noSuchMethod is invoked when users invoke a non-existent method
on an object. The name of the method and the arguments of the
invocation are passed to noSuchMethod in an Invocation.
If noSuchMethod returns a value, that value becomes the result of
the original invocation.
The default behavior of noSuchMethod is to throw a
NoSuchMethodError.
