compose-samples VS sunflower

Apparently Jetpack Compose is an Android copy of SwiftUI?

Only two HN threads with comments: https://hn.algolia.com/?q=jetpack+compose

Basic understanding of Jetpack Compose.

The compose-samples repo has a comprehensive list of samples ranging from low to complex projects which might be worth a look.

And what was learned from Flutter has produced something I consider even more interesting: Compose UI (https://developer.android.com/jetpack/compose) and JetBrains' Compose Multiplatform (https://www.jetbrains.com/lp/compose-mpp/)

Now, same story, in the current documentation the list is replaced by a single UserMessage without any explanation of the previous example. It just says "For a more advanced use case, displaying a list of user messages on screen, check out the Jetsnack Compose example." .

As for the strange infix syntax, you're correct - it's not important (for Dart anyway). Kotlin supports writing code that have DSL like syntax making things like typesafe HTML or Jetpack Compose possible.

Sample apps

https://github.com/android/sunflower?

Technically the 2019 version of this repo https://github.com/android/sunflower/tree/5d5dd9e1f0bee1ef506d70aaacf21fe893a9fb83 was significantly less clear than newer versions.

Check out their example of the perfect app https://github.com/android/sunflower

Like looking at Google's android/sunflower app... I see it and it see how they are all divided viewmodel/fragment/workers but what should I be paying attention to when looking at sample apps to learn ?

After you are quite proficient with the framework, this time you should discover new things. The most trusted source is the samples from Google, for example, Sunflower

While not an app, accompanist has quite a good coverage for UI-related things. From a quick look, so does sunflower.

Google samples pretending that the right way to observe 11 LiveDatas that weren't even a minimal state representation required Databinding, and most people don't like Databinding due to its intrusive nature (which is a byproduct of kapt running for layout modifications + people completely misusing @BindingAdapters as if they were "XML extension functions" or something rather than use them for what they actually were for)
