What it does

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

Its SKILL.md is about 1.4k 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 Flutter, Android, Visual Studio Code 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 Windows machine to run
  • Deploy Flutter applications for Windows desktop

Example prompts

  • “/flutter-setting-up-on-windows”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Execute flutter doctor -v.
  2. Review the output for missing dependencies or path issues.
  3. Resolve any flagged errors before proceeding to tooling setup.

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
    • openssl

    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 Windows loads about 1.4k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 585 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

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.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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 Flutter for Windows Development

Contents

Core Requirements

Configure the Windows environment to support both Flutter framework execution and native C/C++ compilation. Differentiate strictly between Visual Studio (required for Windows desktop C++ compilation) and VS Code (the recommended Dart/Flutter code editor).

Workflow: Installing and Configuring the SDK

Follow this sequential workflow to initialize the Flutter SDK on a Windows machine.

  • Download the latest stable Flutter SDK for Windows.
  • Extract the SDK to a directory with standard user privileges (e.g., C:\src\flutter). Do not install in protected directories like C:\Program Files\.
  • Copy the absolute path to the Flutter SDK's bin directory.
  • Open Windows Environment Variables settings and append the bin directory path to the system or user PATH variable.
  • Open a new terminal session to apply the PATH changes.
  • Feedback Loop: Run validator -> review errors -> fix.
    1. Execute flutter doctor -v.
    2. Review the output for missing dependencies or path issues.
    3. Resolve any flagged errors before proceeding to tooling setup.

Workflow: Configuring Tooling and IDEs

  • Install Visual Studio (not VS Code).
  • Select and install the Desktop development with C++ workload during the Visual Studio installation process. This is mandatory for compiling Windows desktop applications.
  • Install your preferred code editor (VS Code, Android Studio, or IntelliJ).
  • Install the official Flutter and Dart extensions/plugins within your chosen editor.

Workflow: Configuring Target Platforms

Apply conditional logic based on the specific platform you are targeting for development.

If targeting Windows Desktop:

  • Ensure the Visual Studio C++ workload is fully updated.
  • Restart your IDE so it detects the Windows desktop device.
  • To disable platforms you do not intend to compile for, execute flutter config --no-enable-<platform> (e.g., flutter config --no-enable-windows-desktop).

If targeting Android on Windows:

  • For physical devices: Enable Developer Options and USB debugging on the device. Install the specific OEM USB drivers for Windows.
  • For emulators: Open the Android Virtual Device (AVD) manager. Under "Emulated Performance" -> "Graphics acceleration", select an option specifying "Hardware" to enable hardware acceleration.
  • Verify the device connection by running flutter devices.

Workflow: Building and Packaging for Windows

To distribute a Windows desktop application, assemble the compiled executable and its required dependencies into a single distributable archive.

  • Execute flutter build windows to compile the release build.
  • Navigate to build\windows\runner\Release\.
  • Create a new staging directory for the distribution zip.
  • Copy the following assets from the Release directory into the staging directory:
    • The application executable (.exe).
    • All generated .dll files.
    • The entire data directory.
  • Copy the required Visual C++ redistributables into the staging directory alongside the executable:
    • msvcp140.dll
    • vcruntime140.dll
    • vcruntime140_1.dll
  • Compress the staging directory into a .zip file for distribution.

Workflow: Generating and Installing Certificates

If you require a self-signed certificate for MSIX packaging or local testing, use OpenSSL.

  • Install OpenSSL and add its bin directory to your PATH environment variable.
  • Generate a private key: openssl genrsa -out mykeyname.key 2048
  • Generate a Certificate Signing Request (CSR): openssl req -new -key mykeyname.key -out mycsrname.csr
  • Generate the signed certificate (CRT): openssl x509 -in mycsrname.csr -out mycrtname.crt -req -signkey mykeyname.key -days 10000
  • Generate the .pfx file: openssl pkcs12 -export -out CERTIFICATE.pfx -inkey mykeyname.key -in mycrtname.crt
  • Install the .pfx certificate on the local Windows machine. Place it in the Certificate Store under Trusted Root Certification Authorities prior to installing the application.

Examples

Windows Distribution Directory Structure

When assembling your Windows build for distribution, ensure the directory structure strictly matches the following layout before zipping:

text
Release_Archive/
│   my_flutter_app.exe
│   flutter_windows.dll
│   msvcp140.dll
│   vcruntime140.dll
│   vcruntime140_1.dll
│
└───data/
    │   app.so
    │   icudtl.dat
    │   ...
