First, is there any generic term or style for this type of showcasing images/items in mobile? I'm trying to emulate the style used here but first I would like to know the proper team so that we could search if there is any library built already and avoid reinventing the wheel.
I could build something like this in mobile app (react-native), but it would be too rigid, like it would be a rows/columns of fixed images but it is no way closer than this where images have their own sizes and it seems not following the traditional row/column grid structure.
