init of Mapkit is mot working

[lowfreq2010]

Hello,

I get the following problem when try to start android app with map_kit_lite

E/flutter (26831): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Invalid argument(s): Failed to lookup symbol 'yandex_maps_flutter_is_init': undefined symbol: yandex_maps_flutter_is_init
E/flutter (26831): #0 DynamicLibrary.lookup (dart:ffi-patch/ffi_dynamic_library_patch.dart:33:70)

E/flutter (26831): #7 _RawReceivePort._handleMessage (dart:isolate-patch/isolate_patch.dart:184:12)
E/flutter (26831):

our code is :

import 'package:yandex_maps_mapkit_lite/init.dart' as init;

void main() async {
WidgetsBinding widgetsBinding = WidgetsFlutterBinding.ensureInitialized();
FlutterNativeSplash.preserve(widgetsBinding: widgetsBinding);
await init.initMapkit(
apiKey: 'XXX-XXXX-xXXXXXX'
);
}

package has been installed as described on pub.dev page for mapkit_lite

ios app starts just fine. How can we fix this strange problem? Thanks in advance
