i am new to dart I would like to find out how to write a code in dart for An instance of a class that is initialized with data from a file

void main() async {
  final file = File('OOPmovie_metadata.csv');
  Stream<String> lines =
      file.openRead().transform(utf8.decoder).transform(LineSplitter());

  try {
    await for (var line in lines) {
      print('$line : ${line.length} characters');
    }
    print('file is closed');
  } catch (e) {
    print('error : $e');
  }
}

this what i tried and i keep getting this error : PathNotFoundException: Cannot open file, path = ‘OOPmovie_metadata.csv’ (OS Error: The system cannot find the file specified.

, errno = 2)“
