Start by adding some Layers to children
, then configure the map in Options. Additionally, if required, add a MapController
: Controllers & Cameras.
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 Stack
s) instead of a flat-based layout (eg. using Column
s). 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.
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.
