When executing Firebase Functions from a Flutter app, the process stops

Question

I executed Firebase Functions in the following way

      result = await FirebaseFunctions.instance.httpsCallable(triggerName).call<void>();

When I run this process, the following error code is displayed, and the process stops

Error getting App Check token. Error: com.google.firebase.FirebaseException: No AppCheckProvider installed.

However, I haven't implemented App Check. How can I resolve this error code and proceed with the subsequent processing?

Also, when checking the logs on the functions side, there are no errors or outputs.

By the way, during debugging, when confirming the operation with breakpoints, the process stops right after executing FirebaseFunctions. However, when I step through, the process continues without any issues...

Make sure you're initializing your firebase-project

import 'package:firebase_app_check/firebase_app_check.dart';
import 'package:firebase_core/firebase_core.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(); // Make sure you call this
  FirebaseAppCheck.instance // Only needed if you use App checks
      .installAppCheckProviderFactory(
          AppCheckProviderFactory(
              provider: SafetyNetAppCheckProviderFactory())
      );
  runApp(MyApp());

}
