Error: Couldn't resolve the package 'path_provider' in 'package:path_provider/path_provider.dart' if (dart.library.io) import using

Question

I know that the path_provider is not meant for the web. And I'm trying to separate implementations for web and mobile platforms through imports of the respective files, however, I get an error ONLY when compiling.

Please help me.

Error:

How I use it

import 'package:locale_cache/database/database_helper.dart' if (dart.library.html) 'database_helper_web.dart' if (dart.library.io) 'database_helper_mobile.dart';

final DatabaseHelper _databaseHelper = DatabaseHelper();

P.s. I have tried flutter clean and pub get
