*** ** * ** ***
A mutable heterogeneous map of[DynamicType](https://developer.android.com/reference/kotlin/androidx/wear/protolayout/expression/DynamicBuilders.DynamicType)keys to their corresponding values. This (and[DynamicDataMap](https://developer.android.com/reference/kotlin/androidx/wear/protolayout/expression/DynamicDataMap)) act like[MutableMap](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin.collections/-mutable-map/index.html)(and[Map](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin.collections/-map/index.html)), but with type safety for key and value pairs.
