Base Widget

FlutterMap(
mapController: _mapController,
options: MapOptions(),
children: [],
nonRotatedChildren: [],
);
Do not use nonRotatedChildren to enforce a non-rotatable map. Instead, use interactiveFlags inside MapOptions.

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.
