strong Immediate Flat Map Mutable
abstract fun <R> strongImmediateFlatMapMutable(transform: (T) -> MutableProvider<R>): MutableProvider<R>
Creates and returns a new MutableProvider that maps to the value of the MutableProvider returned by transform.
This disables lazy evaluation of this in order to ensure that all updates of the flat-mapped provider are received.
transform should be a pure function.
