Hi@akhtar,
You can follow the below-given steps to install Flutter in your system.
https://storage.googleapis.com/flutter_infra/releases/stable/windows/flutter_windows_1.17.5-stable.zip
- 
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).
 
- 
If you wish to run Flutter commands in the regular Windows console, then you need to add the path in your system environment.
 
- 
To check flutter is installed or not. Run the below command in your command prompt.
