如何将一个文件中的有状态小部件中创建的列表访问到另一个文件中的无状态小部件？

// 有状态小部件文件
import 'package:flutter/material.dart';

class StatefulWidgetWithList extends StatefulWidget {
  @override
  _StatefulWidgetWithListState createState() => _StatefulWidgetWithListState();
}

class _StatefulWidgetWithListState extends State<StatefulWidgetWithList> {
  List<String> dataList = ['Item 1', 'Item 2', 'Item 3'];

  @override
  Widget build(BuildContext context) {
    return Container(
      child: StatelessWidgetWithoutList(dataList: dataList),
    );
  }
}

// 无状态小部件文件
import 'package:flutter/material.dart';

class StatelessWidgetWithoutList extends StatelessWidget {
  final List<String> dataList;

  StatelessWidgetWithoutList({required this.dataList});

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      itemCount: dataList.length,
      itemBuilder: (context, index) {
        return ListTile(
          title: Text(dataList[index]),
        );
      },
    );
  }
}
