Null safety

Hello,
Do you have any plans to migrate to null safety?

null object error in onActivityResult

Seeing errors like:

com.microblink.flutter.MicroblinkFlutterPlugin.onActivityResult
MicroblinkFlutterPlugin.java, line 171
java.lang.NullPointerException: Attempt to invoke interface method 'void io.flutter.plugin.common.MethodChannel$Result.success(java.lang.Object)' on a null object reference

Stack trace at the bottom. It looks like you might be addressing this in the next release. Is there a timeline on getting that out?

We are mostly seeing this with live users, still working on recreating it.

App Center provides two stack traces:

Unable to use IdRecognizer with USDL

I am trying to update to 6.x but so far unable to. The USDL recognizer doesn't seem to work anymore (filed separate issue for that), so I thought I could use the IdBarcodeRecognizer. I'm not able to get that to work, due to this error

flutter: type '_Map<String, dynamic>' is not a subtype of type 'BarcodeElements?'
flutter:
#0      new IdBarcodeRecognizerResult
id_barcode_recognizer.dart:172
#1      IdBarcodeRecognizer.createResultFromNative
id_barcode_recognizer.dart:226
#2      MicroblinkScanner.scanWithCamera
microblink_scanner.dart:42
<asynchronous suspension>

I think you need a BarcodeElements(nativeResult["extendedElements"]) in the IdBarcodeRecognizerResult constructor.

Is there any way to get a patch change like this fast-tracked? I'm currently blocked on this update. Thanks!

UsdlCombinedRecognizer fails on IOS

We are seeing the UsdlCombinedRecognizer fail on IOS. Stack trace below. The native result of documentDataMatch is a bool from IOS but Android supplies an int (and the flutter code expects an int). Not sure if this is something you want to fix upstream, but I can provide a PR to patch it in the flutter package.

Sample error:

This is using the USDLRecognizer. It does not occur using the MrtdRecognizer.

ImagePicker

How can the flutter library, to use imagePickerController, allowing end user to chose image from camera instead of overlay scan ?

Need this for an out of mobile service use case scenario, where end user would not be able to pass ID information to hosted persistence api.

dependency does not exist

Hi, I created a new project and I am trying to add the dependency on my pubspec.yaml file as stablished on README:

dependencies:
  ...
  blinkid_flutter:

However it throws the following exception:

"Because project_name depends on blinkid_flutter any which doesn't exist (could not find package blinkid_flutter at https://pub.dartlang.org), version solving failed."

When I looked it up in https://pub.dartlang.org it really does not exist.

Type of the document returns Types.None for passports

Library is able to scan the passports and parse the result, But the type of the document always returns Types.None for passport documents. For the driver's license, the type is returned correctly.

I'm reading the type from below field,
result.classInfo.type

I have scanned passports of the below countries, But none of them returns the type.

Spain
German
India
Australia
Ireland
New Zealand
USA
Canada
China

Thanks.

Web Support

Hey BlinkID team,

Is there currently any plans for adding web support for this library?

Thank you

Readme file is misleading!

Testing with Flutter Driver

Does the BlinkID development team have any experience / guidance to offer for users that want to build flutter_driver integration tests that go through BlinkID scans?

We're picturing something where we have a set of test ID photos (can BlinkID provide any?) that our flutter_driver tests can push into the android emulator via ADB commands (we already have success calling adb from our integration tests to extend flutter_driver capabilities) so that our flutter_driver tests can go through workflows as true-to-use as possible, providing a photo to the emulator and getting back a normal scan result when it comes to ID scan steps

Disable instructions pane

I'm looking for the ability to do the equivalent of what is shown here: https://github.com/BlinkID/blinkid-ios/blob/dc1fa0df5ddd2bac21f313cc0253243a2b58f429/Transition%20guide.md?plain=1#L75

Disable the new built-in instructions if desired. I'm not seeing this in the flutter plugin OverlaySettings. Is this possible?

Expired Licence key crashes the application

API to check if the license key is expired is missing.

Failed to build `Android app` after adding `blinkid_flutter` to dependencies!

Could not resolve compiler classpath. Check if Kotlin Gradle plugin repository is configured in project ':app'.

FAILURE: Build failed with an exception.

What went wrong:
Could not determine the dependencies of task ':app:compileProductionDebugKotlin'.

Could not resolve all dependencies for configuration ':app:kotlinCompilerClasspath'.
Using insecure protocols with repositories, without explicit opt-in, is unsupported. Switch Maven repository 'maven2(http://maven.microblink.com)' to redirect to a secure protocol (like HTTPS) or allow insecure protocols. See https://docs.gradle.org/7.4/dsl/org.gradle.api.artifacts.repositories.UrlArtifactRepository.html#org.gradle.api.artifacts.repositories.UrlArtifactRepository:allowInsecureProtocol for more details.

Try:

Run with --stacktrace option to get the stack trace.
Run with --info or --debug option to get more log output.
Run with --scan to get full insights.

Scan result source question

For ID verification, the SDK seems to extract and parse information from the front of the card rather than the PDF417 code in the back, is this per design (some security concern)? Also, is there a way to change the configuration so that the information extracted about the document comes from the PDF417 instead? This is in case pieces of information on the front of the card are miss-read do to poor lighting conditions, font, etc.

I/Process ( 7490): Sending signal. PID: 7490 SIG: 9
Lost connection to device.

I have cloned the repo, ran the ./initFlutterSample.sh - cd to sample - Added blinkid_flutter to pubspec.yaml - pub get - flutter run (--debug) on device. App opens up, I press scan and App crashes with ☝️ error message.

I have tried adding native library from blinkid-android and added it to the build.gradle as dependency (LibBlinkID.aar) but then I get DuplicateClass error message since I already have blinkid_flutter in pubspec.yaml I think.

So what am I excatly missing in your example?

Return `nationality` in 2-letter ISO code

Combined recognizer result should really be returning nationality as 2-letter ISO codes of the respected countries. The same way it is done in ClassInfo: String? isoAlpha2CountryCode;

Info.plist missing required key (IOS)

Missing required key in info.plist while uploading to App Store after upgrading to 5.10.0.

old branch deleted

Hey, congrats on the new release!

It looks like this repo has been totally scrubbed though of the previous branches. Our work in progress project was using it and now all our builds and CI are failing. Could you make the old branch available somewhere we could point our pubspec.yaml at until we're able to migrate over to the new branch?
