Adds the `@DayNightPreviews` annotation that when used on a composable will:
- Display both a day mode and night mode preview in Android Studio.
- Produce both a day and night screenshot during screenshot testing.
The usage of this new annotation is optional, all the current previews continue to work without breakages.
New code can use, when appropriate, the new `@DayNightPreviews` annotation and replace the pattern using three `LightPreview/DarkPreview/ContentToPreview` functions with:
```
@DayNightPreviews
@Composable
fun MyScreenPreview(@PreviewParameter(MyStateProvider::class) state: MyState) {
ElementPreview {
MyScreen(
state = state,
)
}
}
```
With this change, composable previews and screenshots should be created with just:
```
@ElementPreviews
@Composable
fun MyViewPreview() {
ElementPreview {
MyView()
}
}
```
- Adds `@ElementPreviews` which is a shorthand for:
```
@Preview(name = "D")
@Preview(name = "N", uiMode = Configuration.UI_MODE_NIGHT_YES)
```
Should be used in connection with the now public `fun ElementPreview()` composable.
- Adds ElementPreviews to previewAnnotations in dangerfile
- Screenshots of night mode previews are now rendered with night mode
- Replaces `ElementPreviewLight` and `ElementThemedPreview` with `ElementPreview`
- Deprecates `ElementPreviewDark` which should be removed.
- Remaining usages of `ElementPreviewDark` are now ignored during screenshot tests
We have screenshot tests that basically negate the need for this,
and when we're doing more complicated things we tend to use
videos anyway which aren't caught by this check.
Now we have a CODEOWNERS file a reviewer is assigned automatically,
so there's no need for this.
It also misfires a bunch (maybe if there are no _pending_ reviewers
because they've already reviewed?), so removing it fixes that noise.
Make danger check view changes
Add a check that if a file with @Preview or @LargeHeightPreview
in it is changed, then the corresponding build file includes
the showkase processor.
Also change the check that prompts about screenshots to use
the same @Preview logic instead of checking for "/layout" in
the path which doesn't work with compose.
Also add missing showkase processors
