veriff_flutter #
Flutter plugin for Veriff.
Requirements #
Integration with Veriff Flutter Plugin requires the project to target at least iOS version 13.0 and Android version 8.0 (api 26) or higher.
Add plugin to a project #
Add the Veriff Flutter Plugin to your pubspec.yaml file:
dependencies:
veriff_flutter
copied to clipboard
iOS specific configuration #
Add usage descriptions to application Info.plist

Not adding these usage descriptions causes system to kill application when it requests the permissions when needed.

Veriff requires camera, microphone, photo library and optionally NFC reader permissions for capturing photos, video and scanning passport during identification. Your application is responsible to describe the reason why camera, microphone, photo library and NFC reader is used. You must add 3 descriptions listed below to Info.plist of your application with the explanation of the usage.

NSCameraUsageDescription
NSMicrophoneUsageDescription
NSPhotoLibraryUsageDescription

Add required steps for NFC scanning

Add NFCReaderUsageDescription description to Info.plist.

The application needs to define the list of application IDs or AIDs it can connect to, in the Info.plist file. The AID is a way of uniquely identifying an application on a ISO 7816 tag, which is usually defined by a standard.
<key>com.apple.developer.nfc.readersession.iso7816.select-identifiers</key>
<array>
<string>A0000002471001</string>
<string>A0000002472001</string>
<string>00000000000000</string>
</array>
copied to clipboard

Add a new entitlement for NFC scanning. This new entitlement is added automatically by Xcode when enabling the Near Field Communication Tag Reading capability in the target Signing & Capabilities. After enabling the capability the *.entitlements file needs to contain the TAG format:
<key>com.apple.developer.nfc.readersession.formats</key>
<array>
<string>TAG</string>
</array>
