Answer: 
As you can see at the bottom right corner, you don't have an internet connection and thus, it can't reach `github.com`, which it seemingly needs to run.
**Step 1:** Download the Flutter SDK. We’ll have to download the Flutter SDK file in order to work with flutter. We can easily download it from the official website of Flutter.[click for preview](https://i.stack.imgur.com/Cqj1d.png)

**Step 2:** Set Environment variable path. After downloading Flutter SDK, extract the file and copy the path of the bin folder.

Now click on new and paste the path that was copied earlier and save.

Now We have to set up the Visual Studio Code for the Flutter. We have to install two extensions in order to use flutter. The very first extension is Flutter and 2nd is Dart. Note that Dart is the programming language that is used in flutter for the application development for both and android and iOS.

**Step 3:** Installing Flutter in Visual Studio Code

**Step 5:** Now we have successfully added Flutter and Dart to the Visual studio code, now let’s check if flutter is installed or not. For this we will open a new terminal in Visual Studio Code and type the following “flutter –version”, if everything is fine then it will normally show the version of the installed flutter.
