I present the state-of-the-art of anisotropic flow fluctuations in heavy-ion collisions. Event-by-event fluctuations of flow coefficients are investigated experimentally by means of multi-particle cumulants, which are indicators of the non-Gaussian behavior of the $v_n$ distributions. After a brief review of the theoretical basis underlying cumulants and the related observables, I use selected Pb+Pb and Xe+Xe measurements to show that flow fluctuations are the key probes of the initial fluctuating geometry of the quark-gluon plasma. Eventually, I discuss what the future of flow fluctuations is in view of upcoming large-statistics LHC3 and LHC4 data.
