please, can you change to null safety? it's very quick in your project

thanks

Try to merge the example app in mine, but there is this error:
nfc_plugin/Utils.kt: (100, 23): Only safe (?.) or non-null asserted (!!.) calls are allowed on a nullable receiver of type Tag?
The example app instead works perfectly. Might you know how to solve the bug?

Thanks

Hi!

If I open my Android app, and send it to the background, the onNfcMessage event doesn't fire when scanning an NFC tag. The app opens as expected, but the event deosn't fire.

Everything works fine if the app is not running when scanning the tag, as it checks the "nfcStartedWith".
If I scan the tag while the app is open, everything also works just fine.

Any suggestions of what could be wrong?

Hi, i' m trying to read an nfc card wich has not any message and the error i get is:

D/FlutterNfcPlugin( 6804): callback: onTagDiscovered {error=Cannot parse NDEF message: java.lang.IllegalStateException: ndef must not be null, message=null}

In other android applications in play store, i can get the tag id (serial number) although the tag has no messages (null).

How can i implement this?

Thanks!

Started getting this warning after updating to Flutter 2.5

The plugin `flutter_nfc_plugin` uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

Apple has launched iOS 16.1 which allows deleting wallet meaning they allow other developers to access the API
