How to install flutter on Debian 12

Flutter is a powerful framework from Google for building cross-platform applications with a single codebase. Installing it on Debian 12 gives you the environment needed to develop for Android, iOS, web, and desktop.

Step 1: Update System Packages

Update your package lists and upgrade installed software:

sudo apt update && sudo apt upgrade -y

Step 2: Install Dependencies

Flutter requires some additional tools and libraries. Install them with:

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

Step 3: Download Flutter SDK

Move to /opt and download the latest stable Flutter SDK:

cd /opt
sudo curl -O https://storage.googleapis.com/flutter_infra_release/releases/stable/linux/flutter_linux_3.24.3-stable.tar.xz

Extract the archive:

sudo tar xf flutter_linux_3.24.3-stable.tar.xz
