Get Started: Install on Windows

System requirements

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

  • Operating Systems: Windows 7 or later (64-bit)
  • Disk Space: 400 MB (does not include disk space for Android Studio).
  • Tools: Flutter depends on these command-line tools being available in your environment.

    • Git for Windows (with the Use Git from the Windows Command Prompt option)

      If Git for Windows is already installed, make sure you can run git commands from the Command Prompt or PowerShell.

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 repository:

$ git clone -b beta https://github.com/flutter/flutter.git

To update an existing version of Flutter, see Upgrading Flutter

Update your path

To run the flutter command in any terminal session, you need to add it to your PATH environment variable:

  • Go to “Control Panel > User Accounts > User Accounts > Change my environment variables”
  • 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.

Reboot Windows to fully apply this change.

Run flutter doctor

Open a new Command Prompt or PowerShell window and run the following command to see if there are any dependencies you need to install to complete the setup:

$ flutter doctor

Run this command in either a Command Prompt or PowerShell window. Currently, Flutter does not support third-party shells like Git Bash.

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:

[-] Android toolchain - develop for Android devices
    • Android SDK at D:\Android\sdk
    ✗ Android SDK is missing command line tools; download from https://goo.gl/XxQghQ
    • Try re-installing or updating your Android SDK,
      visit https://flutter.io/setup/#android-setup for detailed instructions.

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.

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.

Android setup

Install Android Studio

  1. Download and install Android Studio.

  2. 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.

  6. Verify the AVD configuration is correct, and select Finish.

    For details on the above steps, see Managing AVDs.

  7. 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.
  8. Start your app by running flutter run. The connected device name is Android SDK built for <platform>, where platform is the chip family, such as x86.
