将数据从选项卡栏视图传递到flutter中的屏幕

// 定义数据模型
class DataModel {
  final String title;
  final String description;

  DataModel(this.title, this.description);
}

// 创建选项卡栏视图
class TabBarViewScreen extends StatelessWidget {

              Tab(text: 'Screen 1'),
              Tab(text: 'Screen 2'),
            ],
          ),
        ),
        body: TabBarView(
          children: [
            Screen1(),
            Screen2(),
          ],

// 创建屏幕1

        onPressed: () {
          // 导航到屏幕2，并传递数据
          Navigator.pushNamed(
