To install and run Flutter, your development environment must meet these minimum requirements:
- Operating Systems: Windows 7 SP1 or later (64-bit), x86-64 based
- Disk Space: 1.32 GB (does not include disk space for IDE/tools).
- Tools: Flutter depends on these tools being available in your environment.
Get the Flutter SDK
- 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 zip file and place the contained
flutterin the desired installation location for the Flutter SDK (for example,
C:\src\flutter or D:\app\android\flutter or any folder).
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, and change branches or tags as needed. For example:
C:\src>git clone https://github.com/flutter/flutter.git -b stable
You are now ready to run Flutter commands in the Flutter Console.
Update your path
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
;as a separator from existing values.
- If the entry doesn’t exist, create a new user variable named
Pathwith the full path to
flutter\binas its value.
- If the entry exists, append the full path to
You have to close and reopen any existing console windows for these changes to take effect.
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:
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).
[-] 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.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.
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.
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.
