Gosublime indent not working (might be there is an issue with gofmt in gosublime)

Question

I have pasted two images here

Here you can see proper indentation in Gedit text editor

Now, in Sublime3 it is not proper

I'm using GoSublime and my settings are:

{
    "env": {
        "GOROOT": "/usr/local/go",
        "GOPATH":"$HOME/go-work"
    }
}

How to ident go code properly in sublime text editor?
