Extension Function For Kotlin Data Class

I have a data class which looks something like this data class SuggestionResponse( val metadata: Metadata, val response: Response ) data class Response( ///blah blah ) data

Solution 1:

Just create an extension function on SuggestionResponse class and you'll have access to the properties of SuggestionResponse class:

fun SuggestionResponse.hello() { 
    //`metadata` property is available here//`response` property is available hereval time = metadata.timeleft
}

And then you'll be able to call it on an instance of SuggestionResponse class:

suggestionResponse.hello()
