Let's say a composable is about to enter/added to the tree how can I animate it's enter transition ? Is there something similar to .transition modifier like swiftUI ?

AnimatedVisibility: https://developer.android.com/jetpack/compose/animation
The video on top of the page would help if you are not familiar with the content on that page. 🙂

@Doris Liu Is there any example of z index animation + Slide in/Slide out when transition from one screen to another like IOS have?

[Doris Liu]

@Shakil Karim screen level enter/exit animations are ongoing work. 😄 Though I'm very curious about the z index animation that you are referring to. Could you share a demo of that?

[Shakil Karim]

@Doris Liu Sorry, I meant parallax effect like in this video

File from iOS.MP4

[Doris Liu]

I see. The exiting screen slides out slower than the entering one. That should be doable if we support independent enter/exit transition for each screen. 🙂 Thanks for sharing! 🙏

[Shivam Sethi]

Thanks for these references😄

Okay, I tried animated visibility, it is not working. All I want it just animate enter transition on a composable?

[Doris Liu]

Can you share a code snippet?

[Doris Liu]

You'll probably need to do something like AnimatedVisibility(visible = true, initiallyVisible = false) to just show an enter transition. 🙂

[Shivam Sethi]

hmm, I am doing exactly this but this results in not showing anything to the screen

[Doris Liu]

Does the composable show up without being wrapped in AnimatedVisibility ?

[Shivam Sethi]

yes, but when I wrap it, then nothing shows up

[Shivam Sethi]

here is the code screenshot for that composable that I want to animate transition

[Doris Liu]

That looks correct. Is this AnimatedVisiblity happen to be nested in another AnimatedVisibility? Are you using emulator or studio preview?

[Shivam Sethi]

I am using physical android device, and no it is not nested in another AnimatedVisibility Its top level composable HomeScree just initializes a viewModel and pass the desired data down to this composable ?

[Doris Liu]

What version of compose are you using, beta01, beta02?

[Shivam Sethi]

just updated to beta02

[Doris Liu]

If you could isolate the issue in a minimal repro case, I'm happy to take a look. 🙂

[Shivam Sethi]

I probably will not be able to do that currently, but will try later on. thank you very much for answering by the way.

[Shivam Sethi]

would you recommend something like this for time being, as replacement for AnimatedVisibility for enter transition ?

[Doris Liu]

If that works for you, it's a valid option. 🙂

[Shivam Sethi]

Thanks, yes it works just thought If it would be valid to do like this.
