Steps to Reproduce
All I did was copying the code from here.
I tried both given versions of the code but the problem persists.
main.dart:
import 'misc/appInfo.dart' as appInfo;
Future<void> main() async {
await appInfo.init();
runApp(MyApp());
}
appInfo:
import 'package:package_info_plus/package_info_plus.dart';
late String appName;
late String packageName;
late String version;
late String buildNumber;
Future<void> init() async {
PackageInfo packageInfo = await PackageInfo.fromPlatform();
appName = packageInfo.appName;
packageName = packageInfo.packageName;
version = packageInfo.version;
buildNumber = packageInfo.buildNumber;
}
