is there a way of using

with

when the variable é optional? for instance, inside a fragment, the

activity

is optional, so can I use something like

private fun goToMain() = with(activity) {
            val intent = Intent(this, MainActivity::class.java)
            startActivity(intent)
            finishAffinity()
}

You can replace it with

activity?.run { }

Right, it was discussed before, basically

.run{}

is the equivalent of

with

plus nullable support, so one might think that the usage of

with

is a bit questionable.

@ghedeon i guess

with

is more readable

I'm inclined to agree with you. I went through the same process: was using

with

then realised this limitation, then didn't want to mix both for basically the same thing and refactor every time I switch null/nullable... Ended up using

.run

almost everywhere.

An alternative is creating your own function, such as

withOptional

or something
