mobile_scanner

Bugs fixed:

• [iOS] Fixed a bug that caused a crash when switching from camera.

Improvements:

• [iOS] No longer automatically focus on faces.
• [iOS] Fixed build error.
• [Web] Waiting for js libs to load.
• Do not returnImage if not specified.
• Added raw data in barcode object.
• Fixed several bugs.

This big release contains all improvements from the beta releases. In addition to that, this release contains:

Improvements:

• Fixed an issue in which the scanner would freeze if two scanner widgets where placed in a page view, and the paged was swiped. An example has been added in the example app. You need to set startDelay: true if used in a page view.
• [Web] Automatically inject js libraries.
• [macOS] The minimum build version is now macOS 10.14 in according to the latest Flutter version.
• [Android] Fixed an issue in which the scanWindow would remain even after disposing the scanner.
• Updated dependencies.

Fixes:

• Fixes a permission bug on Android where denying the permission would cause an infinite loop of permission requests.
• Updates the example app to handle permission errors with the new builder parameter. Now it no longer throws uncaught exceptions when the permission is denied.
• Updated several dependencies

Features:

• Added a new errorBuilder to the MobileScanner widget that can be used to customize the error state of the preview. (Thanks @navaronbracke !)

Deprecated:

• The onStart method has been renamed to onScannerStarted.
• The onPermissionSet argument of the MobileScannerController is now deprecated.

BREAKING CHANGES:

• MobileScannerException now uses an errorCode instead of a message.
• MobileScannerException now contains additional details from the original error.
• Refactored MobileScannerController.start() to throw MobileScannerExceptions with consistent error codes, rather than string messages. To handle permission errors, consider catching the result of MobileScannerController.start().
• The autoResume attribute has been removed from the MobileScanner widget. The controller already automatically resumes, so it had no effect.
• Removed MobileScannerCallback and MobileScannerArgumentsCallback typedef.
• [Web] Replaced jsqr library with zxing-js for full barcode support.

Improvements:

• Toggling the device torch now does nothing if the device has no torch, rather than throwing an error.
• Removed called stop while already stopped messages.

Features:

• You can now provide a scanWindow to the MobileScanner() widget.
• You can now draw an overlay over the scanned barcode. See the barcode scanner window in the example app for more information.
• Added a new placeholderBuilder function to the MobileScanner widget to customize the preview placeholder.
• Added autoStart parameter to MobileScannerController(). If set to false, controller won't start automatically.
• Added hasTorch function on MobileScannerController(). After starting the controller, you can check if the device has a torch.
• [iOS] Support torchEnabled parameter from MobileScannerController() on iOS
• [Web] Added ability to use custom barcode scanning js libraries by extending WebBarcodeReaderBase class and changing barCodeReader property in MobileScannerWebPlugin

Fixes:

• Fixes the missing gradle setup for the Android project, which prevented gradle sync from working.
• Fixes MobileScannerController.stop() throwing when already stopped.
• Fixes MobileScannerController.toggleTorch() throwing if the device has no torch. Now it does nothing if the torch is not available.
• Fixes a memory leak where the MobileScanner would keep listening to the barcode events.
• Fixes the MobileScanner preview depending on all attributes of MediaQueryData. Now it only depends on its layout constraints.
• Fixed a potential crash when the scanner is restarted due to the app being resumed.
• [iOS] Fix crash when changing torch state

BREAKING CHANGES:

• The arguments parameter of onDetect is removed. The data is now returned by the onStart callback in the MobileScanner widget.
• onDetect now returns the object BarcodeCapture, which contains a List of barcodes and, if enabled, an image.
• allowDuplicates is removed and replaced by MobileScannerSpeed enum.
• onPermissionSet in MobileScanner widget is deprecated and will be removed. Use the onPermissionSet onPermissionSet callback in MobileScannerController instead.
• [iOS] The minimum deployment target is now 11.0 or higher.

Features:

• The returnImage is working for both iOS and Android. You can enable it in the MobileScannerController. The image will be returned in the BarcodeCapture object provided by onDetect.
• You can now control the DetectionSpeed, as well as the timeout of the DetectionSpeed. For more info see the DetectionSpeed documentation. This replaces the allowDuplicates function.

Other improvements:

• Both the [iOS] and [Android] codebases have been refactored completely.
• [iOS] Updated POD dependencies

BREAKING CHANGES:

• [Android] SDK updated to SDK 33.

Features:

• [Web] Add binaryData for raw value.
• [iOS] Captures the last scanned barcode with Barcode.image.
• [iOS] Add support for multiple formats on iOS with BarcodeScannerOptions.
• Add displayValue which returns barcode value in a user-friendly format.
• Add autoResume option to MobileScannerController which automatically resumes the camera when the application is resumed

Other changes:

• [Android] Revert camera2 dependency to stable release

• Several minor code improvements

BREAKING CHANGES:

This version is the last version that will run on Flutter 2.x

Bugfixes:

This version uses the MLKit play-services model on Android in order to save space. With the example app, this version reduces the release version from 14.9MB to 7MB. More information: https://developers.google.com/ml-kit/vision/barcode-scanning/android

Bugfixes:

• Add null checks for Android.
• Update camera dependency for Android.
• Fix return type for analyzeImage.

Bugfixes:

• Fix for 'stream already listened to' exception.
• Fix building on Android with latest Flutter version.

BREAKING CHANGES:

This version adds a new allowDuplicates option which now defaults to FALSE. this means that it will only call onDetect once after a scan. If you still want duplicates, you can set allowDuplicates to true. This also means that you don't have to check for duplicates yourself anymore.

New features:

Bugfixes:

• Fixed hot reload not working.

• Fixed iOS MLKit version not resolving the latest version.

You can provide a path to controller.analyzeImage(path) in order to scan a local photo from the gallery! Check out the example app to see how you can use the image_picker plugin to retrieve a photo from the gallery. Please keep in mind that this feature is only supported on Android and iOS.

Another feature that has been added is a format selector! Just keep in mind that iOS for now only supports 1 selected barcode.
