How to Add Image from Assets Folder in Flutter App
Introduction
In Flutter, images can be added to a project from various sources, including the assets folder. Adding images from the assets folder is a straightforward process that requires some configuration and code. In this article, we will walk through the steps to add an image from the assets folder in a Flutter app.
Step 1: Declare the Image in the pubspec.yaml File
To use an image from the assets folder, we first need to declare it in the pubspec.yaml file. This file is used to manage dependencies and assets in a Flutter project. To declare an image, add the following code to the pubspec.yaml file:
“`yml
flutter:
assets:
– assets/image.png
“`
Replace “image.png” with the actual name of the image file.
Step 2: Create the Assets Folder and Add the Image
Next, we need to create the assets folder and add the image to it. The assets folder should be located in the root directory of the Flutter project. Create a new folder named “assets” and add the image file to it.
Step 3: Display the Image in the Flutter App
To display the image in the Flutter app, we can use the `Image.asset` widget. Here’s an example of how to use it:
“`dart
import ‘package:flutter/material.dart’;
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Center(
child: Image.asset(‘assets/image.png’),
),
),
);
}
}
“`
This code will display the image in the center of the screen.
Conclusion
In conclusion, adding an image from the assets folder in a Flutter app is a simple process that requires some configuration and code. By following the steps outlined in this article, you can easily add images to your Flutter project and display them on the screen.
