Introduction:

Envision you have a list of things on your phone or PC screen. Presently, I envision that everything on the list has an alternate color. For instance, the main thing may be white, the subsequent thing may be dark, the third thing may be white once more, etc. This is known as a zebra-striped list view. It is called that since it seems to be the stripes of a zebra. This is expected to make the list more alluring and straightforward. It can assist you with finding what you are searching for quicker and better.

How to implement code in dart file :

You need to implement it in your code respectively:

Create a new dart file called main.dart inside the lib folder.

To make a striped ListView (with the ListView.builder() constructor) in Flutter, you can utilize the itemBuilder parameter to return an alternate widget for everything in light of its index. In by far most cases, you can utilize a ternary operator to shift back and alternate between 2 colors for the background of everything as displayed beneath:

ListView.builder(
  itemCount: 132,
  itemBuilder: (context, index) {
    return Container(
      // alternate colors
      color: index % 2 == 0 ? Colors.red : Colors.green, 
      /*...*/
    );
  },
);

First, we will generate dummy data for the list

final List<String> items = List.generate(100, (index) => 'Item $index');

Then, we will add the ListView.builder() method to the body part. In this method, we will add itemCount was items. length. Also, we will add the itemBuilder function. In this, we will add the final color is equal to the index.isEven then shows a white color else cyan color.

ListView.builder(
  itemCount: items.length,
  itemBuilder: (context, index) {
    final color = index.isEven ? Colors.white : Colors.cyan[100];
    return Container(
      color: color,
      padding: const EdgeInsets.symmetric(vertical: 18, horizontal: 24),
      child: Text(
        items[index],
        style: const TextStyle(fontSize: 18),
      ),
    );
  },
),

Then, we will return a container with white color, padding, and items[index].

When we run the application, we ought to get the screen’s output like the underneath screen capture.

Code File:

import 'package:flutter/material.dart';
import 'package:flutter_zebra_list_view_demo/splash_screen.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      // hide the debug banner
      debugShowCheckedModeBanner: false,
      title: 'KindaCode.com',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const Splash(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  MyHomePage({super.key});

  final List<String> items = List.generate(100, (index) => 'Item $index');

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        automaticallyImplyLeading: false,
        centerTitle: true,
        title: const Text('Flutter Zebra Striped ListView Demo'),
        backgroundColor: Colors.cyan,
      ),
      body: ListView.builder(
        itemCount: items.length,
        itemBuilder: (context, index) {
          final color = index.isEven ? Colors.white : Colors.cyan[100];
          return Container(

        },
      ),
    );
