In this tutorial, we will cover the basic setup required to start a Flutter project. By the end, you will have installed Flutter and set up an Integrated Development Environment (IDE) of your choice to start building your first Flutter app.
You will learn:
- How to install Flutter on your system
- How to setup an IDE for Flutter development
- How to create your first Flutter project
Prerequisites:
- Basic knowledge of programming
- A computer with internet connection
To install Flutter, you should have a system with these minimum requirements:
- Operating Systems: Windows 7 SP1 or later (64-bit), x86-64 based Linux, MacOS (64-bit)
- Disk Space: 1.64 GB (does not include disk space for IDE/tools).
- Tools: Flutter depends on these command-line tools being available in your environment.
- bash, mkdir, rm, git, curl, unzip, which
Download the stable release of the Flutter SDK from the Flutter SDK releases page. Select the version that corresponds with your operating system.
Extract the zip file and place the contained flutter in the desired installation location for the Flutter SDK (for example, C:\src\flutter
).
Add the flutter tool to your path. This process varies depending on the Operating System.
You can use any text editor combined with command-line tools, but IDEs, like Android Studio or VS Code, will give you a better experience.
Download and install Android Studio or Visual Studio Code.
After installing the IDE, you need to install Flutter and Dart plugins. These plugins will give you a rich set of powerful tools.
After setting up Flutter and the IDE, you are ready to create a new Flutter project:
Create New Flutter Project
.Flutter Application
and click Next
.Next
.Finish
and wait for the project to be created.import 'package:flutter/material.dart';
void main() {
runApp(
MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text('Hello World'),
),
body: Center(
child: Text('Hello World'),
),
),
),
);
}
In this code snippet, we import the Flutter Material library. Then we define a main
function that uses the runApp
function to run a Flutter app. The runApp
function takes a MaterialApp
widget. This widget is the root of your application and includes an AppBar
widget with a title and a Center
widget containing a Text
widget with 'Hello World'.
import 'package:flutter/material.dart';
void main() {
runApp(
MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text('Basic Layout'),
),
body: Column(
children: <Widget>[
Text('Item 1'),
Text('Item 2'),
Text('Item 3'),
],
),
),
),
);
}
In this example, we created a column of text widgets. The Column
widget takes a list of children and displays them vertically.
In this tutorial, we have covered how to install Flutter, how to set up an IDE for Flutter development, and how to create a basic Flutter project.
