Getting Started #

Installing #

Add the following to your pubspec.yaml file:

dependencies:
  flutter_osm_plugin: ^0.25.0-rc.5

Migration to 0.16.0 (Android Only) #

if you are using this plugin before Flutter 2

you should make some modification in build.gradle before that run flutter clean && flutter pub get

open file build.gradle inside android file

* change kotlin version from `1.4.21` to `1.5.21`
* change gradle version from `4.1.1` to `7.0.2`

Simple Usage #

Creating a basic OSMFlutter :

 OSMFlutter( 
        controller:mapController,
        trackMyPosition: false,
        initZoom: 12,
        minZoomLevel: 8,
        maxZoomLevel: 14,
        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,
                ),
            ),
        ),
        road: Road(
                startIcon: MarkerIcon(
                  icon: Icon(
                    Icons.person,
                    size: 64,
                    color: Colors.brown,
                  ),
                ),
                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

 MapController controller = MapController(
                            initMapWithUserPosition: false,
                            initPosition: GeoPoint(latitude: 47.4358055, longitude: 8.4737324),
                            areaLimit: BoundingBox( east: 10.4922941, north: 47.8084648, south: 45.817995, west: 5.9559113,),
                       );

2) Dispose

     controller.dispose();

3) Properties of MapController

4) Set map on user current position

 await controller.currentPosition();

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);

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>

 await controller.enableTracking();

9) Disable tracking user position

 await controller.disabledTracking();

10) update the location

this method will create marker on that specific position

 await controller.changeLocation(GeoPoint(latitude: 47.35387, longitude: 8.43609));

Change the location without create marker

 await controller.goToLocation(GeoPoint(latitude: 47.35387, longitude: 8.43609));

11) recuperation current position

 GeoPoint geoPoint = await controller.myLocation();

12) get center map b>

GeoPoint centerMap = await controller.centerMapasync;

13) select/create new position

• we have 2 way to select location in map

13.1 Manual selection (deprecated)

a) select without change default marker

 GeoPoint geoPoint = await controller.selectPosition();

b) select position with dynamic marker

• Flutter widget

 GeoPoint geoPoint = await controller.selectPosition(
     icon: MarkerIcon(
                      icon: Icon(
                        Icons.location_history,
                        color: Colors.amber,
                        size: 48,
          ), 
);

• image from network

 GeoPoint geoPoint = await controller.selectPosition(  
         imageURL: "https://raw.githubusercontent.com/PokeAPI/sprites/master/sprites/pokemon/back/1.png"
);

c) select using listener from controller directly

• for more example see home_example.dart c.1) single tap listener

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

c.2) long tap listener

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

13.2 Assisted selection (for more details see example)

 /// To Start assisted Selection
 await controller.advancedPositionPicker();
 /// To get location desired
  GeoPoint p = await controller.getCurrentPositionAdvancedPositionPicker();
  /// To get location desired and close picker
 GeoPoint p = await controller.selectAdvancedPositionPicker();
 /// To cancel assisted Selection
 await controller.cancelAdvancedPositionPicker();

14) Create Marker Programmatically

you can change marker icon by using attribute markerIcon

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

14.1) Remove marker

 await controller.removeMarker(geoPoint);

• PS : static position cannot be removed by this method

15) Draw road,recuperate distance in km and duration in sec

you can add an middle position to pass your route through them

 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,
       showMarkerOfPOI: false
   ),
);
 print("${roadInfo.distance}km");
 print("${roadInfo.duration}sec");

15.b) draw road manually

await controller.drawRoadManually(
        waysPoint,
        Colors.purpleAccent,
        6.0,
      )

16) Delete last road

 await controller.removeLastRoad();

17) 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 );

18) 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 );

19) change orientation of the map

 await controller.rotateMapCamera(degree);

20) Draw Shape in the map

• Circle

 /// to draw
 await controller.drawCircle(CircleOSM(
              key: "circle0",
              centerPoint: GeoPoint(latitude: 47.4333594, longitude: 8.4680184),
              radius: 1200.0,
              color: Colors.red,
              strokeWidth: 0.3,
            ));
 /// to remove Circle using Key
 await controller.removeCircle("circle0");

 /// to remove All Circle in the map 
 await controller.removeAllCircle();

• Rect

 /// to draw
 await controller.drawRect(RectOSM(
              key: "rect",
              centerPoint: GeoPoint(latitude: 47.4333594, longitude: 8.4680184),
              distance: 1200.0,
              color: Colors.red,
              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 :

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

mapIsReady will replace listenerMapIsReady

** 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
      }
    }
    
    //etc
}

OSMFlutter #

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 METHODS: #

1) Calculate distance between 2 geoPoint position

 double distanceEnMetres = await distance2point(GeoPoint(longitude: 36.84612143139903,latitude: 11.099388684927824,),
        GeoPoint( longitude: 36.8388023164018, latitude: 11.096959785428027, ),);

2) Get search Suggestion of text

you should know that i'm using public api, don't make lot of request

    List<SearchInfo> suggestions = await addressSuggestion("address");

show dialog picker #

simple dialog location picker to selected user location

GeoPoint p = await showSimplePickerLocation(
                      context: context,
                      isDismissible: true,
                      title: "Title dialog",
                      textConfirmPicker: "pick",
                      initCurrentUserPosition: true,
                    )

CustomLocationPicker #

customizable widget to build search location

you should use PickerMapController as controller for the widget see example : search widget

Properties of CustomLocationPicker

NOTICE: #

For now the map working only for android,iOS will be available soon

If you get ssl certfiction exception,use can use http by following instruction below

If you want to use http in Android PIE or above :

• enable useSecureURL and add android:usesCleartextTraffic="true" in your manifest like example below :

  • <application ... android:usesCleartextTraffic="true">

if you faced build error in fresh project you need to follow those instruction #40

1) remove flutter_osm_plugin from pubspec, after that pub get
2) open android module in android studio ( right click in name of project -> flutter-> open android module in android studio)
3) update gradle version to 4.1.1 ( IDE will show popup to make update)
4) update kotlin version to 1.4.21 & re-build the project
5) re-add flutter_osm_plugin in pubspec , pub get ( or flutter clean & pub get )

Before you publish your application using this library, you should take care about copyright of openStreetMap Data, that's why i add CopyrightOSMWidget see example and this issue #101
