Enro

Enro is a powerful navigation library for Kotlin Multiplatform — Android, iOS, Desktop and Web — built around a simple idea: screens within an application should behave like functions.

A NavigationKey is the signature of a screen. It declares the screen’s inputs, and optionally a typed result. Calling code never needs to know how the screen is implemented; it just invokes the contract.

@Serializable
data class ShowProfile(val userId: String) : NavigationKey

@Serializable
data class SelectDate(
    val minDate: LocalDate? = null,
    val maxDate: LocalDate? = null,
) : NavigationKey.WithResult<LocalDate>

If you read those as function signatures:

fun showProfile(userId: String): Unit
fun selectDate(minDate: LocalDate? = null, maxDate: LocalDate? = null): LocalDate

Enro is Compose-first and Kotlin Multiplatform. On Android, a compatibility layer (enro-compat) keeps existing Fragments and Activities working alongside Compose destinations, so you can adopt Enro incrementally.

Applications using Enro

“The novices’ eyes followed the wriggling path up from the well as it swept a great meandering arc around the hillside. Its stones were green with moss and beset with weeds. Where the path disappeared through the gate they noticed that it joined a second track of bare earth, where the grass appeared to have been trampled so often that it ceased to grow. The dusty track ran straight from the gate to the well, marred only by a fresh set of sandal-prints that went down, and then up, and ended at the feet of the young monk who had fetched their water.” — The Garden Path
