Hey guys, how can I call a function extension that is declared in another class?

jackmiras: the best way is to just make the function top-level

I've done this but I'm having some problems in call the function.
Even if I specify the package of the class that holds the extended function the IDE doesn't find the function.

I have this class that has a extension function:
Copy code
class RequestExtentions {

    fun Request.bodyObject(): Any {
        try {
            return Parser().toKotlin(body())
        } catch (e: Exception) {
            return e
        }
    }

}
I would like to call the function above in another class just like the code down below:
Copy code
override fun post(req: Request, res: Response): Any {
        val platform = req.bodyObject()
    }
The problem is that when I try to do this val platform = req.bodyObject() I can't import the bodyObject function

i'm not sure this is possible. why not put the extension method outside of the class?
or put the extension method next to your 
fun post(..)

The extension function was next to the 
fun post(...)
but this function will repeat along other classes.
That's why I would like to move the function to the 
class RequestExtentions {...}
@Andreas Sinz do you know if there is a way to make this work?

@jackmiras nope, I don't know any way to do it. just make your extension function a top-level function
