Multiplatform support

[ZacSweers]

Would start with Desktop and then move to iOS

Areas that need investigation

• KMP Paging lib https://github.com/cashapp/multiplatform-paging
• Audit use of direct android APIs that have KMP alternatives
  • Common ones are things like Context, SuppressLint, etc
• What does a Desktop CatchUp look like? Is it landscape with panels or is it just a windowed phone app?
• iOS would require migrating off of Anvil and Dagger 😬. Perhaps github.com/evant/kotlin-inject, but no replacement for anvil currently. Same with Circuit code gen.
• Debug screen has most android-specific APIs, maybe that goes later
• Android-only dependencies
  • Image loading (Coil is building something I think?)
• JVM-only dependencies
  • Retrofit, Eithernet, other
• Resources
  • Probably some combination of Lyricist and moko-resources?

Coil doesn't yet support multiplatform, but they're working on it.

I opted for an expect/actual delegating to Coil for Android, and a very naive manual implementation for desktop AsyncImagePainter.kt
