Composeum Composeum

Limitations

Composeum is already useful, but it still has a deliberate scope:

  • Android is the primary host target today.
  • @PreviewParam is basic mode by design, not a full declarative form language.
  • Rich parameter surfaces still require the DSL or preview overrides.
  • Unsupported host platforms should be treated as roadmap work, not as half-working targets.

Practical implications:

  • Start with generated previews and only introduce manual registry code where the preview experience genuinely needs it.
  • Keep function defaults authoritative for parameter defaults.
  • Treat group, tag, and variant types as identity-bearing API, not just display labels.

If a use case feels like it needs reflection or runtime scanning, it is probably pushing against the library’s intended compile-time model.
