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 into the “Program Files” folder in the “C” drive.

Step 8: Open the “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”.

Setup

Step 11: Open the “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 the “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 17: Now open the Command Prompt (cmd) and type "dart".

Step 18: The output will be as follows.

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

Visual Studio Code

Installation

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

Step 1: Open Visual Studio Code on 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.

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

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

Now, let’s code our first Dart program.

Dart

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 the “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.

Dart

{     // Use IntelliSense to learn about possible attributes.     // Hover to view descriptions of existing attributes.     // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387     "version": "0.2.0",     "configurations": [         {             "name": "Dart & Flutter",             "request": "launch",             "type": "dart",             "program" : "gfg.dart"         }     ] }

Step 10: In the “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".

Dart

Welcome to GeeksforGeeks! Exited

Step 12: Now to run the code in a terminal, press "Terminal" and click "New terminal".

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

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

Dart

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