) : SavedStateViewModel(savedStateHandle) {
    // Property
    var yourEnum: YourEnum by savedStateProperty("key")
    // LiveData
    val yourEnumLiveData: MutableLiveData<YourEnum> by savedStateLiveData("key")
}

## Support custom delegate

You can set serialization / deserialization and save / restore any type.

class YourViewModel(
    savedStateHandle: SavedStateHandle
) : SavedStateViewModel(savedStateHandle) {
    // Property
    var yourClass: YourClass by savedStateProperty<String, YourClass>({
        Json.parse(YourClass.serializer(), it)
    }, { 
        Json.stringify(YourClass.serializer(), it)
    }, "key")
// LiveData
    val yourClass: MutableLiveData<YourClass> by savedStateLiveData<String, YourClass>({ 
        Json.parse(YourClass.serializer(), it)
    }, {
