children property takes a list of Widgets, which will be stacked on top of each other (last on top). These can be any Widget, such as a FutureBuilder or StreamBuilder, but are usually Layers which are provided by this library or plugins.nonRotatedChildren property, which work similarly as their 'rotatable' counterpart, but - as the name suggests - do not get rotated as the map gets rotated. For example, the AttributionWidget should be used inside nonRotatedChildren instead of children, as it needs to remain vertical and therefore readable.
