System requirements

I can't seem to download Android Studio at all. I go to the official download page of AS, but nothing happens. I get no Pop-ups or nothing, and my internet connection is fine. Cannot install Android material on Mac Catalina fixed in: visual studio 2019 for mac version 8.4.3 visual studio for mac Tom Diaz reported Jan 12 at 11:28 PM.

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.
- bash
- curl
- git 2.x
- mkdir
- rm
- unzip
- which
- zip

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 archive 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:
Add the flutter tool to your path:
This command sets your PATH variable for thecurrent terminal window only.To permanently add Flutter to your path, seeUpdate your path.
Optionally, pre-download development binaries:
The flutter tool 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 -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).

For example:

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.

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:

Determine the directory where you placed the Flutter SDK.You need this in Step 3.
Open (or create) the rc file for your shell.Typing echo $SHELL in your Terminal tells youwhich shell you’re using.If you’re using Bash,edit $HOME/.bash_profile or $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:
Run source $HOME/.<rc file>to refresh the current window,or open a new terminal window toautomatically source the file.
Verify that the flutter/bin directoryis now in your PATH by running:
Verify that the flutter command 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 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.

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 runningsudo xcodebuild -license from the command line.

Versions older than the latest stable version may still work,but are not recommend
