Get the Flutter SDK
To get Flutter, use
git to clone the repository and then add the
flutter tool to your path. Running
flutter doctor shows any remaining dependencies you may need to install.
Clone the repo
If this is the first time you’re installing Flutter on your machine, clone the
beta branch of the repository and then add the
flutter tool to your path:
$ git clone -b beta https://github.com/flutter/flutter.git $ export PATH=`pwd`/flutter/bin:$PATH
The above command sets your PATH variable temporarily, for the current terminal window. To permanently add Flutter to your path, see Update your path.
To update an existing version of Flutter, see Upgrading Flutter.
Run flutter doctor
Run the following command to see if there are any dependencies left that you need to install to complete the setup:
$ flutter doctor
