How to Use Cached Images in Flutter

To use the cached_network_image package, you need to add cached_network_image package in your flutter project. Open your terminal and go to your project directory and execute the following command:

flutter pub add cached_network_image

Import the Package

Now, you need to import the cached_network_image package in your flutter application. To import the cached_network_image package, open your main.dart file and add the following import statement:

import 'package:cached_network_image/cached_network_image.dart';

Use the Package

Now, you can use the cached_network_image package in your flutter application. To use the cached_network_image package, open your main.dart file and add the following code in it:

import 'package:flutter/material.dart';
import 'package:cached_network_image/cached_network_image.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Use Cached Images in Flutter',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Use Cached Images in Flutter'),
        ),
        body: Center(
          child: CachedNetworkImage(
            imageUrl: 'https://picsum.photos/250?image=9',
            placeholder: (context, url) => CircularProgressIndicator(),
            errorWidget: (context, url, error) => Icon(Icons.error),
          ),
        ),
      ),
    );
  }
}

In this code:

• imageUrl is the URL of the image you want to cache.
• placeholder is a widget displayed while the image is loading.
• errorWidget is displayed in case of any loading error.
