Get Started: Install on Linux

System requirements

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

  • Operating Systems: Linux (64-bit)
  • Disk Space: 600 MB (does not include disk space for IDE/tools).
  • Tools: Flutter depends on these command-line tools being available in your environment.
    • bash, mkdir, rm, git, curl, unzip, which

Get the Flutter SDK

  1. Download the following installation bundle to get the latest beta release of the Flutter SDK (for other release channels, and older builds, see the SDK archive page.):

  2. Extract the file in the desired location, e.g.: 
    $ cd ~/development
$ tar xf ~/Downloads/flutter_linux_xxx.tar.xz
  3. Add the flutter tool to your path: 
    $ export PATH=`pwd`/flutter/bin:$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.

You are now ready to run Flutter commands!

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:

$ 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 (shown in bold text).

For example:

[-] Android toolchain - develop for Android devices
    • Android SDK at /Users/obiwan/Library/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 following sections describe how to perform these tasks and finish the setup process.

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 Get the Flutter SDK. 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:
$ export PATH=[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin:$PATH

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

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

$ echo $PATH

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. 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.
  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.
