# requiredFlows

`open val requiredFlows: Map<String, Set<String>>`

A Map with an entry for each consumed flow used by the webAPIs. The key of each map entry should contain the FlowLogic class name. The associated map values are the union of all concrete class names passed to the flow constructor. Standard java.lang.* and kotlin.* types do not need to be included explicitly. This is used to extend the white listed flows that can be initiated from the ServiceHub invokeFlowAsync method.
