customSemanticsActions property Null safety
The handlers for each supported CustomSemanticsAction.
Whenever a custom accessibility action is added to a node, the action SemanticsAction.customAction is automatically added. A handler is created which uses the passed argument to lookup the custom action handler from this map and invoke it, if present.
