There s no way to peek into a function and see what other functions it calls but depending on what you re actually trying to do there are probably other ways to approach the problem

I ve been trying and failing to recreate this airbnb like carousel using accompanist horizontalPager Which has led me down a rabbit hole to ask the above question rolling on the floor laughing

Colton Idle · Answer

It seems like horizontalPager only lets you have 1 item on the screen plus 1 that s peeking in

Colton Idle · Answer

But trying to get multiple items via setting a width on the item composable of like 100 dp just doesn t work HorizontalPager just keeps adding a huge gap between items thinking face Can t tell if I m an idiot or maybe it s not a use case of HP or if its an HP bug

< Colton Idle> Unless I m missing something you can just use a scrollable Row or a LazyRow for this

Casey Brooks · Answer

`Modifier swipeable` might be the thing you need Put the items in a horizontal row and make it swipeable to snap to each item in the row Or just a normal horizontally scrolling row if you don t need the snapping behavior <https developer android com jetpack compose gestures swiping>

Colton Idle · Answer

I need the pager dots at the bottom of this too which isn t shown in the airbnb example but yes you re right I could do it with a scrollable row

Colton Idle · Answer

So more accurately I want the airbnb carousel with dots here are the dots if anyone is unfamiliar

Colton Idle · Answer

also a nicer benefit too of horizontalPager that my UX team likes is that you get item snapping with horizontalPager vs just a scollable Row

Ian Lake · Answer

It sounds like you don t actually want a pager you just want the snap behavior Did you see Chris s recent work to separate the snap positioning into something you can apply to any list <https twitter com chrisbanes status 1442909344597635072|https twitter com chrisbanes status 1442909344597635072>
