This guide describes how to set up your development environment to run Flutter apps on iOS or Android.
- System requirements
- Get the Flutter SDK
- Google Analytics
- iOS setup
- Android setup
- Editor setup
- Next steps
To install and run Flutter, your development environment must meet these minimum requirements:
- Operating Systems: Mac or Linux (64-bit). Windows support is in progress.
- Tools: Flutter depends on these command-line tools being available on your environment.
Get the Flutter SDK
To get Flutter, use
git to clone the repository and then add the
flutter tool to your path:
$ git clone https://github.com/flutter/flutter.git $ export PATH=`pwd`/flutter/bin:$PATH
Run the following command to see if there are any dependencies you need to install to complete the setup:
$ flutter doctor
The first time you run the
flutter command, it will download its dependencies and compile
itself. Subsequent runs should be much faster.
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.
In order to disable reporting, type
flutter config --no-analytics, and to display the
current state of analytics reporting, type
Analytics is not sent on the very first run or for any runs involving
This lets users choose to opt-out of analytics without any data being sent. See Google’s
This step is optional, and can be performed at any time before using Flutter to develop apps for iOS.
To develop Flutter apps for iOS, you need a Mac with Xcode 7.2 or newer:
- Install Xcode 7.2 or newer (via web download or the Mac App Store).
- Configure the Xcode command-line tools to use the newly-installed version of Xcode by
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developerfrom the command line.
This is the correct path for most cases, when you want to use the latest version of Xcode. If you need to use a different version, specify that path instead.
- Make sure the Xcode license agreement is signed by either opening Xcode once and confirming or
sudo xcodebuild -licensefrom the command line.
With Xcode, you’ll be able to run Flutter apps on an iOS device or on the simulator.
Set up the iOS simulator
To prepare to run and test your Flutter app on the iOS simulator, follow these steps:
On your Mac, find the Simulator via Spotlight or by using the following command:
$ open -a Simulator
- Make sure your simulator is using a 64-bit device (iPhone 5s or later) by checking the settings in the simulator’s Hardware > Device menu.
- Depending on your development machine’s screen size, simulated high-screen-density iOS devices may overflow your screen. Set the device scale under the Window > Scale menu in the simulator.
Deploy to iOS devices
To deploy your Flutter app to a physical iOS device, you’ll need some additional tools:
- Install homebrew.
Open the terminal and run this command to install the tools for deploying Flutter apps to iOS devices.
$ brew install ideviceinstaller ios-deploy
You’ll also need to set up a provisioning profile for your developer account. To learn how to set up your profile, see Apple’s official documentation.
This step is optional, and can be performed at any time before using Flutter to develop apps for Android.
To develop Flutter apps for Android, you can use either a Mac or a Linux (64-bit) machine:
- Install Android Studio.
- From Android Studio, install the latest Android SDK and Android SDK Platform-Tools, as described in Adding SDK Packages.
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.
- Enable developer mode on your device by visiting
Settings > About phoneand tapping the
Build numberline seven times.
Settings > Developer options, enable
- 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
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 specific installation directory.
Using our command-line tools, you can use any editor to develop Flutter applications.
Now, follow our Getting Started guide to run your first Flutter app on iOS and Android.
