After a long discussion with this lib author, it seems can set the padding value to ImplicitlyAnimatedList.
My proposal is can you consider expose this params out so that users can choose to set it or not? thanks.

Sure I can. But have you tested it?

[lucasjinreal]

@themadmrj I haven't Sir. Can u indicates me where put the params is OK, let me test it on my side first since only my APP have this weired usage.

You don't need a change in the library. Just change the code in your cache to test it. If it solves your problem, I'll make the change in the lib.

[lucasjinreal]

@themadmrj Don't understand. I mean which class I need change to the chatui.... regardless of change lib or cache on my local...

I'm just saying I'm waiting for you to test the solution to check whether it works, before I change the library... From what I could read in your discussion in the other library, you discussed it, but nobody tested it even once!
