嗨，我有一个页面，你可以在列表视图中创建一个项目，并给它一个名称，现在我想当你点击该项目，它去自己的专用页面上的应用程序栏上的名称.

下面是列表视图代码：

import 'package:flutter/material.dart';
import 'package:flutter_speed_dial/flutter_speed_dial.dart';
import 'package:attendance/insideList.dart';

class lists extends StatefulWidget {
  const lists({super.key});

  @override
  State<lists> createState() => _listsState();
}

class _listsState extends State<lists> {
  List<String> _items = [];
  late TextEditingController _textController;
  @override
  void initState() {
    super.initState();
    _textController = TextEditingController();
  }

  @override
  void dispose() {
    _textController.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    _items.sort();
    return Scaffold(
      body: _items.length > 0
          ? ListView.separated(
              itemCount: _items.length,
              itemBuilder: (_, index) {
                return ListTile(
                  leading: const Icon(Icons.school),
                  trailing: const Icon(Icons.arrow_forward),
                  title: Center(child: Text('${_items[index]}')),
                  **//here the attempt I made that didnt work**
                  onTap: () {
                    Navigator.push(
                        context,
                        MaterialPageRoute(
                            builder: ((context) => InsideList(index))));
                  },
                  onLongPress: (() async {
                    await showDialog(
                        context: context,
                        builder: ((context) {
                          return AlertDialog(

                              "Are you sure you want to delete this class?",
                              style: TextStyle(fontSize: 15),
                            ),
                            actions: [
                              TextButton(

• • 这是我为新页面创建的新dart文件：**

import 'package:flutter/material.dart';

class InsideList extends StatelessWidget {
  final int index;

  InsideList(this.index);

  List<String> _students = [];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: const Text("attendance"),
          centerTitle: true,
          backgroundColor: const Color.fromARGB(255, 22, 37, 50),
          toolbarHeight: 65,
          shape: const RoundedRectangleBorder(
            borderRadius: BorderRadius.vertical(
              bottom: Radius.circular(30),
            ),
          ),
        ),
        body: _students.length > 0
            ? Center(child: Text("hi"))
            : Center(
                child:
                    Text("You currently have no students. Add from below.")));
  }
}
