# Layers

To display anything on the map, you'll need to include at least one "layer"!

Multiple layers can be used - similar to a `Stack` - each one showing different data in different ways, from actual map tiles ([Tile Layer](/v4/layers/tile-layer.md)) to shapes on top of them ([Polygon Layer](/v4/layers/polygon-layer.md)), and even just your own custom layers ([Creating New Layers](/v4/plugins/making-a-plugin/creating-new-layers.md)).

Each layer has its own configuration and handling, but can also access the map's state/configuration, as well as be controlled by it.

Layers are usually defined in the `children` property of the `FlutterMap` - as is with the `TileLayer`, for example.&#x20;

However, the `nonRotatedChildren` property can be used for layers which shouldn't move with the map, but still require access to the map's state/configuration - for example, the `AttributionLayer`s.

{% hint style="warning" %}
Do not use `nonRotatedChildren` to enforce a non-rotatable map/`TileLayer`.

Instead, use `interactiveFlags`: [Options](/v4/usage/options.md#permanent-rules). These apply to the entire map and all layers.
