Flutter – Problem with using go_router and Listview.builder together

I am trying to build a dictionary app. My homepage, which is returned from the main file, is supposed to have the words. I want to implement go router in the home screen which is called DictionaryScreenEnglish, and by tapping the words I want go router to push to the entry pages. I am unable to implement the onTap functionality when the words are tapped. Below is the code of my DictionaryScreenEnglish

import 'package:flutter/material.dart';
import 'package:go_router/go_router.dart';
import 'package:zeetionary/dictionary/english_dictionary/alphabet/letter_a/letters_ab/en_entry_aback.dart'; // a page that contains the entry for the word "aback"

final GoRouter _router = GoRouter(
  routes: <RouteBase>[
    GoRoute(
      path: '/dictionaryenglish',
      builder: (BuildContext context, GoRouterState state) {
        return const DictionaryScreenEnglish();
      },
      routes: <RouteBase>[
        GoRoute(
          path: 'english/:aback',
          builder: (BuildContext context, GoRouterState state) {
            return EnglishEntryAback();
          },
        ),
      ],
    ),
  ],
);

class DictionaryScreenEnglish extends StatefulWidget {
  const DictionaryScreenEnglish({Key? key}) : super(key: key);

  @override
  State<DictionaryScreenEnglish> createState() =>
      _DictionaryScreenEnglishState();
}

class _DictionaryScreenEnglishState extends State<DictionaryScreenEnglish> {
  final GlobalKey<ScaffoldState> scaffoldKey = GlobalKey<ScaffoldState>();
  final List<String> allWordsEnglish = [
    "aback",
    "abacus",
  ];
  List<String> filteredWords = [];
  final TextEditingController _searchController = TextEditingController();

  @override
  void initState() {
    super.initState();
    filteredWords = List.from(allWordsEnglish);
  }

  void filterWords(String query) {
    setState(() {
      filteredWords = allWordsEnglish
          .where((word) => word.toLowerCase().contains(query.toLowerCase()))
          .toList();
    });
  }

  void clearSearch() {
    _searchController.clear();
    filterWords('');
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      key: scaffoldKey,
      body: Column(
        mainAxisAlignment: MainAxisAlignment.center,

                  onChanged: filterWords,
                  decoration: InputDecoration(
                    labelText: 'Search here',
                    prefixIcon: const Icon(Icons.search),
