GetSemanticsId class Null safety

A Flutter driver command that retrieves a semantics id using a specified finder.

This command requires assertions to be enabled on the device.

If the object returned by the finder does not have its own semantics node, then the semantics node of the first ancestor is returned instead.

Throws an error if a finder returns multiple objects or if there are no semantics nodes.

Semantics must be enabled to use this method, either using a platform specific shell command or FlutterDriver.setSemantics.
