Когда я запускаю этот код в Dart Editor, я получаю сообщение об ошибке:

Почему я получаю эту проблему? Спасибо.

Я использую CentOS 7 и Dart 1.10.0.

Это известная проблема, вызванная нарушением изменения Дартс 1.10.
- https://github.com/bwu-dart/bwu_datagrid/pull/108
- https://github.com/bwu-dart/bwu_datagrid/issues/106
Я стараюсь, чтобы получить обновленную версию, опубликованную как можно скорее.
