How to install Flutter on Ubuntu 20.04 |18.04 | 21.04 Linux – Guide
Flutter is an open source SDK designed to program applications that work on multiple operating systems using a single code base, such as Android, iOS, Linux, Mac, Windows, Google Fuchsia and the web. Therefore, save developers time and labor to code an application according to the specific operating system. Flutter is developed by Google written in C, C++ and Dart.
Flutter Installation on Ubuntu 20.04 LTS Linux
Here, we are using Ubuntu 20.04 to install the Flutter UI framework, however the steps will be the same for Ubuntu 21.04 and 18.04, including Linux Mint, POP! OS, MX Linux and other Debian-based systems.
#Ist Method using Snap
Use Snap to install Flutter on Ubuntu 20.04 LTS
If you don’t want to go through several steps to install and set up flutter then simply run the SNAP command, a single command will define all the things needed to get started with this programming platform.
sudo snap install flutter – classic
To find out where the Flutter SDK is, run:
#2 Method using Tarball file
1. Run system update
Let’s first run the system update command before installing Flutter, this will update all packages already installed on our Ubuntu 20.04 Linux. In addition to updating the system repo cache.
sudo apt update
2. Install dependencies
There are some tools and libraries needed to use Flutter on Linux, such as Ubuntu. Therefore, before proceeding, use the command given below to install them.
sudo apt install file curl git unzip xz-utils zip libglu1-mesa clang cmake
ninja-build pkg-config libgtk-3-dev
Create a dedicated folder
Well, it’s a good idea to create a dedicated folder to store Flutter and keep things from getting messy up. For example, let’s create a directory called -myproject that you can use whatever you like.
3. Download the latest Flutter SDK
Next, we need the Flutter SDK tarball file. This we can easily download from their official page. Here is the link. Visit the page and select the latest version of Flutter to download.
Download the latest version of Flutter SDK for Linux
4. Install Flutter on Ubuntu 20.04 LTS
Change to the folder where you want to extract the downloaded flutter files. For example, here we have created a dedicated directory called -myproject and are using it.
cd my project
tar xvf ~ / Downloads / flutter_linux _ * – stable.tar.xz
In the above command, our downloaded Flutter tar file is inside the Downloads folder, that’s why we’ve provided the path to this.
5. Add vibration to the environment path
Well, to use the Flutter tool, we have to change to the extracted Flutter folder every time or we need to mention its full path. To remove this headache, just add your bin directory to the environment path, so you can access Flutter globally from anywhere in Terminal.
Edit bash profile
year ~ / .bashrc
This is the syntax to use:
export PATH = “$ PATH:/ bin ”
To replace in the command above with the actual path of the folder where you extracted Flutter.
For example, here we create a folder called myproject and under that we extract the folder. Therefore, the above command in our case will be:
nano ~ / .bashrc
At the final from the file, add the PATH in the following format:
export PATH = “$ PATH: ~ / myproject / flutter / bin”
Save the file by pressing Ctrl + O and then Ctrl + X.
Reload Terminal Session
Now update your current terminal session by closing and reopening the Terminal app as well.
Check if your Flutter folder is in your environment path or not
After confirming that the folder where you extracted Flutter is in the environment path, let’s verify that Flutter’s command line tools are working perfectly.
vibration – version
Check Flutter Version
6. Check for any missing addictions using the flutter doctor
Well, although we have successfully completed the installation along with the necessary dependencies. However, even in this case, something is missing to complete the configuration, this can be pointed out using Flutter’s medical command:
In the screenshot provided below, you can see that we are missing two things we need for the full setup: the Chrome browser, the Android toolset, and the Android Studio. Let’s install them in the next step.
Flutter Doctor on Ubuntu to check for errors
7. Get the Chrome browser
Run the following commands to install Chrome browser on your Ubuntu system.
wget -q -O – https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add –
sudo sh -c ‘echo “deb http://dl.google.com/linux/chrome/deb/ stable main ”>> /etc/apt/sources.list.d/google.list ‘
sudo apt update
sudo apt install google-chrome-stable
8. Install Android Studio on Ubuntu 20.04
Open your browser and download Android Studio for Linux. Visit the official page and select the Tarball archive.
Download Android Studio for Linux
Once the download is complete, go to the Downloads directory.
tar xvf android-studio – * – linux.tar.gz
Move the extracted file to the /opt directory.
sudo mv android-studio / opt /
Run Android Studio:
Then just follow the wizard.
(optional) If you want to create the Linux desktop shortcut and command in Android Studio, follow the link

Android Studio Settings
Select Appearance & Behavior > System Settings > Android SDK > SDK Tools
Check the box provided for “Android SDK Command Line Tools (Latest)” and press the OK button button.

10. Add command line tools to your environment

At the final from the file, add the following line
export PATH = $PATH: ~ / Android / Sdk / cmdline-tools / latest / bin
Save the file and reload bash. Or simply close Terminal and open it again.
source ~ / .bashrc
11. Agree to Android licenses
To use Flutter, the user must agree to the Android SDK platform licenses. Here is the command for it:
flutter doctor – android-licenses
Flutter Acceptance License
12. Recheck vibration requirements
Let’s double check that the Flutter dependencies were completed and the setup was successful.
Flutter installed Ubuntu 20.04
13. Define up an editor
Per up the editor, go to Android Studio, open any project, click File and select Settings.
There select “Plugins” and select Flutter to install it.
Install the Flutter plugin
14. Create Flutter Project
