Firstly, try to set the environment variable path correctly, like install it in %userprofile%/flut(🪟 + r)

) folder and set the path, in systems environment variable. And then, restart the computer and check the flutter version in cmd or any other command line tools for checking the versions and installation is done or not

using command flutter --version and for dart installation do the same process, and check the version using dart --version using cmd or any other tool.

Then, try to run flutter doctor, to check any other misconfigurations.

Then, check for flutter doctor --licenses for futher configurations left with and check the SDK manager for remaining requirements as per the project you are building.

Try, upgrading with command flutter pub get to check the versions compatibillities and flutter pub upgrade to get the missing requirements.

Now, try to run flutter run filepath where you had your file for the application.

I hope, this will give your desired results and if not, you can connect and ask you questions, here only.
