Our coding standards enforces a space after the closing method parentheses and the proceeding colon.
It would super advantageous if this space could be configurable and honored in the printReturnType method.

Currently we have to manually go to all generated files and apply the spacing. As you can imagine this is very monotonous. I'm sure many others could also benefit from this.

I would super happy to contribute a PR if this is taken into consideration.
