Measurements of the azimuthal anisotropy in lead-lead collisions at$\sqrt{s_\mathrm{NN}} = 5.02$ TeV are presented using a data samplecorresponding to 0.49 $\mathrm{nb}^{-1}$ integrated luminosity collected by theATLAS experiment at the LHC in 2015. The recorded minimum-bias sample isenhanced by triggers for "ultra-central" collisions, providing an opportunityto perform detailed study of flow harmonics in the regime where the initialstate is dominated by fluctuations. The anisotropy of the charged-particleazimuthal angle distributions is characterized by the Fourier coefficients,$v_{2}-v_{7}$, which are measured using the two-particle correlation,scalar-product and event-plane methods. The goal of the paper is to providemeasurements of the differential as well as integrated flow harmonics $v_{n}$over wide ranges of the transverse momentum, 0.5 $<p_{\mathrm{T}}<$ 60 GeV, thepseudorapidity, $|\eta|<$ 2.5, and the collision centrality $0-80$%. Resultsfrom different methods are compared and discussed in the context of previousand recent measurements in Pb+Pb collisions at $\sqrt{s_\mathrm{NN}} = 2.76$TeV and 5.02 TeV. In particular, the shape of the $p_{\mathrm{T}}$ dependenceof elliptic or triangular flow harmonics is observed to be very similar atdifferent centralities after scaling the $v_{n}$ and $p_{\mathrm{T}}$ values byconstant factors over the centrality interval $0-60$% and the $p_{\mathrm{T}}$range $0.5 < p_{\mathrm{T}} < 5$ GeV.
