You cam always check how the theme picker is being implemented in https://material.angular.io/ and just do the same https://github.com/angular/material.angular.io/tree/master/src/app/shared/theme-picker by doing so you will have the everlasting solution as in case any breaking changes you always can lookup material docs source how to fix.
