  In this paper we establish a framework for normal approximation for white
noise functionals by Stein's method and Hida calculus. Our work is inspired by
that of Nourdin and Peccati (Probab. Theory Relat. Fields 145, 75-118, 2009),
who combined Stein's method and Malliavin calculus for normal approximation for
functionals of Gaussian processes.
