    final oldDbPath = join((await getDatabasesPath())!, '$databaseName.db');

Just remove ! operand from fileflutter_cache_manager-3.0.0-nullsafety.1/lib/src/storage/cache_info_repositories/cache_object_provider.dart in line 208:29 till official update come, it occurs after you upgrade sqflite to 2.0.0+3
