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.
Shared libraries: Flutter

Get the Flutter SDK
On Linux, you have two ways you can install Flutter.
Install Flutter using snapd
The easiest way to install Flutter on Linux is by using snapd. For more information, see Installing snapd.
Once you have snapd, you can install Flutter using the Snap Store, or at the command line:
$ sudo snap install flutter --classic
Install Flutter manually
If you don’t have
snapd, or can’t use it, you can
install Flutter using the following steps.
Download the following installation bundle to get the latest stable release of the Flutter SDK:
For other release channels, and older builds, see the SDK releases page.
Extract the file in the desired location, for example:
$ cd ~/development $ tar xf ~/Downloads/flutter_linux_vX.X.X-stable.tar.xz
If you don’t want to install a fixed version of the installation bundle, you can skip steps 1 and 2. Instead, get the source code from the Flutter repo on GitHub with the following command:
$ git clone https://github.com/flutter/flutter.git
You can also change branches or tags as needed. For example, to get just the stable version:
$ git clone https://github.com/flutter/flutter.git -b stable
fluttertool to your path:
$ export PATH="$PATH:`pwd`/flutter/bin"
This command sets your
PATHvariable for the current terminal window only. To permanently add Flutter to your path, see Update your path.
Optionally, pre-download development binaries:
fluttertool downloads platform-specific development binaries as needed. For scenarios where pre-downloading these artifacts is preferable (for example, in hermetic build environments, or with intermittent network availability), iOS and Android binaries can be downloaded ahead of time by running:
$ flutter precache
For additional download options, see
flutter help precache.
You are now ready to run Flutter commands!
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
$ 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 might need to install or further tasks to perform (shown in bold text).

The following sections describe how to perform these tasks and finish the setup process.
Once you have installed any missing dependencies, run the
command again to verify that you’ve set everything up correctly.
Update your path
You can update your PATH variable for the current session 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:
- Determine the path of your clone of the Flutter SDK. You need this in Step 3.
- Open (or create) the
rcfile for your shell. For example, Linux uses the Bash shell by default, so edit
$HOME/.bashrc. If you are using a different shell, the file path and filename will be different on your machine.
Add the following line and change
[PATH_OF_FLUTTER_GIT_DIRECTORY]to be the path of your clone of the Flutter git repo:
$ export PATH="$PATH:[PATH_OF_FLUTTER_GIT_DIRECTORY]/bin"
source $HOME/.<rc file>to refresh the current window, or open a new terminal window to automatically source the file.
Verify that the
flutter/bindirectory is now in your PATH by running:
$ echo $PATH
Verify that the
fluttercommand is available by running:
$ which flutter
Update path directly
In some cases, your distribution may not permanently acquire the path when using the above directions. When this occurs, you can change the environment variables file directly. These instructions require administrator privileges:
Determine the path of your clone of the Flutter SDK.
etcdirectory at the root of the system, and open the
profilefile with root privileges.
$ sudo nano /etc/profile
Update the PATH string with the location of your Flutter SDK directory.
if [ "`id -u`" -eq 0 ]; then PATH="..." else PATH="/usr/local/bin:...:[PATH_OF_FLUTTER_GIT_DIRECTORY]/bin" fi export PATH
- End the current session or reboot your system.
Once you start a new session, verify that the
fluttercommand is available by running:
$ which flutter
Install Android Studio
- Download and install Android Studio.
- Start Android Studio, and go through the ‘Android Studio Setup Wizard’. This installs the latest Android SDK, Android SDK Command-line Tools, and Android SDK Build-Tools, which are required by Flutter when developing for Android.
flutter doctorto confirm that Flutter has located your installation of Android Studio. If Flutter cannot locate it, run
flutter config --android-studio-dir <directory>to set the directory that Android Studio is installed to.
Set up your Android device
To prepare to run and test your Flutter app on an Android device, you need an Android device running Android 4.1 (API level 16) or higher.
- Enable Developer options and USB debugging on your device. Detailed instructions are available in the Android documentation.
- Windows-only: Install the Google USB Driver.
- Using a USB cable, plug your phone into your computer. If prompted on your device, authorize your computer to access your device.
- In the terminal, run the
flutter devicescommand to verify that Flutter recognizes your connected Android device. By default, Flutter uses the version of the Android SDK where your
adbtool is based. If you want Flutter to use a different installation of the Android SDK, you must set the
ANDROID_SDK_ROOTenvironment 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:
- Enable VM acceleration on your machine.
- Launch Android Studio, click the AVD Manager
icon, and select Create Virtual Device…
- In older versions of Android Studio, you should instead launch Android Studio > Tools > Android > AVD Manager and select Create Virtual Device…. (The Android submenu is only present when inside an Android project.)
- If you do not have a project open, you can choose Configure > AVD Manager and select Create Virtual Device…
- Choose a device definition and select Next.
- 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.
- 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.
Agree to Android Licenses
Before you can use Flutter, you must agree to the licenses of the Android SDK platform. This step should be done after you have installed the tools listed above.
Make sure that you have a version of Java 8 installed and that your
JAVA_HOMEenvironment variable is set to the JDK’s folder.
Android Studio versions 2.2 and higher come with a JDK, so this should already be done.
- Open an elevated console window and run the following command to begin
$ flutter doctor --android-licenses
- Review the terms of each license carefully before agreeing to them.
- Once you are done agreeing with licenses, run
flutter doctoragain to confirm that you are ready to use Flutter.
Additional Linux requirements
For Linux desktop development, you need the following in addition to the Flutter SDK:
Run the following command
$ sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev
Enable desktop support
At the command line, perform the following command to enable desktop support
$ flutter config --enable-linux-desktop
For more information, see Desktop support for Flutter
Flutter has support for building web applications in the
stable channel. Any app created in Flutter 2 automatically
builds for the web. To add web support to an existing app, follow
the instructions on Building a web application with Flutter
when you’ve completed the setup above.
Set up your preferred editor.
