facing the same issue with Flutter 3

[beratpolat]

It's error from null safety of kotlin

please try below in FlutterMrzScannerPlugin.kt

class MRZScannerFactory(private val messenger: BinaryMessenger) : PlatformViewFactory(StandardMessageCodec.INSTANCE) {

override fun create(context: Context?, id: Int, o: Any?): PlatformView {
    return MRZScannerView(context!!, messenger, id)
}

}

Attention Context? context!!

From detail, you can see PlatformViewFactory source code:

public abstract PlatformView create(@Nullable Context context, int viewId, @Nullable Object args);
