How to Install and Setup Flutter Development on Ubuntu and Other Linux
|
|||
|
|
======
|
|||
|
|
|
|||
|
|
Google’s UI toolkit Flutter is getting increasingly popular for creating cross-platform applications for the mobile, web and desktop.
|
|||
|
|
|
|||
|
|
[Flutter][1] is not a programming language but a software development kit. [Dart][2] is the programming language used underneath the Flutter SDK.
|
|||
|
|
|
|||
|
|
Flutter is the main framework behind Google’s open source Fuchsia OS, Google STADIA and many other software and mobile apps.
|
|||
|
|
|
|||
|
|
If you want to start developing with Flutter, this tutorial will help you to get your set-up ready on Ubuntu and hopefully other Linux distributions.
|
|||
|
|
|
|||
|
|
### Installing Flutter on Ubuntu and other Linux with Snap
|
|||
|
|
|
|||
|
|
The easiest way to install Flutter on Linux is by using Snap. If you are using Ubuntu, you already have got Snap. _**For other distributions, please make sure to [enable Snap support][3].**_
|
|||
|
|
|
|||
|
|
[Open a terminal][4] and use the following command in a terminal to install Flutter:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
sudo snap install flutter --classic
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
You’ll see something like this on your terminal:
|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|
Once the installation completes, it is time to verify it. Not just Flutter installation but also verify every dependency that needs to be satisfied for Flutter to function properly.
|
|||
|
|
|
|||
|
|
#### Verify Flutter dependencies
|
|||
|
|
|
|||
|
|
To verify that every dependency, for the correct work of Flutter, is installed, Flutter has a built-in option:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
flutter doctor
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
The process will start, looking like this:
|
|||
|
|
|
|||
|
|
![][6]
|
|||
|
|
|
|||
|
|
And it will be finishing like this:
|
|||
|
|
|
|||
|
|
![][7]
|
|||
|
|
|
|||
|
|
As you can see, we need Android Studio for working. So let’s install it. How do we do that? [Installing Android Studio on Linux][8] is also effortless with Snap.
|
|||
|
|
|
|||
|
|
#### Install and set up Android Studio
|
|||
|
|
|
|||
|
|
In a terminal, use the following command to get Android Studio installed:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
sudo snap install android-studio --classic
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
![][9]
|
|||
|
|
|
|||
|
|
Once installed, open Android Studio from our operating system menu.
|
|||
|
|
|
|||
|
|
![][10]
|
|||
|
|
|
|||
|
|
You are almost done. It’s time for configuring Android Studio.
|
|||
|
|
|
|||
|
|
![][11]
|
|||
|
|
|
|||
|
|
Click next and select standard if you don’t want to complicate things.
|
|||
|
|
|
|||
|
|
![][12]
|
|||
|
|
|
|||
|
|
Select your preferred theme (I like the Dark one).
|
|||
|
|
|
|||
|
|
![][13]
|
|||
|
|
|
|||
|
|
Verify that everything is OK and click on Next.
|
|||
|
|
|
|||
|
|
![][14]
|
|||
|
|
|
|||
|
|
Finally, hit the Finish button.
|
|||
|
|
|
|||
|
|
![][15]
|
|||
|
|
|
|||
|
|
And wait until the download is finished.
|
|||
|
|
|
|||

### Creating a sample Hello World Flutter app
|
|||
|
|
|
|||
|
|
In Android Studio, go to Projects and select New Flutter Project. Flutter SDK path will be set by default.
|
|||
|
|
|
|||
|
|
![][17]
|
|||
|
|
|
|||
|
|
And here is where the magic starts to appear because this is where you set your project name, which in this case it will be called hello_world.
|
|||
|
|
|
|||
|
|
Let’s select the three available platforms: **Android, iOS, and Web**. And finally, click on Finish.
|
|||
|
|
|
|||
|
|
![][18]
|
|||
|
|
|
|||
|
|
The principal file in the projects is located in `lib/main.dart`, as is shown in the next image.
|
|||
|
|
|
|||
|
|
![][19]
|
|||
|
|
|
|||
|
|
Once selected, erase everything contained inside the file and change it for this sample code:
|
|||
|
|
|
|||
|
|
```

import 'package:flutter/material.dart';
|
|||
|
|
|
|||
|
|
void main() => runApp(MyApp());
|
|||
|
|
|
|||
|
|
class MyApp extends StatelessWidget {
|
|||
|
|
@override
|
|||
|
|
Widget build(BuildContext context) {
|
|||
|
|
return MaterialApp(
|
|||
|
|
title: 'Welcome to Flutter',
|
|||
|
|
home: Scaffold(
|
|||
|
|
appBar: AppBar(
|
|||
|
|
title: const Text('Welcome to Flutter'),
|
|||
|
|
),
|
|||
|
|
body: const Center(
|
|||
|
|
child: Text('Hello World'),
|
|||
|
|
),
|
|||
|
|
),
|
|||
|
|
);
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
It’s important to say that this is only for showing you how Flutter works, in case you’re convinced about learning this beautiful and incredible language, here is the [Documentation][20] to see more about it. **Try** it!
|
|||
|
|
|
|||
|
|
Finally, select **Chome Web** device and do click on the **Run** button, as is shown below; and see the magic!
|
|||
|
|
|
|||
|
|
![][21]
|
|||
|
|
|
|||
|
|
It’s incredible how fast you can create a Flutter project. Say hello to your Hello World project.

|||

|||
|
|
|
|||
|
