Simple Usage

Creating a basic `OSMFlutter` :

 OSMFlutter( 
        controller:mapController,
        osmOption: OSMOption(
              userTrackingOption: UserTrackingOption(
              enableTracking: true,
              unFollowUser: false,
            ),
            zoomOption: ZoomOption(
                  initZoom: 8,
                  minZoomLevel: 3,
                  maxZoomLevel: 19,
                  stepZoom: 1.0,
            ),
            userLocationMarker: UserLocationMaker(
                personMarker: MarkerIcon(
                    icon: Icon(
                        Icons.location_history_rounded,
                        color: Colors.red,
                        size: 48,
                    ),
                ),
                directionArrowMarker: MarkerIcon(
                    icon: Icon(
                        Icons.double_arrow,
                        size: 48,
                    ),
                ),
            ),
            roadConfiguration: RoadOption(
                    roadColor: Colors.yellowAccent,
            ),
            markerOption: MarkerOption(
                defaultMarker: MarkerIcon(
                    icon: Icon(
                      Icons.person_pin_circle,
                      color: Colors.blue,
                      size: 56,
                    ),
                )
            ),
        )
    );

MapController

Declare MapController to control OSM map

1) Initialisation

Note using the default constructor, you should use initMapWithUserPosition or initPosition if you want the map to initialize using static position use the named constructor withPosition or if you want to initialize the map with user position use withUserPosition

// default constructor
 MapController controller = MapController(
                            initPosition: GeoPoint(latitude: 47.4358055, longitude: 8.4737324),
                            areaLimit: BoundingBox( 
                                east: 10.4922941, 
                                north: 47.8084648, 
                                south: 45.817995, 
                                west:  5.9559113,
                      ),
            );
// or set manually init position
 final controller = MapController.withPosition(
            initPosition: GeoPoint(
              latitude: 47.4358055,
              longitude: 8.4737324,
          ),
);
// init the position using the user location
final controller = MapController.withUserPosition(
        trackUserLocation: UserTrackingOption(
           enableTracking: true,
           unFollowUser: false,
        )
)

// init the position using the user location and control map from outside
final controller = MapController.withUserPosition(
        trackUserLocation: UserTrackingOption(
           enableTracking: true,
           unFollowUser: false,
        ),
         useExternalTracking: true
)

2) Dispose

     controller.dispose();

3) Properties of default MapController

MapController has 2 named Constructor MapController.withPosition, MapController.withUserPosition to control initialization of the Map

Properties	Description
`initMapWithUserPosition`	(UserTrackingOption?) initialize map with user position
`initPosition`	(GeoPoint) if it isn't null, the map will be pointed at this position
`areaLimit`	(Bounding) set area limit of the map (default BoundingBox.world())
`customLayer`	(CustomTile) set customer layer using different osm server , this attribute used only with named constructor `customLayer`
`useExternalTracking`	(bool) if true,we will disable our logic to show userlocation marker or to move to the user position

3.1) Custom Layers with MapController

To change the tile source in OSMFlutter, you should used our named constructor customLayer, see the example below


controller = MapController.customLayer(
      initPosition: GeoPoint(
        latitude: 47.4358055,
        longitude: 8.4737324,
      ),
      customTile: CustomTile(
        sourceName: "opentopomap",
        tileExtension: ".png",
        minZoomLevel: 2,
        maxZoomLevel: 19,
        urlsServers: [
         TileURLs(
            //"https://tile.opentopomap.org/{z}/{x}/{y}"
            url: "https://tile.opentopomap.org/",
            subdomains: [],
          )
        ],
        tileSize: 256,
      ),
    )

also,you can use our predefined custom tiles like
cyclOSMLayer constructor for cycling tiles
publicTransportationLayer constructor for transport tiles ,it's public osm server
we support full server path like ("https://tile.opentopomap.org/{z}/{x}/{y}")

For more example see our example in home_example.dart

3.2) Change Layers in runtime

 await controller.changeTileLayer(tileLayer: CustomTile(...));

4) Set map on user current location

 await controller.currentLocation();

5) Zoom IN

 await controller.setZoom(stepZoom: 2);
 // or 
 await controller.zoomIn();

5.1) Zoom Out

 await controller.setZoom(stepZoom: -2);
 // or 
 await controller.zoomOut();

5.2) change zoom level

zoomLevel should be between minZoomLevel and maxZoomLevel

 await controller.setZoom(zoomLevel: 8);

5.3) zoom to specific bounding box

await controller.zoomToBoundingBox(BoundingBox(),paddingInPixel:0)

Note :

For the box attribute ,If you don't have bounding box,you can use list of geopoint like this BoundingBox.fromGeoPoints

6) get current zoom level b>

await controller.getZoom();

7) BoundingBox

set bounding box in the map

await controller.limitAreaMap(BoundingBox( east: 10.4922941, north: 47.8084648, south: 45.817995, west: 5.9559113,));

remove bounding box in the map

await controller.removeLimitAreaMap();

8) Track user current position

for iOS,you should add those line in your info.plist file

   <key>NSLocationWhenInUseUsageDescription</key>
	<string>any text you want</string>
	<key>NSLocationAlwaysUsageDescription</key>
	<string>any text you want</string>

from version 0.40.0 we can call only enableTracking will animate to user location without need to call currentLocation

when enableStopFollow is true,map will not be centered if the user location changed

you can disable rotation of personIcon using disableUserMarkerRotation (default: false)

 await controller.enableTracking(enableStopFollow:false,);

use this method below if you want to control the map(move to the user location and show the marker) while receiving the user location

 await controller.startLocationUpdating();

9) Disable tracking user position

 await controller.disabledTracking();

use this method below if you already used startLocationUpdating

 await controller.stopLocationUpdating();

10) update the location

Change the location without create marker

 await controller.moveTo(GeoPoint(latitude: 47.35387, longitude: 8.43609),animate:true);

11) recuperation current position

 GeoPoint geoPoint = await controller.myLocation();

12) get center map

GeoPoint centerMap = await controller.centerMap;

12.1) get geoPoint in the map

recuperate geoPoint of marker add it by user except static points

List<GeoPoint> geoPoints = await controller.geopoints;

13) get bounding box map

BoundingBox bounds = await controller.bounds;

14) Map Listener

Get GeoPoint from listener from controller directly (for more example: see home_example.dart )

a.1) single tap listener

controller.listenerMapSingleTapping.addListener(() {
      if (controller.listenerMapSingleTapping.value != null) {
        /// put you logic here
      }
    });

a.2) long tap listener

controller.listenerMapLongTapping.addListener(() {
      if (controller.listenerMapLongTapping.value != null) {
        /// put you logic here
      }
    });

a.3) region change listener

controller.listenerRegionIsChanging.addListener(() {
      if (controller.listenerRegionIsChanging.value != null) {
        /// put you logic here
      }
    });

15) Create Marker Programmatically

you can change marker icon by using attribute markerIcon the angle value should be between 0,2pi set anchor of ther Marker

await controller.addMarker(GeoPoint,
      markerIcon:MarkerIcon,
      angle:pi/3,
      anchor:IconAnchor(anchor: Anchor.top,)
);

15.1) Update Marker

you can change the location,icon,angle,anchor of the specific marker

The old configuration of the Marker will be keep it the same if not specificied

await controller.changeLocationMarker(oldGeoPoint,newGeoPoint,MarkerIcon,angle,IconAnchor);

15.2) Change Icon Marker

You can change marker icon by using attribute markerIcon of existing Marker The GeoPoint/Marker should be exist

await controller.setMarkerIcon(GeoPoint,MarkerIcon);

15.3) Remove marker

 await controller.removeMarker(geoPoint);

PS : static position cannot be removed by this method

16) Draw road,recuperate instructions ,distance in km and duration in sec

you can add an middle position to pass your route through them change configuration of the road in runtime zoom into the region of the road change the type of the road that user want to use

 RoadInfo roadInfo = await controller.drawRoad( 
   GeoPoint(latitude: 47.35387, longitude: 8.43609),
   GeoPoint(latitude: 47.4371, longitude: 8.6136),
   roadType: RoadType.car,
   intersectPoint : [ GeoPoint(latitude: 47.4361, longitude: 8.6156), GeoPoint(latitude: 47.4481, longitude: 8.6266)]
   roadOption: RoadOption(
       roadWidth: 10,
       roadColor: Colors.blue,
       zoomInto: true,
   ),
);
 print("${roadInfo.distance}km");
 print("${roadInfo.duration}sec");
 print("${roadInfo.instructions}");

properties of `RoadOption`

Properties	Description
`roadColor`	(Color) required Field, change the default color of the route in runtime
`roadWidth`	(double) change the road width, default value 5.0
`roadBorderColor`	(Color?) set color of border polyline
`roadBorderWidth`	(double?) set border width of polyline, if width null or 0,polyline will drawed without border
`zoomInto`	(bool) change zoom level to make the all the road visible (default:true)
`isDotted`	(bool) to draw dotted polyline (default: false)

Note drawing dotted polyline has limitation on web where we cannot draw dotted poyline with borderWidth > 0

16.b) draw road manually

await controller.drawRoadManually(
        waysPoint,
        interestPointIcon: MarkerIcon(
          icon: Icon(
            Icons.location_history,
            color: Colors.black,
          ),
        ),
        interestPoints: [waysPoint[3],waysPoint[6]],
        zoomInto: true
)

17) Delete last road

 await controller.removeLastRoad();

18) draw multiple roads

final configs = [
      MultiRoadConfiguration(
        startPoint: GeoPoint(
          latitude: 47.4834379430,
          longitude: 8.4638911095,
        ),

            latitude: 47.3982152237,
            longitude: 8.4129691189,
          ),
          roadOptionConfiguration: MultiRoadOption(
            roadColor: Colors.orange,
          )),
      MultiRoadConfiguration(
        startPoint: GeoPoint(
          latitude: 47.4519015578,
          longitude: 8.4371175094,
        ),
        destinationPoint: GeoPoint(
          latitude: 47.4321999727,
          longitude: 8.5147623089,
        ),
      ),
    ];
    await controller.drawMultipleRoad(
      configs,
      commonRoadOption: MultiRoadOption(
        roadColor: Colors.red,
      ),
    );

19) delete all roads

 await controller.clearAllRoads();

20) Change static GeoPoint position

add new staticPoints with empty list of geoPoints (notice: if you add static point without marker,they will get default maker used by plugin)

change their position over time

change orientation of the static GeoPoint with GeoPointWithOrientation

 await controller.setStaticPosition(List<GeoPoint> geoPoints,String id );

21) Change/Add Marker old/new static GeoPoint position

add marker of new static point

change their marker of existing static geoPoint over time

 await controller.setMarkerOfStaticPoint(String id,MarkerIcon markerIcon );

22) change orientation of the map

 await controller.rotateMapCamera(degree);

23) Draw Shape in the map

Circle

              strokeWidth: 0.3,
            ));
 /// to remove Rect using Key
 await controller.removeRect("rect");

 /// to remove All Rect in the map 
 await controller.removeAllRect();

remove all shapes in the map

 await controller.removeAllShapes();

Interfaces:

OSMMixinObserver :

contain listener methods to get event from native map view like when mapIsReady,mapRestored

you should add ths line controller.addObserver(this); in initState

override mapIsReady to implement your own logic after initialisation of the map

mapIsReady will replace listenerMapIsReady

Methods	Description
`mapIsReady`	(callback) Should be override this method, to get notified when map is ready to go or not
`mapRestored`	(callback) Should be override this method, to get notified when map is restored you can also add you backup
`onSingleTap`	(callback) Called when the user makes single click on map
`onLongTap`	(callback) Called when the user makes long click on map
`onRegionChanged`	(callback) Notified when map is change region (on moves)
`onRoadTap`	(callback) Notified when user click on the polyline (road)
`onLocationChanged`	(callback) Notified when user location changed

** example

class YourOwnStateWidget extends State<YourWidget> with OSMMixinObserver {

   //etc
  @override
  void initState() {
    super.initState();
    controller.addObserver(this);
  }
    @override
    Future<void> mapIsReady(bool isReady) async {
      if (isReady) {
        /// put you logic
      }
    }
  @override
  Future<void> mapRestored() async {
    super.mapRestored();
    /// TODO

Custom Controller

To create your own MapController to need to extends from BaseMapController, if you want to make a custom initialization to need to call init() and put your code after super.init()

example

class CustomMapController extends BaseMapController {

  @override
  void dispose() {
    /// TODO put you logic here
    super.dispose();
  }

  @override
  void init() {
    super.init();
    /// TODO put you logic here
  }
}

STATIC Map:

using OSMViewer we can show static map that contain on location

OSMViewer(
        controller: SimpleMapController(
          initPosition: GeoPoint(
              latitude: 47.4358055,
              longitude: 8.4737324,
          ),
        markerHome: const MarkerIcon(
            icon: Icon(Icons.home),
          ),
        ),
        zoomOption: const ZoomOption(
        initZoom: 16,
        minZoomLevel: 11,
