How to Add Images in flutter Application:

Images also play a critical part for every mobile application. They provide apps a more interactive, user-friendlier, and engaging appearance. Flutter, as of this writing in the year 2025, provides a number of means for adding images — whether local resources, network images, or from the device’s photo gallery. Below is a tutorial by BaseProgrammer.com for adding images in your Flutter apps.

Add Images in Flutter

Types of Images in Flutter

  • Asset Images – Images stored inside your project.
  • Network Images – Images loaded from the internet.
  • File Images – Images stored locally on the device.
  • Memory Images – Images stored in memory (e.g., base64).

Step 1: Adding Asset Images

  • Create an assets folder in your project root.
  • Place your image file inside it (example: assets/images/logo.png).
  • Add it in your pubspec.yaml:
flutter:
  assets:
    - assets/images/logo.png
  • Use it in your widget:
Image.asset("assets/images/logo.png", width: 150, height: 150);

Step 2: Adding Multiple Images

Instead of listing each image separately, you can load an entire folder:

flutter:
  assets:
    - assets/images/

Now any image inside assets/images/ can be used like this:

Image.asset("assets/images/home_banner.png");

Step 3: Using Network Images

For images hosted online:

Image.network(
  "https://baseprogrammer.com/wp-content/uploads/2025/01/flutter-image.png",
  width: 200,
  height: 200,
  loadingBuilder: (context, child, progress) {
    return progress == null
        ? child
        : const CircularProgressIndicator();
  },
  errorBuilder: (context, error, stackTrace) =>
      const Icon(Icons.error, size: 50, color: Colors.red),
);

Step 4: Using File Images

For images stored on the device (like from gallery or downloads):

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

Image.file(File("/storage/emulated/0/Download/sample.png"));

Step 5: Using Memory Images

Sometimes you’ll need to load an image from base64 string:

import 'dart:convert';
import 'dart:typed_data';

Uint8List bytes = base64Decode(base64ImageString);
Image.memory(bytes, fit: BoxFit.cover);

Example 6: Circular Profile Image

You can display profile pictures inside a circular widget using ClipOval or CircleAvatar:

CircleAvatar(
  radius: 50,
  backgroundImage: AssetImage("assets/images/profile.png"),
);

Example 7: Background Image with Decoration

Container(
  decoration: BoxDecoration(
    image: DecorationImage(
      image: AssetImage("assets/images/bg.png"),
      fit: BoxFit.cover,
    ),
  ),
  child: Center(
    child: Text(
      "Welcome to BaseProgrammer",
      style: TextStyle(color: Colors.white, fontSize: 24),
    ),
  ),
);

Best Practices for Add Images in Flutter 2025

  • ✅ Use SVG for icons/illustrations (with flutter_svg package).
  • ✅ Compress images before adding them to assets.
  • ✅ Prefer network caching libraries (like cached_network_image).
  • ✅ Use BoxFit for better scaling:
Image.asset(
  "assets/images/logo.png",
  fit: BoxFit.cover, // contain, fill, fitWidth, etc.
);

Example: Adding Logo in HomePage

import 'package:flutter/material.dart';

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text("BaseProgrammer - Image Example")),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Image.asset("assets/images/logo.png", width: 120),
            const SizedBox(height: 20),
            Image.network("https://baseprogrammer.com/images/banner.png"),
          ],
        ),
      ),
    );
  }
}
