Basic Installation

Important:

Choose your Platform and follow steps to build and run application.

How to Setup Flutter in Android Studio – Windows​

Step 1 : Get the Flutter SDK

1 Download the following installation bundle to get the latest stable release of the Flutter SDK:
2 Extract the zip file and place the contained flutter in the desired installation location for the Flutter SDK (for example, C:\src\flutter; do not install Flutter in a directory like C:\Program Files\ that requires elevated privileges).

Step 2 : Update your path

If you wish to run Flutter commands in the regular Windows console, take these steps to add Flutter to the PATH environment variable:
From the Start search bar, enter ‘env’ and select Edit environment variables for your account.
Under User variables check if there is an entry called Path:

  • If the entry exists, appendthe full path to flutter\bin using ; as a separator from existing values.
  • If the entry doesn’t exist, create a new user variable named Path with the full path to flutter\bin as its value.

Important:

Note that you have to close and reopen any existing console windows for these changes to take effect.

You are now ready to run Flutter commands in the Flutter Console!

Step 3 : Run flutter doctor

From a console window that has the Flutter directory in the path (see above), run the following command to see if there are any platform dependencies you need to complete the setup:

C:\src\flutter>flutter doctor

How to Setup Flutter in Android Studio – macOS​

Step 1 : Get the Flutter SDK

1 Download the following installation bundle to get the latest stable release of the Flutter SDK:
2 Download SDK and extract downloaded file, just double click on that. and just copy extracted folder and paste it to your desired location (for example, Documents\flutter).

Step 2 : Update your path

Important:

Path variable needs to be updated to access “flutter” command from terminal. you can just update path variable for current terminal window only. and if you want to access flutter commands from anywhere in terminal, we need to update SDK path permanently.

To update PATH variable, we need to open terminal.

To update PATH variable for current terminal window only, then enter this command “export PATH=”$PATH:`pwd`/flutter/bin”” and hit enter key.

To update PATH variable permanently, then Open or create .bash_profile file. to open or create that file, then enter “sudo open -e $HOME/.bash_profile” and hit enter key.

Append below line to bash_profile file at bottom of all other content. “export PATH=”$PATH:[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin”” as [PATH_TO_FLUTTER_GIT_DIRECTORY] is actual path of SDK folder.

Run this command on terminal “source $HOME/.bash_profile” to refresh PATH variables.

Then check whether our SDK is successfully installed or not.

You are now ready to run Flutter commands in the Flutter Console!

Run “flutter doctor” into terminal, If you are getting check list of flutter sdk requirements, it means SDK is successfully installed on your machine. and you can start building flutter apps on your machine.

Important:

Path variable needs to be updated to access “flutter” command from terminal. you can just update path variable for current terminal window only. and if you want to access flutter commands from anywhere in terminal, we need to update SDK path permanently.

You’ll probably want to update this variable permanently, so you can run flutter commands in any terminal session. To update PATH variable, we need to open terminal.

export PATH="$PATH:[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin"
  1. Run source $HOME/. to refresh the current window, or open a new terminal window to automatically source the file.
  2. Verify that the flutter/bin directory is now in your PATH by running:
echo $PATH

Verify that the flutter command is available by running:

which flutter

You are now ready to run Flutter commands in the Flutter Console!
