Dart is a client-optimized programming language that supports various areas like multi-platform application development, formatting, analyzing, and testing code. It is a programming language that forms the basic foundation of Flutter. 

 Flutter is an open-source UI – Software development kit that helps develop applications for Android, iOS, Linux, Mac, Windows, Google Fuchsia, and the web in a single code base.

Visual Studio Code is a code editor developed by Microsoft for Windows, Mac, and Linux with features like code debugging, syntax highlighting, code completion, code refactoring, etc.

Dart SDK


Follow the below steps to install the dart SDK:

Step 1: Open Get the Dart SDK website.

Step 2: Scroll down to the bottom of the website and clickDownloading the SDK as a zip file.

Step 3: Based on your device’s architecture, Click the “Dark SDK” for Windows or Mac or Linux, accordingly.

Step 4: Once the download is complete, go to the “Downloads” folder and unzip the newly downloaded Dart-SDK zip file.

Step 5: For unzipping the file, right-click on the file and click “Extract Here”.

Step 6: Now, a new “dart-sdk” folder will be created in the “Downloads” folder.

Step 7: Copy this file and paste it in the “Program Files” folder in the “C” drive.

Step 8: Open “dart-sdk” folder and you will find a folder named “bin”.

Step 9: Now, right-click on the “bin” folder and choose “Properties”.

Step 10: In the “bin Properties” window, go to “Security” and copy the “Object Name”, also known as the address of the file, and press “Ok”.

Installation of Dart SDK


Step 11: Open “This PC” folder, right-click inside this folder, and choose “Properties”.  

Step 12: In the “System” window, select “Advanced system settings” that will be available on the left-hand side of the window.  

Step 13: In the “Advanced” tab, press the “Environment Variables…” button.

Step 14: In the “Environment Variables” window, under “User Variables for…” check for the “Path” variable.

Step 15: If it’s available, then press the “Edit” button, press “New” button in the “Edit environment variable” window, add the copied address to it and save the made changes.

Step 16: If it’s unavailable, then create one by pressing the “New” button and entering the “Variable Name” as “Path” and “Variable Value” as the copied address, and press “Ok”.

Step 19: If your output is just like above then, it signifies that dart has been installed successfully.

Visual Studio Code


Follow the below steps to set up dart in VS Code:

Step 1: Open Visual Studio Code in your device. 

Note: If unavailable then, open Download Visual Studio Code and download
       the application based on your device’s architecture and configurations.

Step 2: Press “Ctrl + B” and select “Extensions” or directly Press “Ctrl + Shift + X”.

Step 3: In the search bar, type “dart” and open the first extension named “Dart” by “Dart Code” in the list. Press the “Install” button.

Installing Dart in Visual Studio Code

Step 4: Once the installation is complete, click “File” and “New File”.

Step 5: Again click “File”, “Save As” and name the file with a “.dart” extension like “gfg.dart”. This file should be saved under a folder, but not as a loose file. So, if needed to create a new folder named “Dart” and save this new file under this folder.

Now, let’s code our first Dart program.


void main() {
  print("Welcome to GeeksforGeeks!");


Step 6: The above code helps us print the string “Welcome to GeeksforGeeks!”. Type or copy the above code in the coding area.

Step 7: Save the file by pressing “Ctrl + S” or by selecting “File” and “Save”.

Step 8: Now for running the code, press “Ctrl + Shift + D” and press “Run and Debug” button or open “Run” and select “Start Debugging”.

Step 9: Now a new file named “launch.json” will be created and it opens automatically in VS Code.


    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit:
    "version": "0.2.0",
    "configurations": [
            "name": "Dart & Flutter",
            "request": "launch",
            "type": "dart",
            "program" : "gfg.dart"


Step 10: In “launch.json” file, add “program value” inside the curly brackets ({}), like for example {“program” : “gfg.dart”} as shown above and save the file.

Note: If needed add a “,” (comma), to the previous value of "program" in the code of “launch.json” file.

Step 11: Now, press “Run” and then click “Run without Debugging”. The output of the dart file will be displayed in the “Debug Console”.


Welcome to GeeksforGeeks!


Step 12: Now for running the code in a terminal, press “Terminal” and click “New terminal”.

Step 13: Now in the terminal, type “dart file_name” like “dart gfg.dart” and press “Enter”.

Step 14: The output of the file will get displayed in the terminal.


PS C:\Users\name\Dart> dart gfg.dart
Welcome to GeeksforGeeks!
