OptimusNavListTile class

Lists are vertically organized groups of data. Optimized for reading comprehension, a list consists of a single continuous column of rows, with each row representing a list item (in some cases on bigger viewports it could use a multi-column layout). OptimusNavListTile is meant to be used an a tile, which contains some interactable element, e.g. tile which leads to the new screen.

A list should be easily scannable, and any element of a list can be used to anchor and align list item content. Scannability is improved when elements (such as supporting visuals and headlines) are placed in consistent locations across list items. It's not recommended to mix tiles with icon, avatar or without any leading widget in the same list.
