Nice video! But you did a mistake explaining with. You still referred to square when it should be this. But easy to miss these things :)

[dikshakoratkar]

This tutorial is very helpful. My all concepts cleared about scope function

[saquibsiddique]

please dive a little deep into how they are working and why we have 5 different scope functions

[silvahawk]

I think it'd be nice if you could explain the difference in this vs. it as well. I kinda understood the concept, but had to look it up myself for the difference between those keyword to make sure I didn't miss anything

[manyantra]

[kishorramani]

If we can't return this, it also work
In which situation, it's not updating value

Pl make some videos on covariance and contravariance in kotlin. I don't undestsnd the meaning of out keyword in kotlin. No youtuber from our country has yet made any video to clear this concept. It will be your great favour to me if you make video
on covariance and contravariance in kotlin

Hi run and with are almost same? Instead run is better because less code?

[thakurgopaldangi]

hello, video are good but still how we can use scope function differently? all are done same kind of task with its objects.

[TheKamble]

I still don't get the difference between them. They appear pretty similar to be, maybe adding some use cases would help. I only use let and apply. The rest I don't know where to use them.

Usage in android:

Intent(this, SignupActivity::class.java)
.apply{
putStringExtra(SCOPE_KEY, "admin")
}
.also{it ->
startActivity(it)
}
