What it does

Flutter Setting Up On Linux is an agent skill from btwld/superdeck. Sets up a Linux environment for Flutter development. Use when configuring a Linux machine to run, build, or deploy Flutter applications.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering Cross-platform mobile apps. It works with Linux, Flutter and C++. The repository describes itself as: Presentation slides for Flutter with Flutter. The licence is BSD-3-Clause.

When your agent uses it

  • Configuring a Linux machine to run
  • Deploy Flutter applications

Example prompts

  • “/flutter-setting-up-on-linux”

What it can do on your machine

Read from SKILL.md and the folder at commit 815a746. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • apt-get
    • flutter

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Flutter Setting Up On Linux loads about 1.1k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 419 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Setting Up a Linux Environment for Flutter Development

Contents

System Dependencies

To build and run Flutter applications on a Linux desktop, install the required C/C++ toolchain and system libraries. Flutter relies on dart:ffi to interface with Linux system calls and the GTK framework for UI rendering.

Required packages for Debian/Ubuntu-based distributions:

  • Core Utilities: curl, git, unzip, xz-utils, zip
  • Build Tools: clang, cmake, ninja-build, pkg-config
  • Libraries: libglu1-mesa, libgtk-3-dev, libstdc++-12-dev

Workflow: Configuring the Linux Toolchain

Follow this sequential workflow to prepare the Linux host for Flutter desktop development.

Task Progress:

  • 1. Update package lists and upgrade existing packages.
  • 2. Install core utilities and build dependencies.
  • 3. Configure IDE/Editor with Flutter support.
  • 4. (Conditional) Enable Linux support on ChromeOS.

1. Update and Install Dependencies Execute the following command to install all required packages on Debian/Ubuntu systems:

bash
sudo apt-get update -y && sudo apt-get upgrade -y
sudo apt-get install -y curl git unzip xz-utils zip libglu1-mesa clang cmake ninja-build pkg-config libgtk-3-dev libstdc++-12-dev

2. Conditional: ChromeOS Setup

  • If developing on a Chromebook: Turn on Linux support in the ChromeOS settings. Ensure the Linux container is fully updated using the apt-get commands above before proceeding.

3. IDE Configuration Install Visual Studio Code, Android Studio, or an IntelliJ-based IDE. Install the official Dart and Flutter extensions/plugins to enable language server features and debugging capabilities.

Workflow: Validating the Environment

Run this feedback loop to ensure the toolchain is correctly recognized by the Flutter SDK.

Task Progress:

  • 1. Run environment validator.
  • 2. Verify connected Linux devices.
  • 3. Resolve toolchain errors.

1. Run Validator Execute the Flutter diagnostic tool with verbose output:

bash
flutter doctor -v

2. Review and Fix (Feedback Loop)

  • If errors exist under the "Linux toolchain" section: Review the missing dependencies, install the flagged packages, and re-run flutter doctor -v. Repeat until the Linux toolchain section passes.

3. Verify Device Availability Ensure the Linux desktop is recognized as a valid deployment target:

bash
flutter devices

Expected Output: At least one entry must display with the platform marked as linux.

Workflow: Preparing for Distribution (Snapcraft)

When preparing a release build for the Snap Store, configure the Snapcraft build environment.

Task Progress:

  • 1. Install Snapcraft and LXD.
  • 2. Configure LXD.
  • 3. Build the Snap package.

1. Install Build Tools

bash
sudo snap install snapcraft --classic
sudo snap install lxd

2. Configure LXD Initialize LXD and add the current user to the lxd group:

bash
sudo lxd init
sudo usermod -a -G lxd <your_username>

Note: Log out and log back in to apply the group changes.

3. Build the Snap Navigate to the project root containing the snap/snapcraft.yaml file and execute the build:

bash
snapcraft --use-lxd

Examples

Baseline snapcraft.yaml Configuration

Use this template for the <project_root>/snap/snapcraft.yaml file when packaging a Flutter Linux app for the Snap Store.
