What it does
Flutter Setting Up On macOS is an agent skill from btwld/superdeck. Sets up a macOS environment for Flutter development. Use when configuring a macOS machine to run, build, or deploy Flutter applications for iOS or macOS.
Its SKILL.md is about 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 macOS, Flutter, iOS and Xcode. The repository describes itself as: Presentation slides for Flutter with Flutter. The licence is BSD-3-Clause.

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:
flutter
xcodebuild
gem
sh
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 macOS loads about 1k tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 447 words of instructions outside code blocks.
Always· name and description, kept in context so the agent knows when to use it
~45
When it runs· the whole SKILL.md, loaded when a task matches
~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.

Setting Up a macOS Environment for Flutter Development
Existing SuperDeck checkout
Use fvm flutter and fvm dart with the SDK pinned in .fvmrc, rather than a global Flutter installation. Inspect fvm flutter doctor -v and xcode-select -p before changing machine tooling. Install or change Xcode/CocoaPods only when a diagnosed build requirement calls for it; do not upgrade a working toolchain as a routine setup step. The root AGENTS.md contains the workspace bootstrap and macOS launch commands.
Ensure the following baseline requirements are met before configuring the macOS-specific toolchain:
macOS operating system.
Flutter SDK installed and added to the system PATH.
Active internet connection for downloading toolchains and dependencies.
Tooling Configuration
macOS desktop development requires specific Apple toolchains to compile and debug native Swift and Objective-C code.
Xcode: Required for compiling macOS desktop applications.
CocoaPods: Required for managing native dependencies used by Flutter plugins.
Workflow: Configuring macOS Tooling
Copy and follow this checklist to configure the macOS build environment.
Install Xcode: Install the latest version of Xcode from the Mac App Store or the Apple Developer portal.
Configure Command-Line Tools: Link the Xcode command-line tools to the installed Xcode version. Run the following command in the terminal:bash
sudo sh -c 'xcode-select -s /Applications/Xcode.app/Contents/Developer && xcodebuild -runFirstLaunch'
Conditional: If Xcode is installed in a custom directory, replace /Applications/Xcode.app with the correct absolute path.
Accept Xcode Licenses: Accept the required developer licenses by running:bash
sudo xcodebuild -license
Read and agree to the prompts.
Install CocoaPods: Install CocoaPods to handle native macOS plugin dependencies.bash
sudo gem install cocoapods
Conditional: If CocoaPods is already installed, ensure it is updated to the latest version (sudo gem update cocoapods).

Workflow: Validating the Environment
Execute this feedback loop to ensure the environment is correctly configured for macOS desktop development.
Run Validator: Execute the Flutter diagnostic tool with verbose output:bash
flutter doctor -v
Review Errors: Check the Xcode section in the output.
Fix & Retry: If errors or missing components are reported under the Xcode section, resolve them according to the output instructions, then re-run flutter doctor -v until the Xcode section passes.
Verify Device Availability: Confirm that Flutter recognizes the macOS desktop as a valid deployment target:bash
flutter devices
Success Criteria: The output must contain at least one entry with macos listed as the platform.
Troubleshooting
If the validation workflow fails, apply the following resolutions:
Missing Command-Line Tools: If flutter doctor reports missing tools, ensure the xcode-select command was run with sudo and points to the correct .app directory.
CocoaPods Not Found: If CocoaPods is installed but not detected, verify that your Ruby gem binary path is included in your shell's PATH environment variable.
Device Not Listed: If flutter devices does not list macos, ensure desktop support is enabled in your Flutter configuration:bash
