ConfigKey

A typed remote config key with a compiled-in default.

Unlike Novalingo's original version, this generic ConfigKey carries no built-in registry — apps own their own object AppConfigKeys { val ALL_KEYS = listOf(...) } and pass it to whatever debug override UI they build on top of RemoteConfigClient.allValues.

Construction validates that defaultValue matches valueType (and, for constrained string keys, that the default is one of allowedValues), so a mistyped key fails at startup instead of silently resolving the wrong type later. Prefer the typed factories:

object AppConfigKeys {
    val NEW_ONBOARDING = ConfigKey.bool("new_onboarding", "Show the redesigned onboarding", false)
    val THEME = ConfigKey.string("theme", "UI theme", "system", allowedValues = listOf("light", "dark", "system"))
    val ALL_KEYS = listOf(NEW_ONBOARDING, THEME)
}
