public fun <T> compositionLocalWithHostDefaultOf(
key: HostDefaultKey<T>
): ProvidableCompositionLocal<T>Creates a ProvidableCompositionLocal where the default value is resolved by querying the LocalHostDefaultProvider with the given key.
If a value is provided using ProvidableCompositionLocal.provides, this behaves identically to a CompositionLocal created with compositionLocalOf.
When no value is provided, the default value is resolved by querying the LocalHostDefaultProvider currently present in the composition. This mechanism allows the default value to be determined dynamically by the hosting environment (such as an Android View) rather than being hardcoded or requiring an explicit provider at the root of the composition.
This effectively acts as a bridge, decoupling the definition of the CompositionLocal from the platform-specific logic required to resolve its default. For example, a LocalViewModelStoreOwner can use this to ask the host for the owner without having a direct dependency on the Android View system.
Parameters
| key | An opaque key used to identify the requested value within the host's context. The type and meaning of the key are defined by the HostDefaultProvider implementation (e.g., on Android, this is typically a Resource ID). |
