Flutter :如何将动态列表插入到sqflite

import 'package:sqflite/sqflite.dart';
import 'package:path/path.dart';

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

  static Database? _db;

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

  DatabaseHelper.internal();

  Future<Database> initDb() async {
    String databasesPath = await getDatabasesPath();
    String path = join(databasesPath, 'my_database.db');
    return await openDatabase(path, version: 1, onCreate: _onCreate);
  }

  void _onCreate(Database db, int version) async {
    await db.execute(
        'CREATE TABLE IF NOT EXISTS my_table (id INTEGER PRIMARY KEY, name TEXT)');
  }

  Future<int> insertData(String name) async {
    Database? database = await db;
    return await database!.insert('my_table', {'name': name});
  }
}

void main() async {
  DatabaseHelper dbHelper = DatabaseHelper();
  await dbHelper.insertData('Item 1');
  await dbHelper.insertData('Item 2');
  await dbHelper.insertData('Item 3');
}
