Menu
To install the necessary Xcode tools using Xcode on the Mac: Start Xcode on the Mac. Choose Preferencesfrom the Xcode menu. In the General panel, click Downloads. The next option is to download the latest command line tools from Apple's developer page. To do this, you simply need to log into the downloads section of the Apple developer site using an Apple ID. Here you can search for 'Command Line Tools' to view all versions of the tools from Lion through Mavericks.
Reinstall Xcode Command Line Tools
System requirements
To install and run Flutter,your development environment must meet these minimum requirements:
Get the Flutter SDK
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
-v flag):
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 doctor command again to verify that you’ve set everything up correctly.
Warning: 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.
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.
By downloading the Flutter SDK, you agree to the Google Terms of Service. Note: The Google Privacy Policy describes how data is handled in this service.
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:
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 flutter and dart commands originate from the same bin directory and are therefore compatible. (Some versions of Windows support a similar where command.)
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 which or where command again should show that the flutter and 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.
Platform setup
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.
iOS setup![]() Install Xcode
To develop Flutter apps for iOS, you need a Mac with Xcode installed.
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:
Download Command Line Tools Mac
Create and run a simple Flutter app
To create your first Flutter app and test your setup,follow these steps:
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.
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
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.
![]() Set up the Android emulator
To prepare to run and test your Flutter app on the Android emulator,follow these steps:
Web setup
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.
Next step
Set up your preferred editor.
With an all-new design that looks great on macOS Big Sur, Xcode 12 has customizable font sizes for the navigator, streamlined code completion, and new document tabs. Xcode 12 builds Universal apps by default to support Mac with Apple Silicon, often without changing a single line of code.
Designed for macOS Big Sur.
Xcode 12 looks great on macOS Big Sur, with a navigator sidebar that goes to the top of the window and clear new toolbar buttons. The navigator defaults to a larger font that’s easier to read, while giving you multiple size choices. New document tabs make it easy to create a working set of files within your workspace.
Document tabs.
The new tab model lets you open a new tab with a double-click, or track the selected file as you click around the navigator. You can re-arrange the document tabs to create a working set of files for your current task, and configure how content is shown within each tab. The navigator tracks the open files within your tabs using strong selection.
Navigator font sizes.
The navigator now tracks the system setting for “Sidebar icon size” used in Finder and Mail. You can also choose a unique font size just for Xcode within Preferences, including the traditional dense information presentation, and up to large fonts and icon targets.
Code completion streamlined.
A new completion UI presents only the information you need, taking up less screen space as you type. And completions are presented much faster, so you can keep coding at maximum speed.
Redesigned organizer.
An all-new design groups all critical information about each of your apps together in one place. Choose any app from any of your teams, then quickly navigate to inspect crash logs, energy reports, and performance metrics, such as battery consumption and launch time of your apps when used by customers.
SwiftUI
SwiftUI offers new features, improved performance, and the power to do even more, all while maintaining a stable API that makes it easy to bring your existing SwiftUI code forward into Xcode 12. A brand new life cycle management API for apps built with SwiftUI lets you write your entire app in SwiftUI and share even more code across all Apple platforms. And a new widget platform built on SwiftUI lets you build widgets that work great on iPad, iPhone, and Mac. Your SwiftUI views can now be shared with other developers, and appear as first-class controls in the Xcode library. And your existing SwiftUI code continues to work, while providing faster performance, better diagnostics, and access to new controls.
Universal app ready.
Xcode 12 is built as a Universal app that runs 100% natively on Intel-based CPUs and Apple Silicon for great performance and a snappy interface.* It also includes a unified macOS SDK that includes all the frameworks, compilers, debuggers, and other tools you need to build apps that run natively on Apple Silicon and the Intel x86_64 CPU.
Updated automatically
When you open your project in Xcode 12, your app is automatically updated to produce release builds and archives as Universal apps. When you build your app, Xcode produces one binary “slice” for Apple Silicon and one for the Intel x86_64 CPU, then wraps them together as a single app bundle to share or submit to the Mac App Store. You can test this at any time by selecting “Any Mac” as the target in the toolbar.
Test multiple architectures.
On the new Mac with Apple Silicon, you can run and debug apps running on either the native architecture or on Intel virtualization by selecting “My Mac (Rosetta)” in the toolbar.
Multiplatform template
New multiplatform app templates set up new projects to easily share code among iOS, iPadOS, and macOS using SwiftUI and the new lifecycle APIs. The project structure encourages sharing code across all platforms, while creating special custom experiences for each platform where it makes sense for your app.
Improved auto-indentation
Swift code is auto-formatted as you type to make common Swift code patterns look much better, including special support for the “guard” command.
StoreKit testingXcode Command Line
New tools in Xcode let you create StoreKit files that describe the various subscription and in-app purchase products your app can offer, and create test scenarios to make sure everything works great for your customers — all locally testable on your Mac.
Get started.Install Xcode Command Line Tools
Download Xcode 12 and use these resources to build apps for all Apple platforms.
