我试图在Flutter中将列表插入到sql数据库中，但是我不知道该怎么办，有人可以帮助我吗？

当我初始化mi数据库时，我有这个：

Directory documentsDirectory = await getApplicationDocumentsDirectory();
    String path = join(documentsDirectory.path, "tuCuestionarioDB.db");
    return await openDatabase(path, version: 1, onOpen: (db) {},
        onCreate: (Database db, int version) async {
      await db.execute("CREATE TABLE Question ("
          "id INTEGER PRIMARY KEY,"
          "subject INTEGER,"
          "topic INTEGER,"
          "question TEXT,"
          "answer INTEGER,"
          "answers TEXT ARRAY," //THIS IS MY LIST<STRING>
          "rightAnswer INTEGER,"
          "correctly BIT,"
          "answered BIT"
          ")");
    });

我有这个要插入数据：

 newQuestion(Question newQuestion) async {
     final db = await database;
    //get the biggest id in the table
    var table = await db.rawQuery("SELECT MAX(id)+1 as id FROM Question");
    int id = table.first["id"];
    //insert to the table using the new id
    var raw = await db.rawInsert(
        "INSERT Into Question (id,subject,topic,question,answer,answers,rightAnswer,correctly,answered)"
        " VALUES (?,?,?,?,?,?,?,?,?)",
        [id != null ? id : 0, newQuestion.subject, newQuestion.topic,newQuestion.question,newQuestion.answer,newQuestion.answers,newQuestion.rightAnswer,newQuestion.correctly ? 1 : 0,newQuestion.answered ? 1 : 0]);
    return raw;
  }

但是当y尝试插入这样的值时：

{subject: 1, topic: 1, question: What is the best community?, answer: 3, rightAnswer: 0, answers: [Stack Overflow, Facebook, Yahoo Answers], correctly: false, answered: false}

我收到这样的错误：

发生异常。

SqfliteDatabaseException（DatabaseException（java.lang.String无法转换为java.lang.Integer）sql’INSERT

Question（id，subject，topic，question，answer，answers，rightAnswer，正确，已回答）值（？，？，？
，？，？，？，？，？，？，？）’args [0，1，1，什么是最好的社区？，3，[Stack Overflow，Facebook，Answers

当我删除anwsers字段时，我没有任何错误
