System requirements

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

Operating Systems: Windows 10 or later (64-bit), x86-64 based.
Disk Space: 1.64 GB (does not include disk space for IDE/tools).
Tools: Flutter depends on these tools being available in your environment.
- Windows PowerShell 5.0 or newer (this is pre-installed with Windows 10)
- Git for Windows 2.x, 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

Download the following installation bundle to get the latest
stable release of the Flutter SDK:
(loading…)
For other release channels, and older builds,
check out the SDK archive.
Extract the zip file and place the contained flutter
in the desired installation location for the Flutter SDK
(for example, C:\src\flutter).

Warning:
Do not install Flutter to a path that contains special
characters or spaces.

Warning:
Do not install Flutter in a directory like
C:\Program Files\ that requires elevated privileges.

You are now ready to run Flutter commands in the Flutter Console.

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, enter ‘env’
and select Edit environment variables for your account.
Under User variables check if there is an entry called Path:
- If the entry exists, append the full path to flutter\bin using
  ; as a separator from existing values.
- If the entry doesn’t exist,
  create a new user variable named Path with
  the full path to flutter\bin as its value.

You have to close and reopen any existing console windows
for these changes to take effect.

Note:
As of Flutter’s 1.19.0 dev release, the Flutter SDK
contains the dart command alongside the flutter
command so that you can more easily run Dart
command-line programs. Downloading the Flutter SDK
also downloads the compatible version of Dart,
but if you’ve downloaded the Dart SDK separately,
make sure that the Flutter version of dart is
first in your path, as the two versions might not be compatible.
The following command tells you whether the flutter and dart
commands originate from the same bin directory and are
therefore compatible.

  C:\>
where flutter dart  C:\path-to-flutter-sdk\bin\flutter  C:\path-to-flutter-sdk\bin\flutter.bat  C:\path-to-dart-sdk\bin\dart.exe        :: this should go after `C:\path-to-flutter-sdk\bin\` commands  C:\path-to-flutter-sdk\bin\dart  C:\path-to-flutter-sdk\bin\dart.bat

As shown above, the command dart from the Flutter SDK doesn’t come first.
Update your path to use commands from C:\path-to-flutter-sdk\bin\ before
commands from C:\path-to-dart-sdk\bin\ (in this case).
After restarting your shell for the change to take effect,
running the where command again
should show that the flutter and dart commands
from the same directory now come first.

  C:\>
where flutter dart  C:\dev\src\flutter\bin\flutter  C:\dev\src\flutter\bin\flutter.bat  C:\dev\src\flutter\bin\dart  C:\dev\src\flutter\bin\dart.bat  C:\dev\src\dart-sdk\bin\dart.exe

However, if you are using PowerShell, in it where is
an alias of Where-Object command, so you need to use where.exe instead.

  PS C:\>
 
where.exe flutter dart

To learn more about the dart command, run dart -h
from the command line, or see the dart tool page.

Run `flutter doctor`

From a console window that 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:

C
:\src\flutter>flutter doctor

This command checks your environment and displays a report of the status
of your Flutter installation. Check the output carefully for other
software you might 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://docs.flutter.dev/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, you can run the flutter doctor command again to
verify that you’ve set everything up correctly.

Note:
If flutter doctor returns that either the Flutter plugin
or Dart plugin of Android Studio are not installed, move
on to Set up an editor to resolve this issue.

Warning:
The Flutter tool may occasionally download resources from Google servers.
By downloading or using the Flutter SDK you agree to the Google Terms of Service.

For example, when installed from GitHub (as opposed to from a prepackaged archive),
the Flutter tool will download the Dart SDK from Google servers immediately when
first run, as it is used to execute the flutter tool itself. This will also
occur when Flutter is upgraded (e.g. by running the flutter upgrade command).

The flutter tool uses Google Analytics to report feature usage
statistics and send crash reports. This data is used to help improve Flutter
tools over time.

Flutter tool analytics are not sent on the very first run. To disable
reporting, run flutter config --no-analytics. To display the current
setting, use flutter config. If you opt out of analytics, an opt-out
event is sent, and then no further information is sent by the
Flutter tool.

Dart tools may also send usage metrics and crash reports to Google.
To control the submission of these metrics, use the following options on the
dart tool:

--enable-analytics: Enables anonymous analytics.
--disable-analytics: Disables anonymous analytics.

The Google Privacy Policy describes how data is handled by these services.

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 discusses that.

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.
Run flutter doctor to 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 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_SDK_ROOT 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:

Enable
VM acceleration
on your machine.
Launch Android Studio, click the Device Manager
icon, and select Create Device under Virtual tab…
- 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
  3-Dot Menu / More Actions > Virtual Device Manager and select Create 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 11 installed and that your
JAVA_HOME environment 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
signing licenses.
```
$
 
flutter doctor --android-licenses
```
Review the terms of each license carefully before agreeing to them.
Once you are done agreeing with licenses, run flutter doctor again
to confirm that you are ready to use Flutter.

Windows setup

Additional Windows requirements

For Windows desktop development,
you need the following in addition to the Flutter SDK:

Visual Studio 2022 or Visual Studio Build Tools 2022
When installing Visual Studio or only the Build Tools,
you need the “Desktop development with C++” workload installed
for building windows, including all of its default components.

Note:
Visual Studio is different than Visual Studio Code.

For more information, see Building Windows apps.
