styleURL	string	none	false	Style URL for map - notice, if non is set it will default to MapLibreGL.StyleURL.Default
styleJSON	string	none	false	StyleJSON for map - according to TileJSON specs: https://github.com/mapbox/tilejson-spec
preferredFramesPerSecond	number	none	false	iOS: The preferred frame rate at which the map view is rendered. The default value for this property is MLNMapViewPreferredFramesPerSecondDefault, which will adaptively set the preferred frame rate based on the capability of the user’s device to maintain a smooth experience. This property can be set to arbitrary integer values. Android: The maximum frame rate at which the map view is rendered, but it can't excess the ability of device hardware. This property can be set to arbitrary integer values.
localizeLabels	boolean	false	false	Automatically change the language of the map labels to the system’s preferred language, this is not something that can be toggled on/off

pitchEnabled	boolean	true	false	Enable/Disable pitch on map
rotateEnabled	boolean	true	false	Enable/Disable rotation on map
attributionEnabled	boolean	true	false	Enable/Disable attribution on map. This must be enabled for Mapbox-hosted tiles and styles. Please refer to the Mapbox Terms of Service. Other providers do not require this.
attributionPosition	`| { top?: number; left?: number }
| { top?: number; right?: number }
| { bottom?: number; left?: number }
| { bottom?: number; right?: number }`	none	false	Adds attribution offset, e.g. {top: 8, left: 8} will put attribution button in top-left corner of the map
tintColor	string | unknown[]	none	false	MapView's tintColor
