SfMapsThemeData class

Holds the color and typography values for a SfMapsTheme. Use this class to configure a SfMapsTheme widget, or to set the SfThemeData.mapsThemeData for a SfTheme widget.

To obtain the current theme, use SfMapsTheme.of.

The maps elements are,

• The "data labels", to provide information to users about the respective shape.
• The "markers", which denotes a location with built-in symbols and allows displaying custom widgets at a specific latitude and longitude on a map.
• The "bubbles", which adds information to shapes such as population density, number of users, and more. Bubbles can be rendered in different colors and sizes based on the data values of their assigned shape.
• The "legend", to provide clear information on the data plotted in the map. You can use the legend toggling feature to visualize only the shapes to which needs to be visualized.
• The "color mapping", to categorize the shapes on a map by customizing their color based on the underlying value. It is possible to set the shape color for a specific value or for a range of values.
• The "tooltip", to display additional information about shapes and bubbles using the customizable tooltip on a map.

See also:

• SfTheme and SfThemeData, for customizing the visual appearance of the maps.
