[#541] Integrate the Twitter Jetpack Compose Rules Detekt plugin #556

ryan-conway · 2023-11-03T08:01:18Z

closes #541

What happened 👀

Added the compose-rules detekt plugin
Updated detekt-config.yml
Added kotlinx.collections.immutable dependency and updated UI lists to use ImmutableList
Brought detekt rules changes to sample-compose

Insight 📝

As the Twitter compose-rules detekt plugin seems abandoned, we should instead use a forked version from one of the original maintainers which is being actively worked on 🙏🏻
Because compose treats all instances of Collection (i.e., List, Set, etc.) as unstable, we should update all UI usages of collections to use their ImmutableX counterpart to reduce unnecessary recomposition.
- Reference: https://medium.com/androiddevelopers/jetpack-compose-stability-explained-79c10db270c8
We have added ignoreAnnotated: [ 'Preview' ] to the MagicNumber rule as preview composables typically contain hard-coded values and we don't want these to be flagged 👀

Proof Of Work 📹

With incorrect composable name (homeScreenContent), public @Preview and unstable lists:

/Users/ryanconway/Projects/Nimble/android-templates/template-compose/app/src/main/java/co/nimblehq/template/compose/ui/screens/home/HomeScreen.kt:41:13: Composable functions that return Unit should start with an uppercase letter.
They are considered declarative entities that can be either present or absent in a composition and therefore follow the naming rules for classes.

/Users/ryanconway/Projects/Nimble/android-templates/template-compose/app/src/main/java/co/nimblehq/template/compose/ui/screens/home/HomeScreen.kt:43:15: The Compose Compiler cannot infer the stability of a parameter if a List<UiModel> is used in it, even if the item type is stable.
You should use Kotlinx Immutable Collections instead: `uiModels: ImmutableList<UiModel>` or create an `@Immutable` wrapper for this class: `@Immutable data class UiModelsList(val items: List<UiModel>)`

IMO, the unstable list should be handled in another PR instead. This PR is about to update the Jetpack Compose Rule. 🤔 Please correct me if I'm wrong. 🙇🏻

@lydiasama That's a fair point, but since these are new rules introduced in this task it made sense to me to handle them here as well instead of opening another task, what do you think? 🤔

    viewModel: SecondViewModel = hiltViewModel(),
    navigator: (destination: BaseDestination) -> Unit,


Should the viewModel param with the default value be located at the end as well?

Suggested change

viewModel: SecondViewModel = hiltViewModel(),

navigator: (destination: BaseDestination) -> Unit,

navigator: (destination: BaseDestination) -> Unit,

viewModel: SecondViewModel = hiltViewModel(),

    id: String,

    onUpdateClick: () -> Unit,


Please cross-check with some config from https://github.com/appKODE/detekt-rules-compose, which forces us to order the Modifier with the default value at the end. I think that's a good convention to apply as well 🤔
