In this tutorial we will learn to show image in flutter. In flutter there is two types of images we can show one is asset image and other one is network image.
To use the images in flutter we have Image
class which supports both local and remote images. For asset images we need to define it in pubspec.yaml
first. Asset images are images which is stored locally in app directory and Network images are images which is stored in server. We can access Asset images using AssetImage
class or Image.asset
class.
Display remote image in flutter
Remote image or network image can be displayed easily in flutter application using Image.network
method which accept first parameter as URL of image and other parameters for configuration of image.
Let’s understand with an example
Step 1 : Create flutter project
Very first step is to create the fluter application using command line tool or in Android studio.
flutter create example_app
This will create a new project with name my_app then go in to the folder .
Step 2 : Create a simple widget
Now, Create a simple stateless widget to show the image and it will consist a container and center widget to center the image as below
File : lib/remoteimagedemo.dart
import 'package:flutter/material.dart';
class RemoteImageDemo extends StatelessWidget {
const RemoteImageDemo({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
// TODO: implement build
return Container(
color: Colors.white,
child: Center(
child: Image.network('https://picsum.photos/200'),
),
);
}
}
Step 3: Import and use the widget in main
We just created a new widget with name remoteimagedemo
, now we are going to use it in our main.dart file as below
import 'package:example_app/remoteimagedemo.dart';
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const RemoteImageDemo(),
);
}
}
Step 4: Run the project
Simply run the project using command line or in android studio to check the implementation.
flutter run lib/main.dart
