In this article, we will delve into a step-by-step guide on how to set up Flutter on Ubuntu 22.04 LTS. Flutter, an open-source UI software development kit from Google, is widely used by developers and organizations globally to create high-quality native interfaces on iOS, Android, and Google Fuchsia.

Updating System Packages

First, we need to make sure all the system packages are up-to-date. Use the following commands:

sudo apt update
sudo apt upgrade

Installing Dependencies

Next, install the required dependencies with the following command:

sudo apt install curl file git unzip xz-utils zip libglu1-mesa

Downloading and Installing Flutter

To download the latest stable release of Flutter SDK, use:

wget https://storage.googleapis.com/flutter_infra_release/releases/stable/linux/flutter_linux_3.16.9-stable.tar.xz

After download, extract the file to a location of your choice, such as ~/development, using:

tar xf ~/Downloads/flutter_linux_3.16.9-stable.tar.xz -C ~/development

Adding Flutter to PATH

For Flutter commands to work in your terminal, you need to add Flutter to your PATH. You can do this temporarily using:

export PATH="$PATH:`pwd`/flutter/bin"

For a permanent solution, add the above export command to your .bashrc or .profile file. Reload the shell configuration afterward using either:

source ~/.bashrc

Or:

source ~/.profile

Running Flutter Commands

With Flutter installed, validate the setup and check for any missing dependencies using:

flutter doctor

If you plan to develop for Android, agree to the Android SDK licenses with:

flutter doctor --android-licenses

Verifying Installation

To verify the installation, create and run a new Flutter project using:

flutter create my_flutter_app
cd my_flutter_app
flutter run

If everything went according to plan, you should have successfully installed Flutter on Ubuntu 22.04 LTS.
