Base Widget

mapController: MapController(),
options: MapOptions(),
children: [],
Start by adding some Layers to children, then configure the map in Options. Additionally, if required, add a MapController: Control Camera.

Placement Recommendations

It is recommended to make the map as large as possible, to allow it to display a lot of useful information easily.
As such, we recommend using a depth-based layout (eg. using Stacks) instead of a flat-based layout (eg. using Columns). The following 3rd party packages might help with creating a modern design:
If you must restrict the widget's size, you won't find a height or width property. Instead, use a SizedBox or Column/Row & Expanded.
The map widget will expand as much as possible.
To avoid errors about infinite/unspecified dimensions, ensure the map is contained within a constrained widget.

Keep Alive

If the map is displayed lazily in something like a PageView, changing the page and unloading the map will cause it to reset to its initial positioning.
To prevent this, set MapOptions.keepAlive true, which will activate an internal AutomaticKeepAliveClientMixin. This will retain the internal state container in memory, even when it would otherwise be disposed.
