Install Flutter SDK via git clone and configure for all platforms
What this skill does
# Install Flutter from Git
This skill guides you through installing the Flutter SDK using `git clone` and setting up the environment for Web, Mobile, and Desktop development.
## 1. Prerequisites (All Platforms)
Ensure you have the following installed:
- **Git**: [Install Git](https://git-scm.com/downloads)
- **Curl/Unzip** (macOS/Linux usually have these; Windows usually needs Git Bash or similar)
## 2. Install Flutter SDK
### macOS / Linux
Open your terminal and run the following commands to clone the stable branch of the Flutter SDK.
```bash
# Create a directory for development (e.g., ~/development)
mkdir -p ~/development
cd ~/development
# Clone the Flutter SDK
git clone https://github.com/flutter/flutter.git -b stable
```
### Windows
Open PowerShell or Command Prompt.
```powershell
# Create a directory for development (e.g., C:\src)
mkdir C:\src
cd C:\src
# Clone the Flutter SDK
git clone https://github.com/flutter/flutter.git -b stable
```
## 3. Add Flutter to PATH
To run `flutter` commands from any terminal, you must add the SDK's `bin` directory to your PATH.
### macOS (Zsh) / Linux (Bash/Zsh)
1. Open your shell configuration file (e.g., `~/.zshrc`, `~/.bashrc`, or `~/.zshenv`).
2. Add the following line (replace `~/development/flutter` with your actual path):
```bash
export PATH="$PATH:$HOME/development/flutter/bin"
```
3. Refresh your current terminal:
```bash
source ~/.zshrc # or ~/.bashrc
```
### Windows
1. Press `Win + S`, type "env", and select **Edit the system environment variables**.
2. Click **Environment Variables**.
3. Under **User variables**, select **Path** and click **Edit**.
4. Click **New** and add the full path to `flutter\bin` (e.g., `C:\src\flutter\bin`).
5. Click **OK** on all windows.
6. Restart your terminal/PowerShell.
## 4. Verify Installation
Run the following command to check for missing dependencies:
```bash
flutter doctor
```
## 5. Platform Setup
### Web (Chrome)
1. **Install Chrome**: Ensure Google Chrome is installed.
2. **Enable Web Support** (usually enabled by default):
```bash
flutter config --enable-web
```
3. **Verify**: Run `flutter devices` to see "Chrome" listed.
### Mobile (iOS & Android)
#### iOS (macOS only)
1. **Install Xcode**: Download from the Mac App Store.
2. **Configure Command Line Tools**:
```bash
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
sudo xcodebuild -runFirstLaunch
```
3. **Install CocoaPods** (for dependency management):
```bash
sudo gem install cocoapods
```
4. **Simulator**: Open via `open -a Simulator`.
#### Android (All Operating Systems)
1. **Install Android Studio**: [Download here](https://developer.android.com/studio).
2. **Install SDK Components**:
- Open Android Studio -> SDK Manager.
- Install **Android SDK Platform-Tools**.
- Install **Android SDK Command-line Tools (latest)**.
3. **Accept Licenses**:
```bash
flutter doctor --android-licenses
```
(Press `y` to accept all licences).
4. **Emulator**: Create a device in AVD Manager.
### Desktop (macOS, Windows, Linux)
#### macOS Desktop
1. **Install Xcode**: (Same as iOS steps above).
2. **Enable macOS**:
```bash
flutter config --enable-macos-desktop
```
#### Windows Desktop
1. **Install Visual Studio** (not VS Code): [Download VS Community](https://visualstudio.microsoft.com/downloads/).
2. **Workloads**: When installing, select **Desktop development with C++**.
3. **Enable Windows**:
```bash
flutter config --enable-windows-desktop
```
#### Linux Desktop
1. **Install Dependencies** (Ubuntu/Debian example):
```bash
sudo apt-get update
sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev liblzma-dev
```
2. **Enable Linux**:
```bash
flutter config --enable-linux-desktop
```
## 6. Final Check
Run `flutter doctor` again to ensure all desired platforms have checkmarks.
```bash
flutter doctor -v
```

jfrog
IncludedInteract with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.
cupynumeric-migration-readiness
IncludedPre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.
alibabacloud-data-agent-skill
IncludedInvoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".
token-optimizer
IncludedReduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
resend-cli
IncludedUse this skill when the task is specifically about operating Resend from an AI agent, terminal session, or CI job via the official resend CLI: installing/authenticating the CLI, sending/listing/updating/cancelling emails, batch sends, domains and DNS, webhooks and local listeners, inbound receiving, contacts, topics, segments, broadcasts, templates, API keys, profiles, or debugging Resend CLI/API failures. Trigger on mentions of Resend CLI, `resend`, `resend doctor`, `resend emails send`, `resend domains`, `resend webhooks listen`, `resend emails receiving`, or agent-friendly terminal automation.
alibabacloud-odps-maxframe-coding
IncludedUse this skill for MaxFrame SDK development and documentation navigation on Alibaba Cloud MaxCompute (ODPS). Helps answer MaxFrame API, concept, official example, and supported pandas API questions; create data processing programs; read/write MaxCompute tables; debug jobs (remote or local); and build custom DPE runtime images. Trigger when users mention MaxFrame, MaxCompute with MaxFrame, ODPS table processing, DPE runtime, MaxFrame docs/examples, DataFrame/Tensor operations, or GPU runtime setup. Works for both English and Chinese queries about Alibaba Cloud data processing with MaxFrame.
