOS] Fixed barcode overlay text displaying upside down.
• Fixed barcode overlay rendering at wrong position after orientation change.
• Fixed a bug where taps were ignored on the scanner widget.
• Fixed a bug where a controller that was only disposed would throw an incorrect error code.

v7.1.3

• Overlay: Updated BarcodePainter to receive deviceOrientation and dynamically adjust cameraPreviewSize, fixing barcode overlay misalignment during device rotation changes .

• [Android] Refactored orientation detection to use OrientationEventListener instead of BroadcastReceiver for ACTION_CONFIGURATION_CHANGED, ensuring physical device orientation is captured correctly and preventing unwanted screen rotations on MobileScanner initialization .

• [Android] Changed minSDK from 21 to 23 in line with Flutter requirements.

• [Android] Removed deprecated renderscript api's, improved performance for analysis.

• [Apple] Prevent half-stopped camera state causing false ALREADY_STARTED.

• [Apple] Fixed a bug where invalid images would cause crashes when processing them with CoreVideo.

v7.1.2

• Fixed an issue with the initialZoom parameter.

v7.1.1

• Fixed missing import of 'package:meta/meta.dart' on older Flutter sdk's

v7.1.0

Highlights

• [Apple & Android] Added tap to focus functionality. You can enable it in the MobileScanner widget.
• [Apple & Android] You can now set the initial zoom factor using the initialZoom parameter in the startOptions.

Bug Fixes and Improvements

• [iOS] Increased minimum os level to 13 due to Flutter requirements.
• [macOS] Increased minimum os level to 10.15 due to Flutter requirements.
• [Android] Update to Java 17, and update other dependencies.
• [Apple] Improved fallback for when camera is not found.
• Added a Barcode.scaleCorners() method.

v6.0.11

• [Android] Update camerax dependencies to support 16KB pages sizes.

v7.0.1

• Added error handling for when MobileScannerController.start is called without an active MobileScanner widget.

v7.0.0

This version finalizes all changes from the beta and release candidate cycles and introduces major improvements, bug fixes, and breaking changes.

BREAKING CHANGES:

• Requires Flutter 3.29.0 or higher.
• The initial camera facing direction in MobileScannerState is now CameraFacing.unknown.
• Removed the deprecated EncryptionType.none. Use EncryptionType.unknown instead.
• The errorBuilder and placeholderBuilder no longer have a Widget argument.
• Removed the MobileScannerErrorBuilder typedef.

Highlights

• [iOS/macOS] Migrated to the Vision API with a unified Apple codebase.
• [Android] Removed dependency on kotlin-bom and updated CameraX and camera-camera2 dependencies.
• Support for pause/resume functionality across platforms.
• MobileScannerErrorCode now includes readable error messages in debug mode.
• Hot-restart during development now works correctly.
• Added overlay widgets for barcode and scan window visualization.
• Exposed new API parameters like autoZoom, invertImage, and lifecycle handling.

Bug Fixes and Improvements

• [Apple]
  • Fixed rotation, orientation, and zoom behavior.
  • Resolved incorrect barcode overlay dimensions and corner coordinates.
  • Fixed a crash when stopping the camera with a nil device.
  • Fixed build issues including optional chaining on non-optional values.
• [Android]
  • Fixed rotation and orientation issues.
  • Resolved timing issues in SurfaceProducer with Kotlin 1.8+.
  • Fixed resource leaks and improved image analysis compatibility.
  • Improved logging behavior (CameraX logs only errors).
• [macOS]
  • Fixed mirrored images and build issues.
• [Web]
  • Fixed barcode overlay not displaying due to incorrect corner point data.

v7.0.0-rc.2

Bugs fixed:

• [Apple] Fixed build issues "Cannot use optional chaining on non-optional value".

v7.0.0-rc.1

After six months of development, Version 7.0.0 is finally moving out of beta with this release candidate!
A stable release is scheduled for next week.

Improvements:

• [Android] Remove the dependency on org.jetbrains.kotlin:kotlin-bom.
• [Android] Updated camerax dependencies.
• Hot-restart for development purposes is now working correctly
• Added message to MobileScannerErrorCode, which will be shown if kDebugMode is true. Otherwise, a generic error message will appear.
• Fixed issues regarding initialization of the MobileScannerController, which could result in a black screen without error message.

Bugs fixed:

• [Android] Fixed rotation & orientation issues.
• [Apple] Fixed rotation & orientation issues.
• [Apple] Fixed a crash when stopping the camera when the camera device is nil.
• [macOS] Fixed image not being mirrored.
• [Web] Fixed barcode corners not being passed correctly resulting in no overlay being drawn.
