大家好，我正在做一个flutter项目，我试图在一个sqflite数据库中保存数据。因为我是新来的flutter，所以我不明白我做错了什么，或者我犯了什么错误。
我得到的错误是

I/flutter (28200): *** WARNING ***

下面是我的代码从firestore数据库获取数据并保存到本地数据库（sqflite）

Future<void> getRecipeData() async {
    recipes = await RecipeModel().getRecipeDataList();
    count = await RecipeModel().getRecipeCount();

    //Converting List into Map
    for (int i=0; i<count;i++) {
      recipeMap[recipes[i].recipeID] = {
        'recipeName': recipes[i].recipeName,
        'recipeCategory': recipes[i].recipeCategory,
      };
    }
    //Storing data into database
    DatabaseHelper().saveRecipe(recipeMap);
  }

这是我的数据库类

class DatabaseHelper {
  static final DatabaseHelper _instance = DatabaseHelper.internal();

  factory DatabaseHelper() => _instance;

  final String recipeTable = 'recipeTable';
  final String recipeId = 'recipeId';
  final String recipeName = 'recipeName';
  final String recipeCategory = 'recipe_category';
  final String columnSynced = 'synced';

  static Database? _db;

  Future<Database?> get db async {
    if (_db != null) {
      return _db;
    }
    _db = await initDb();
    return _db;
  }

  DatabaseHelper.internal();

  initDb() async {
    String databasesPath = await getDatabasesPath();
    String path = join(databasesPath, 'recipe.db');

    var db = await openDatabase(path, version: 1, onCreate: _onCreate);
    return db;
  }

  void _onCreate(Database db, int newVersion) async {
    await db.execute(
        'CREATE TABLE $recipeTable($recipeId INTEGER PRIMARY KEY, $recipeName TEXT, $recipeCategory TEXT, $columnSynced INTEGER)');
  }

  Future<int> saveRecipe(Map<String, dynamic> recipe) async {
    var dbClient = await db;
    int res = await dbClient!.insert(recipeTable, recipe);
    return res;
  }
}

请帮助我解决这个问题。所有的努力都将受到赞赏。谢谢
