Proceed with board specific instructions. When the Arduino Software (IDE) is properly installed you can go back to the Getting Started Home and choose your board from the list on the right of the page. Use a Mac OS X installation Disc. If you’re unable to use Internet Recovery Mode or create a bootable USB installer, you can still use a Mac OS X installation disc. These discs are available for OS X Snow Leopard, OS X Lion, and OS X Mountain Lion. If your Mac is from 2012 or earlier, there was an installation disc in the original box.
- Get the Flutter SDK
- iOS setup
- Android setup
To install and run Flutter,your development environment must meet these minimum requirements:
- Operating Systems: macOS (64-bit)
- Disk Space: 2.8 GB (does not include disk space for IDE/tools).
- Tools: Flutter depends on these command-line tools being availablein your environment.
Get the Flutter SDK
Download the following installation bundle to get the lateststable 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:
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 repoon GitHub with the following command:
You can also change branches or tags as needed.For example, to get just the stable version:
fluttertool to your path:
This command sets your
PATHvariable for thecurrent terminal window only.To permanently add Flutter to your path, seeUpdate your path.
Optionally, pre-download development binaries:
fluttertool downloads platform-specific development binaries asneeded. For scenarios where pre-downloading these artifacts is preferable(for example, in hermetic build environments,or with intermittent network availability), iOSand Android binaries can be downloaded ahead of time by running:
For additional download options, see
flutter help precache.
You are now ready to run Flutter commands!
Note: 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 toinstall to complete the setup (for verbose output, add the
This command checks your environment and displays a report to the terminalwindow. The Dart SDK is bundled with Flutter; it is not necessary to installDart separately. Check the output carefully for other software you mightneed to install or further tasks to perform (shown in bold text).
The following sections describe how to perform these tasks and finish the setupprocess.
Once you have installed any missing dependencies, run the
flutter doctorcommand again to verify that you’ve set everything up correctly.
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.
Flutter tool analytics are not sent on the very first run. To disable reporting, type
flutter config --no-analytics. To display the current setting, type
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.

Moreover, Flutter includes the Dart SDK, which may send usage metrics and crash reports to Google.
Update your path
You can update your PATH variable for the current session atthe 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 forall terminal sessions are machine-specific.Typically you add a line to a file that is executedwhenever you open a new window. For example:
- Determine the directory where you placed the Flutter SDK.You need this in Step 3.
- Open (or create) the
rcfile for your shell.Typing
echo $SHELLin your Terminal tells youwhich shell you’re using.If you’re using Bash,edit
$HOME/.bashrc.If you’re using Z shell, edit
$HOME/.zshrc.If you’re using a different shell, the file pathand filename will be different on your machine.
Add the following line and change
[PATH_TO_FLUTTER_GIT_DIRECTORY]to bethe path where you cloned Flutter’s git repo:
source $HOME/.<rc file>to refresh the current window,or open a new terminal window toautomatically source the file.
Verify that the
flutter/bindirectoryis now in your PATH by running:
Verify that the
fluttercommand is available by running:
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 (on macOS, linux, and chrome OS), tells you whether the
dart commands originate from the same
bin directory and are therefore compatible. (Some versions of Windows support a similar
As shown above, the two commands don’t come from the same
bin directory. Update your path to use commands from
/path-to-flutter-sdk/bin before commands from
/usr/local/bin (in this case). After updating your shell for the change to take effect, running the
where command again should show that the
dart commands now come from the same directory.
To learn more about the
dart command, run
dart -h from the command line, or see the dart tool page.
macOS supports developing Flutter apps in iOS, Android,and the web (technical preview release).Complete at least one of the platform setup steps now,to be able to build and run your first Flutter app.
To develop Flutter apps for iOS, you need a Mac with Xcode installed.
- Install the latest stable version of Xcode(using web download or the Mac App Store).
Configure the Xcode command-line tools to use thenewly-installed version of Xcode byrunning the following from 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 byeither opening Xcode once and confirming or running
sudo xcodebuild -licensefrom the command line.
Versions older than the latest stable version may still work,but are not recommended for Flutter development.Using old versions of Xcode to target bitcode is notsupported, and is likely not to work.
With Xcode, you’ll be able to run Flutter apps onan 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 orby using the following command:
- Make sure your simulator is using a 64-bit device(iPhone 5s or later) by checking the settings inthe simulator’s Hardware > Device menu.
- Depending on your development machine’s screen size,simulated high-screen-density iOS devicesmight overflow your screen. Grab the corner of thesimulator and drag it to change the scale. You can alsouse the Window > Physical Size or Window > Pixel Accurateoptions if your computer’s resolution is high enough.
- If you are using a version of Xcode olderthan 9.1, you should instead set the device scalein the Window > Scale menu.
Create and run a simple Flutter app
To create your first Flutter app and test your setup,follow these steps:
Create a new Flutter app by running the following from thecommand line:
my_appdirectory is created, containing Flutter’s starter app.Enter this directory:
To launch the app in the Simulator,ensure that the Simulator is running and enter:
Installation Code For Macbook Pro
Deploy to iOS devices
To deploy your Flutter app to a physical iOS deviceyou’ll need to set up physical device deployment in Xcodeand an Apple Developer account. If your app is using Flutter plugins,you will also need the third-party CocoaPods dependency manager.
You can skip this step if your apps do not depend onFlutter plugins with native iOS code.Install and set up CocoaPods by running the following commands:
Note: The default version of Ruby requires
sudoto install the CocoaPods gem. If you are using a Ruby Version manager, you may need to run without
Follow the Xcode signing flow to provision your project:
- Open the default Xcode workspace in your project byrunning
open ios/Runner.xcworkspacein a terminalwindow from your Flutter project directory.
- Select the device you intend to deploy to in the devicedrop-down menu next to the run button.
- Select the
Runnerproject in the left navigation panel.
- In the
Runnertarget settings page,make sure your Development Team is selected.The UI varies depending on your version of Xcode.
- For Xcode 10, look under General > Signing > Team.
- For Xcode 11 and newer, look underSigning & Capabilities > Team.
When you select a team,Xcode creates and downloads a Development Certificate,registers your device with your account,and creates and downloads a provisioning profile (if needed).
- To start your first iOS development project,you might need to sign intoXcode with your Apple ID. Development and testing is supported for any Apple ID.Enrolling in the Apple Developer Program is required todistribute your app to the App Store.For details about membership types,see Choosing a Membership.
The first time you use an attached physical device for iOSdevelopment, you need to trust both your Mac and theDevelopment Certificate on that device.Select
Trustin the dialog prompt whenfirst connecting the iOS device to your Mac.
Then, go to the Settings app on the iOS device,select General > Device Managementand trust your Certificate.For first time users, you may need to selectGeneral > Profiles > Device Management instead.
If automatic signing fails in Xcode, verify that the project’sGeneral > Identity > Bundle Identifier value is unique.
- Open the default Xcode workspace in your project byrunning
Start your app by running
flutter runor clicking the Run button in Xcode.
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 Flutterwhen 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 theAndroid documentation.
- Windows-only: Install the Google USBDriver.
- Using a USB cable, plug your phone into your computer. If prompted on yourdevice, authorize your computer to access your device.
- In the terminal, run the
flutter devicescommand to verify thatFlutter 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 installationof the Android SDK, you must set the
ANDROID_SDK_ROOTenvironmentvariable 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:
- EnableVM accelerationon your machine.
- Launch Android Studio, click the AVD Managericon, and select Create Virtual Device…
- In older versions of Android Studio, you should insteadlaunch Android Studio > Tools > Android > AVD Manager and selectCreate Virtual Device…. (The Android submenu is only presentwhen 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 wantto emulate, and select Next.An x86 or x86_64 image is recommended.
- Under Emulated Performance, select Hardware - GLES 2.0 to enablehardwareacceleration.
Verify the AVD configuration is correct, and select Finish.
For details on the above steps, see ManagingAVDs.
- In Android Virtual Device Manager, click Run in the toolbar.The emulator starts up and displays the default canvas for yourselected OS version and device.
Flutter has early support for building web applications using the
beta channel of Flutter. To add support for web development, followthese instructions when you’ve completed the setup above.
Set up your preferred editor.
These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.
Find the appropriate download link in the upgrade instructions for each macOS version:
macOS Catalina, macOS Mojave, ormacOS High Sierra
Installers for each of these macOS versions download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation. Important: To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
OS X El Capitan
El Capitan downloads as a disk image. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.
Use the 'createinstallmedia' command in Terminal
- Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
- Open Terminal, which is in the Utilities folder of your Applications folder.
- Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace
MyVolumein these commands with the name of your volume.
- Press Return after typing the command.
- When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
- When prompted, type
Yto confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.
- When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.
* If your Mac is using macOS Sierra or earlier, include the
--applicationpath argument, similar to the way this argument is used in the command for El Capitan.
Use the bootable installer
After creating the bootable installer, follow these steps to use it:
- Plug the bootable installer into a compatible Mac.
- Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it.
- Choose your language, if prompted.
- A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
- Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.
