Flutter，如何让Listview.builder锚定在底部

import 'package:flutter/material.dart';

class MyListView extends StatefulWidget {
  @override
  _MyListViewState createState() => _MyListViewState();
}

class _MyListViewState extends State<MyListView> {
  ScrollController _scrollController = ScrollController();

  @override
  void initState() {
    super.initState();
    WidgetsBinding.instance.addPostFrameCallback((_) {
      _scrollController.jumpTo(_scrollController.position.maxScrollExtent);
    });
  }

  @override
  Widget build(BuildContext context) {
    return ListView.builder(
      reverse: true,
      controller: _scrollController,
      itemCount: 10, // 假设有10个列表项
      itemBuilder: (BuildContext context, int index) {
        return ListTile(
          title: Text('Item ${index + 1}'),
        );
      },
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: Scaffold(
      appBar: AppBar(
        title: Text('ListView.builder Demo'),
      ),
      body: MyListView(),
    ),
  ));
}
