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), Cmd, PowerShell, where

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

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 and then add the flutter tool to your path:

> git clone
> setx PATH "%PATH%;<cd>\flutter\bin"

replacing <cd> with your current directory path. For example, setx PATH "%PATH%;C:\Users\obiwan\flutter\bin".

Run these commands in either a Cmd or PowerShell window. Flutter does not support third-party shells like Git Bash.

To update an existing version of Flutter, see Upgrading Flutter

Run flutter doctor

Open a new Cmd 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

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 .

For example:

✗ Minimum supported Android SDK version is 25 but this system has 23. Please upgrade.

The first time you run the flutter command, 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. See IntelliJ 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

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 IntelliJ plug-ins for a rich IDE experience supporting editing, running, and debugging Flutter apps. See IntelliJ Setup for detailed steps.

Android setup

This step is optional, and can be performed at any time before using Flutter to develop apps for Android.

Install Android Studio

To develop Flutter apps for Android, you can use a Mac, Windows, or Linux (64-bit) machine:

  1. Install Android Studio.

    Flutter requires the latest Android SDK and Android SDK Platform-Tools packages. You can verify these are up-to-date in Android Studio>Configure>SDK Manager, as described in Update the IDE and SDK Tools.

  2. Start Android Studio.

Set up your Android device

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

  1. Enable developer mode on your device by visiting Settings>About phone and tapping the Build number line seven times.
  2. In Settings>Developer options, enable USB debugging.
  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.
  5. 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.
