Get Started: Install on macOS

System requirements

To install and run Flutter, your development environment must meet these minimum requirements:

  • Operating Systems: macOS (64-bit)
  • Disk Space: 700 MB (does not include disk space for Xcode or Android Studio).
  • Tools: Flutter depends on these command-line tools being available in your environment.
    • bash , mkdir , rm , git , curl , unzip , which

Get the Flutter SDK

To get Flutter, use git to clone the repository and then add the flutter tool to your path. Running flutter doctor shows any remaining dependencies you may need to install.

Clone the repo

If this is the first time you’re installing Flutter on this machine, clone the beta branch of the repository and then add the flutter tool to your path:

The above command sets your PATH variable temporarily, for the current terminal window. To permanently add Flutter to your path, see Update your path.

To update an existing version of Flutter, see Upgrading Flutter.

Run flutter doctor

Run the following command to see if there are any dependencies you need to install to complete the setup:

This command checks your environment and displays a report to the terminal window. The Dart SDK is bundled with Flutter; it is not necessary to install Dart separately. Check the output carefully for other software you may need to install or further tasks to perform (shown in bold text).

The first time you run a flutter command (such as flutter doctor ), it downloads its own dependencies and compiles itself. Subsequent runs should be much faster.

The following sections describe how to perform these tasks and finish the setup process. You’ll see in flutter doctor output that if you choose to use an IDE, plugins are available for IntelliJ IDEA, Android Studio, and VS Code. See Editor Setup for the steps to install the Flutter and Dart plugins.

Once you have installed any missing dependencies, run the flutter doctor command again to verify that you’ve set everything up correctly.

The flutter tool uses Google Analytics to anonymously report feature usage statistics and basic crash reports. This data is used to help improve Flutter tools over time. Analytics is not sent on the very first run or for any runs involving flutter config , so you can opt out of analytics before any data is sent. To disable reporting, type flutter config —no-analytics and to display the current setting, type flutter config . See Google’s privacy policy:www.google.com/intl/en/policies/privacy.

Update your path

You can update your PATH variable for the current session only at the command line, as shown in Clone the Flutter repo. You’ll probably want to update this variable permanently, so you can run flutter commands in any terminal session.

The steps for modifying this variable permanently for all terminal sessions are machine-specific. Typically you add a line to a file that is executed whenever you open a new window. For example:

  1. Determine the directory where you placed the Flutter SDK. You will need this in Step 3.
  2. Open (or create) $HOME/.bash_profile . The file path and filename might be different on your machine.
  3. Add the following line and change [PATH_TO_FLUTTER_GIT_DIRECTORY] to be the path where you cloned Flutter’s git repo:

    Run source $HOME/.bash_profile to refresh the current window.

    Verify that the flutter/bin directory is now in your PATH by running:

    Editor setup

    Using the flutter command-line tools, you can use any editor to develop Flutter applications. Type flutter help at a prompt to view the available tools.

    We recommend using our plug-ins for a rich IDE experience supporting editing, running, and debugging Flutter apps. See Editor Setup for detailed steps.

    Platform setup

    macOS supports developing Flutter apps for both iOS and Android. Complete at least one of the two platform setup steps now, to be able to build and run your first Flutter app.

    iOS setup

    Install Xcode

    To develop Flutter apps for iOS, you need a Mac with Xcode 7.2 or newer:

      Install Xcode 7.2 or newer (via web download or the Mac App Store).

    Configure the Xcode command-line tools to use the newly-installed version of Xcode by running sudo xcode-select —switch /Applications/Xcode.app/Contents/Developer from the command line.

    This is the correct path for most cases, when you want to use the latest version of Xcode. If you need to use a different version, specify that path instead.

  1. Make sure the Xcode license agreement is signed by either opening Xcode once and confirming or running sudo xcodebuild -license from the command line.

With Xcode, you’ll be able to run Flutter apps on an iOS device or on the simulator.

Set up the iOS simulator

To prepare to run and test your Flutter app on the iOS simulator, follow these steps:

  1. On your Mac, find the Simulator via Spotlight or by using the following command:
  1. Make sure your simulator is using a 64-bit device (iPhone 5s or later) by checking the settings in the simulator’s Hardware > Device menu.
  2. Depending on your development machine’s screen size, simulated high-screen-density iOS devices may overflow your screen. Set the device scale under the Window > Scale menu in the simulator.
  3. Start your app by running flutter run .

Deploy to iOS devices

To deploy your Flutter app to a physical iOS device, you’ll need some additional tools and an Apple account. You’ll also need to set up physical device deployment in Xcode.

  1. Install homebrew.
  2. Open the terminal and run these commands to install the tools for deploying Flutter apps to iOS devices.

If any of these commands fails with an error, run brew doctor and follow the instructions for resolving the issue.

  1. Follow the Xcode signing flow to provision your project:
    1. Open the default Xcode workspace in your project by running open ios/Runner.xcworkspace in a terminal window from your Flutter project directory.
    2. In Xcode, select the Runner project in the left navigation panel.
    3. In the Runner target settings page, make sure your Development Team is selected under General > Signing > Team. When you select a team, Xcode creates and downloads a Development Certificate, registers your device with your account, and creates and downloads a provisioning profile (if needed).
      • To start your first iOS development project, you may need to sign into Xcode with your Apple ID.

        Development and testing is supported for any Apple ID. Enrolling in the Apple Developer Program is required to distribute your app to the App Store. View the differences between Apple membership types.
      • The first time you use an attached physical device for iOS development, you will need to trust both your Mac and the Development Certificate on that device. Select Trust in the dialog prompt when first connecting the iOS device to your Mac.

        Then, go to the Settings app on the iOS device, select General > Device Management and trust your Certificate.
      • If automatic signing fails in Xcode, verify that the project’s General > Identity > Bundle Identifier value is unique.
  2. Start your app by running flutter run .

Android setup

Note: Flutter relies on a full installation of Android Studio to supply its Android platform dependencies. However, you can write your Flutter apps in a number of editors; a later step will discuss that.

Install Android Studio

Download and install Android Studio.

Start Android Studio, and go through the ‘Android Studio Setup Wizard’. This will install the latest Android SDK, Android SDK Platform-Tools, and Android SDK Build-Tools, which are required by Flutter when developing for Android.

Set up your Android device

To prepare to run and test your Flutter app on an Android device, you’ll need an Android device running Android 4.1 (API level 16) or higher.

  1. Enable Developer options and USB debugging on your device. Detailed instructions are available in the Android documentation.
  2. Using a USB cable, plug your phone into your computer. If prompted on your device, authorize your computer to access your device.
  3. In the terminal, run the flutter devices command to verify that Flutter recognizes your connected Android device.
  4. Start your app by running flutter run .

By default, Flutter uses the version of the Android SDK where your adb tool is based. If you want Flutter to use a different installation of the Android SDK, you must set the ANDROID_HOME environment variable to that installation directory.

Set up the Android emulator

To prepare to run and test your Flutter app on the Android emulator, follow these steps:

  1. Enable VM acceleration on your machine.
  2. Launch Android Studio>Tools>Android>AVD Manager and select Create Virtual Device.
  3. Choose a device definition and select Next.
  4. Select one or more system images for the Android versions you want to emulate, and select Next. An x86 or x86_64 image is recommended.
  5. Under Emulated Performance, select Hardware — GLES 2.0 to enable hardware acceleration.

Verify the AVD configuration is correct, and select Finish.

For details on the above steps, see Managing AVDs.

  • In Android Virtual Device Manager, click Run in the toolbar. The emulator starts up and displays the default canvas for your selected OS version and device.
  • Start your app by running flutter run . The connected device name is Android SDK built for

    , where platform is the chip family, such as x86.

    How to install Flutter on Mac & Windows

    Subscribe to my newsletter and never miss my upcoming articles

    In this post, we’ll have an overview of Flutter, the latest buzz in the App Development market. Flutter is gaining popularity faster than any other framework. Some say it is Google’s answer to Facebook’s React Native, but that debate is for later. Let’s learn the basics of Flutter and how to start using it.

    What is Flutter?

    Flutter is Google’s portable UI toolkit for crafting high-quality native experiences for mobile, web, and desktop in record time. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.

    What does Flutter do?

    For users, Flutter makes beautiful app UIs come to life.

    For developers, Flutter lowers the bar to entry for building mobile apps. It speeds up the development of mobile apps and reduces the cost and complexity of app production across iOS and Android.

    For designers, Flutter helps deliver the original design vision, without loss of fidelity or compromises. It also acts as a productive prototyping tool.

    What technology is Flutter built with?

    Flutter is built with C, C++, Dart, and Skia (a 2D rendering engine). See this architecture diagram for a better picture of the main components.

    Why use Flutter?

    • Develop for iOS and Android from a single codebase
    • Do more with less code, even on a single OS, with a modern, expressive language and a declarative approach
    • Experiment by changing code and reloading as your app runs (with hot reload)
    • Fix crashes and continue debugging from where the app left off
    • Benefit from a rich set of Material Design and Cupertino (iOS-flavor) widgets built using Flutter’s own framework
    • Realize custom, beautiful, brand-driven designs, without the limitations of OEM widget sets

    How to Install Flutter on Windows?

    Minimum System Requirements

    • Operating Systems: Windows 7 or later [64-bit]
    • Disk Space: 400 MB
    • Git for Windows

    Get the Flutter SDK

    • Download Latest Flutter SDK here:
    • Unzip the downloaded zip in C:\flutter .
    • Locate flutter_console.bat inside the flutter directory and start it by double-clicking.

    Update your path

    If you wish to run Flutter commands in the regular Windows console, take these steps to add Flutter to the PATH environment variable:

    • From the Start search bar, type ‘env’ and select Edit environment variables for your account
    • Under User variables check if there is an entry called Path:
    • If the entry does exist, append the full path to flutter\bin using ; as a separator from existing values.
    • If the entry does not exist, create a new user variable named Path with the full path to flutter\bin as its value.

    Note that you will have to close and reopen any existing console windows for these changes to take effect.

    Run flutter doctor

    From a console window which has the Flutter directory in the path (see above), run the following command to see if there are any platform dependencies you need to complete the setup:

    This command checks your environment and displays a report of the status of your Flutter installation. Check the output carefully for other software you may need to install or further tasks to perform (shown in bold text).

    For example:

    Android Setup

    Flutter relies on a full installation of Android Studio to supply its Android platform dependencies. However, you can write your Flutter apps in a number of editors.

    Install Android Studio

    1. Download and install Android Studio.
    2. Start Android Studio, and go through the ‘Android Studio Setup Wizard‘. This installs the latest Android SDK, Android SDK Platform-Tools, and Android SDK Build-Tools, which are required by Flutter when developing for Android.

    Set up your Android device

    To prepare to run and test your Flutter app on an Android device, you’ll need an Android device running Android 4.1 (API level 16) or higher.

    1. Enable Developer Options and USB debugging on your device. Detailed instructions are available in the Android documentation.
    2. Windows-only: Install the Google USB Driver
    3. Using a USB cable, plug your phone into your computer. If prompted on your device, authorize your computer to access your device.
    4. In the terminal, run the flutter devices command to verify that Flutter recognizes your connected Android device.

    By default, Flutter uses the version of the Android SDK where your adb tool is based. If you want Flutter to use a different installation of the Android SDK, you must set the ANDROID_HOME environment variable to that installation directory.

    Install the Flutter and Dart plugins

    1. Start Android Studio.
    2. Open plugin preferences (File > Settings > Plugins).
    3. Select Browse repositories, select the Flutter plugin and click Install.
    4. Click Yes when prompted to install the Dart plugin.
    5. Click Restart when prompted.

    How to Install Flutter on MacOS?

    Minimum System Requirements

    • Operating Systems: macOS [64-bit]
    • Disk Space: 700 MB
    • Git for macOS

    Get the Flutter SDK

    • Download Latest Flutter SDK here:
    • Extract the file in the desired location e.g.
    • Add the flutter tool to your path. To do this, open your bash profile from your terminal (might need sudo)

    Add your flutter path to the $PATH variable in bash_profile.

    E.g. If you extracted flutter in your Applications folder, your path will be /Applications/flutter/bin . Add this to the existing $PATH variable by using : in between two paths. Once added, save and close the bash_profile . Run terminal again and check the $PATH by running

    You should see your Flutter path added to the $PATH

    • Run flutter precache in the terminal.

    Run flutter doctor

    Run the following command to see if there are any dependencies you need to install to complete the setup (for verbose output, add the -v flag):

    This command checks your environment and displays a report to the terminal window. The Dart SDK is bundled with Flutter; it is not necessary to install Dart separately. Check the output carefully for other software you may need to install or further tasks to perform (shown in bold text).

    For example: If you haven’t used Flutter before, you might see an output like this by running flutter doctor

    You can see there are several things to be done to begin using Flutter in this Mac. To correct these issues, let’s run the following commands

    Fix license issue in Android studio

    Fix iOS toolchain issues

    Install Xcode command line tools if you are on Mac OS Mojave
