props

Prop Type Default Required Description
allowUpdates bool true false If false, the camera will not send any props to the native module. Intended to be used to prevent unnecessary tile fetching and improve performance when the map is not visible. Defaults to true.
animationDuration number 2000 false The duration a camera update takes (in ms)
animationMode enum 'easeTo' false The animationstyle when the camara updates. One of: flyTo, easeTo, linearTo, moveTo
defaultSettings shape none false Default view settings applied on camera
  centerCoordinate array none false Center coordinate on map [lng, lat]
  padding shape none false Padding around edges of map in points
    paddingLeft number none false Left padding in points
    paddingRight number none false Right padding in points
    paddingTop number none false Top padding in points
    paddingBottom number none false Bottom padding in points
  heading number none false Heading on map
  pitch number none false Pitch on map
  bounds shape none false Represents a rectangle in geographical coordinates marking the visible area of the map.
The bounds.padding* properties are deprecated; use root padding property instead.
    ne array none true North east coordinate of bound
    sw array none true South west coordinate of bound
    paddingLeft number none false Left padding in points (deprecated; use root padding property instead)
    paddingRight number none false Right padding in points (deprecated; use root padding property instead)
    paddingTop number none false Top padding in points (deprecated; use root padding property instead)
    paddingBottom number none false Bottom padding in points (deprecated; use root padding property instead)
  onUserTrackingModeChange func none false Callback that is triggered on user tracking mode changes
  zoomLevel number none false Zoom level of the map
centerCoordinate array none false Center coordinate on map [lng, lat]
padding shape none false Padding around edges of map in points
  paddingLeft number none false Left padding in points
  paddingRight number none false Right padding in points
  paddingTop number none false Top padding in points
  paddingBottom number none false Bottom padding in points
heading number none false Heading on map
pitch number none false Pitch on map
bounds shape none false Represents a rectangle in geographical coordinates marking the visible area of the map.
The bounds.padding* properties are deprecated; use root padding property instead.
  ne array none true North east coordinate of bound
  sw array none true South west coordinate of bound
  paddingLeft number none false Left padding in points (deprecated; use root padding property instead)
  paddingRight number none false Right padding in points (deprecated; use root padding property instead)
  paddingTop number none false Top padding in points (deprecated; use root padding property instead)
  paddingBottom number none false Bottom padding in points (deprecated; use root padding property instead)
onUserTrackingModeChange func none false Callback that is triggered on user tracking mode changes
zoomLevel number none false Zoom level of the map
minZoomLevel number none false The minimun zoom level of the map
maxZoomLevel number none false The maximun zoom level of the map
maxBounds shape none false Restrict map panning so that the center is within these bounds
  ne array none true northEastCoordinates - North east coordinate of bound
  sw array none true southWestCoordinates - South west coordinate of bound
followUserLocation bool none false Should the map orientation follow the user's.
followUserMode enum none false The mode used to track the user location on the map. One of; "normal", "compass", "course". Each mode string is also available as a member on the MapLibreGL.UserTrackingModes object. Follow (normal), FollowWithHeading (compass), FollowWithCourse (course). NOTE: followUserLocation must be set to true for any of the modes to take effect. Example
followZoomLevel number none false The zoomLevel on map while followUserLocation is set to true
followPitch number none false The pitch on map while followUserLocation is set to true
followHeading number none false The heading on map while followUserLocation is set to true
triggerKey any none false Manually update the camera - helpful for when props did not update, however you still want the camera to move

methods

fitBounds(northEastCoordinates, southWestCoordinates[, padding][, animationDuration])

Map camera transitions to fit provided bounds

arguments
