log meal: separate confirmation page with portion choice

[rolandgeider]

Would a slider be better here? Then it's easier to change the portion size (and it's clearer that we're talking about percentages)

[rolandgeider]

We could also make the slider move in 10% (or perhaps even 25%?) increments

[Dieterbe]

I was thinking something similar. But then I realized I want to be able to enter, say 150% or 200% for those times I need extra kcals. And any such UI would impose an upper limit

[rolandgeider]

I mean, the slider can also go to 200, with the default being 100 (and you can just log twice, if you need once a bigger amount)

[Dieterbe]

logging twice feels like an "unclean" solution, with possible ramifications. but i agree that if we make the need for this uncommon enough, it would be fine. e.g. allowing a portion size upto 150 or 200% maybe.
i was actually thinking a pie chart could be cool too, it could literally be a visual reference that you could match, if you're actually eating a piece of pie or pizza. but that clearly doesn't go above 100%

so okay, i can look into slider widgets. the UI needs some tweaking anyway.
but i suggest to merge this as is, and i'll add some polish later

[rolandgeider]

alright

[Dieterbe]

at a quick glance, we don't currently use such a widget anywhere, so i'll find one on pub.dev, unless you have a tip?

[rolandgeider]

I think flutter itself has one

[rolandgeider]

yep https://api.flutter.dev/flutter/material/Slider-class.html
