You can test this like you would any other error. You can pass in a function that throws the error into expect and check that it throws the right error:
const dynamic x = 'hello';
expect(() => x.notAMethod(), throwsA(isA<NoSuchMethodError>()));
Note that you will need to make your receiver (the object you are calling the method on) to be dynamic to suppress the static error that would otherwise catch this error.
