how do you write error statement

In go, when I write an error statement, I don’t keep any space between function call and error check statement, such as -

something, err := doSoemthing()
if err != nil {
	//handle error
}

But I have also seen people doing following -

something, err := doSoemthing()

if err != nil {
	//handle error
}

How do you write that error check?
