A consistent description of the {pi}{sup 0}{pi}{sup 0} invariant mass distribution in the {phi}(1020){yields}f{sub 0}(980){gamma}{yields}{pi}{sup 0}{pi}{sup 0}{gamma} decay and the {pi}{sup 0}{eta} in {phi}(1020){yields}a{sub 0}(980){gamma}{yields}{pi}{sup 0}{eta}{gamma} is suggested. A search for the consequences of the flavor SU(3) symmetry for the scalar mesons can be based on such an analysis. In order to accurately treat the pseudoscalar meson dynamics, which is very important for the scalar meson decays, we employ Resonance Chiral Theory.
