There are three major OS and I am pretty sure you also use one of them.
Flutter docs cover everything about the installation in very easy way.
If you face any issue while installation you can Google because lots of people are trying flutter everyday.
There is very much possibility that the problem you are facing is faced by lots of other developer too.
