I am learning sunflower app and came across this tabFragmentsCreators variable https://github.com/android/sunflower/blob/master/app/src/main/java/com/google/samples/apps/sunflower/adapters/SunflowerPagerAdapter.kt#L32
What is the benefit of using a Map<Int, () -> Fragment> instead of just Map<Int, Fragment>

[Araib]

Lazy creating fragment instance instead of keeping fragment instance in map (that's my understanding of it..)

[Chung]

Thanks, so it is just creating the fragments when it is "asked"(on-demand)?

[Araib]

Yeah

() -> fragment

Will provide fragment when required

[Araib]

So instead of keeping instance of fragment mapped to int, we keep a function which gives an instance of fragment and map that to int

[Chung]

That makes sense. Thanks for your explanation👍

[Daniel]

nice
