How to check for internet connection before trying to init Supabase?

I'm looking to add an 'Internet connection checker' to my Flutter app (i.e. web & Android), but there would seem to be a contradiction between where the typical internet connection checker widget is inserted (i.e. the home page) and the fact that my 'main' class includes a number of setup calls made before the 'runApp' step that depend on internet connection, e.g. initialising Supabase.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  final aPrefs = await SharedPreferences.getInstance();
  await SupabaseUtil.init();
  await GdSubscriptionService.init();

  runApp(
      ProviderScope(
        overrides: [
          sharedPrefsProvider.overrideWithValue(aPrefs),
        ],
        child: const MyApp(),));
}

Wouldn't it make more sense to set the internet connection checking at the start of the main class code?

Any suggestions?

You can create class with a function to check connectivity, something like this

import 'package:connectivity_plus/connectivity_plus.dart';
import 'package:voters_app/widgets/shared/toast_service.dart';

class NetworkUtils {
  static Future<bool> checkInternetConnection() async {
    final connectivityResult = await Connectivity().checkConnectivity();
    if (connectivityResult.contains(ConnectivityResult.none)) {
      // print or show toast to inform user that there is no internet connection.
      return false;
    }
    return true;
  }
}

I am using this flutter package Connectivity_plus You can check at the main.dart the connection and do whatever you want by the return. also I recommend you to use state manager to handle this.
