hackernews-android VS BizCard1

this is repo in case anyone want to take a look at the code. I'm still very confused about livedata, coroutine.. things https://github.com/cuongtranduc/hackernews-android

5) I started with the (old / XML) Kotlin course, and was making slow but steady progress there, until I figured out I was supposed to be learning Compose instead, which is a different course maybe with some overlapping content? No idea. So that's where I went and am now. I probably would have preferred someone just tell me which one I should do first or only. I was moving thru the Compose course until I hit the Business Card exercise where it said, just do this, and no solution, because the only way to learn things is to do it by yourself -- tee-hee. OK. If I had a solution there at the end I would have looked at it after struggling a bit, implemented it, then moved on. But it's not there, which led me to the internet and that solution that I still don't understand (in my other comment). I finally figured out the Layout for the most part -- enough to keep it movin. Oddly, the Business Card problem, for however simple is seems to experts, is not actually simple to me -- it somewhat looks like the main 'AndroidIcon / Name / Title' part is roughly in the center of the screen -- but is it? How do I get that there? But since I know it's not directly in the middle, because then it wouldn't be balanced, it would be too low, how do I get it a bit above there maybe? But will it be pushed up by whatever is below it? And I'm going to use a Box for both sections of the screen because that's the obvious thing to do, but a Box is some kind of 'non-blocking' container, unlike a Row and a Column, so.... it means absolute, not relative, layouts? And what happens on different size screens? Will things shift up or down? Can I use percentages or abssolute .dps or I read something about a 'weight'? So, I think specifying the requirements on this layout in explicit detail would actually be very helpful, and short of that posting a simple solution would have saved me a lot of time, helped me learn faster, etc.
