MapControllerImpl class

Implements MapController whilst exposing methods for internal use which should not be visible to the user (e.g. for setting the current camera). This controller is for internal use. All updates to the state should be done by calling methods of this class to ensure consistency.

Constructors

MapControllerImpl.new({MapOptions? options, TickerProvider? vsync})
Constructor of the MapController implementation for internal usage.

Properties

camera → MapCamera
Get the current MapCamera instance. Prefer using MapCamera.of(context) if possible.
no setteroverride
hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
Whether any listeners are currently registered.
no setterinherited
interactiveViewerState ← MapInteractiveViewerState
Link the viewer state with the controller. This should be done once when the FlutterMapInteractiveViewerState is initialized.
no getter
isAnimating → bool
Getter that returns true if the MapControllerImpl performs a zoom, drag or rotate animation.
no setter
mapEventStream → Stream<MapEvent>
Stream of all emitted MapEvents
no setteroverride
options ↔ MapOptions
Used to change MapOptions and update the required widgets.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
value ↔ _MapControllerState
The current value stored in this notifier.

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
override
doubleTapZoomEnded(MapEventSource source) → void
To be called when a double tap zoom ends.
doubleTapZoomStarted(MapEventSource source) → void
To be called when a double tap zoom starts.
dragUpdated(MapEventSource source, Offset offset) → void
To be called when an ongoing drag movement updates.
fitCamera(CameraFit cameraFit) → bool
Move and zoom the map to fit cameraFit.
override
fitCameraRaw(CameraFit cameraFit, {Offset offset = Offset.zero}) → bool
flingAnimatedRaw({required double velocity, required Offset direction, required Offset begin, Offset offset = Offset.zero, double mass = 1, double stiffness = 1000, double ratio = 5, required bool hasGesture}) → void
Fling animation for the map. The raw method allows to set all parameters.
flingEnded(MapEventSource source) → void
To be called when a fling gesture ends.
flingNotStarted(MapEventSource source) → void
To be called when a fling gesture does not start.
flingStarted(MapEventSource source) → void
To be called when a fling gesture starts.
longPressed(MapEventSource source, TapPosition tapPosition, LatLng position) → void
Called when a long-press gesture has happened, calls the MapOptions.onLongPress callback and emits a MapEventLongPress event.
move(LatLng center, double zoom, {Offset offset = Offset.zero, String? id}) → bool
Moves and zooms the map to a center and zoom level
override
moveAndRotate(LatLng center, double zoom, double degree, {String? id}) → MoveAndRotateResult
Calls move and rotate together, but is more efficient for the combined operation
override
moveAndRotateAnimatedRaw(LatLng newCenter, double newZoom, double newRotation, {required Offset offset, required Duration duration, required Curve curve, required bool hasGesture, required MapEventSource source}) → void
Move and rotate the the map with an animation. The raw method allows to set all parameters.
moveAndRotateRaw(LatLng newCenter, double newZoom, double newRotation, {required Offset offset, required bool hasGesture, required MapEventSource source, String? id}) → MoveAndRotateResult
Internal endpoint to move, rotate and change zoom level of the MapCamera.
moveAnimatedRaw(LatLng newCenter, double newZoom, {Offset offset = Offset.zero, required Duration duration, required Curve curve, required bool hasGesture, required MapEventSource source}) → void
Animated movement of the map. The raw method allows to set all parameters.
moveEnded(MapEventSource source) → void
To be called when a drag gesture ends.
moveRaw(LatLng newCenter, double newZoom, {Offset offset = Offset.zero, required bool hasGesture, required MapEventSource source, String? id}) → bool
Internal endpoint to move the MapCamera and change zoom level.
moveStarted(MapEventSource source) → void
To be called when a gesture that causes movement starts.
nonRotatedSizeChange(MapEventSource source, MapCamera oldCamera, MapCamera newCamera) → void
To be called when the map's size constraints change.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
rotate(double degree, {String? id}) → bool
Rotates the map to a decimal degree around the current center, where 0° is North
override
rotateAnimatedRaw(double newRotation, {required Offset offset, required Duration duration, required Curve curve, required bool hasGesture, required MapEventSource source}) → void
Animated rotation of the map. The raw method allows to set all parameters.
rotateAroundPoint(double degree, {Offset? offset, String? id}) → MoveAndRotateResult
Rotates the map to a decimal degree around a custom screen point, where 0° is North
override
rotateAroundPointRaw(double degree, {required Offset? offset, required bool hasGesture, required MapEventSource source, String? id}) → MoveAndRotateResult
Internal endpoint to rotate around a point that is not in the center of the map.
rotateEnded(MapEventSource source) → void
To be called when a rotation gesture ends.
rotateRaw(double newRotation, {required bool hasGesture, required MapEventSource source, String? id}) → bool
Internal endpoint to rotate the MapCamera.
rotateStarted(MapEventSource source) → void
To be called when a rotation gesture starts.
secondaryTapped(MapEventSource source, TapPosition tapPosition, LatLng position) → void
Called when a long-press gesture has happened, calls the MapOptions.onSecondaryTap callback and emits a MapEventSecondaryTap event.
setNonRotatedSizeWithoutEmittingEvent(Size nonRotatedSize) → bool
Set the widget size but don't emit a event to the event system.
stopAnimationRaw({bool canceled = true}) → void
Stops all ongoing animations of the MapControllerImpl. This is commonly used by other gestures that should stop all ongoing movement.
tapped(MapEventSource source, TapPosition tapPosition, LatLng position) → void
Called when a long-press gesture has happened, calls the MapOptions.onTap callback and emits a MapEventTap event.
toString() → String
A string representation of this object.
