I have a ListView in AlertDialog container. There is an InkWell method but ripple effect doesn't work and I can't put the separator. How can I put separator and have ripple effect?

Widget setupAlertDialoadContainer(context) {
return Container(
  color: Colors.white,
  height: 300.0,
  width: 300.0,
  child: ListView.builder(
      itemCount: showroomModel.length,
      itemBuilder: (BuildContext context, int index) {
        return InkWell(
          onTap: () => {
            print(showroomModel[index]),
          },
          child: ListTile(
            title: Text(showroomModel[index]),
          ),
        );
      }),
);

}

For Separator & Ripple Effect Use

    ListView.separated(
         itemCount: 25,
         separatorBuilder: (BuildContext context, int index) => Divider(height: 1),
         itemBuilder: (BuildContext context, int index) {
           return  Inkwell(child: 
ListTile(
             title: Text('item $index'),
           ));
         },
    );

For the InkWell ripple effect, try wrapping the InkWell in a Material widget.

Material(
  child: InkWell(
    onTap: () {
      print(showroomModel[index]);
    },
    child: ListTile(
      title: Text(showroomModel[index]),
    ),
  ),
)

For the separator use ListView.separated as in Tasnuva oshin's answer.

Check this out :

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: HomePage(),
    );
  }
}

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

  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
