Practical Tips and Tricks to Improve Your Compose Previews
summary
Explains concrete, usable techniques: use preview-annotation parameters like showBackground and backgroundColor and uiMode to get accurate light/dark previews, group previews with group/multi-preview constants, and build reusable annotation wrappers and a preview Box composable that applies Theme, deferred CompositionLocal reads, padding and background so previews render reliably. Shows interactive previews, preliminary accessibility checks, screenshot testing and PreviewParameterProvider for multiple states. Works in Android Studio; Compose Multiplatform tooling (Fleet) currently ignores annotation parameters. R8 strips preview-only code from releases.
