Fultter練習 GOOGLE MAPS－工程師的雜記

在Fultter 要使用GOOGLE MAP 需要知道下面這個套件

https://pub.dev/packages/google_maps_flutter

需要注意手機模擬器上面需要把權限打開並且需要申請 GOOGLE API的KEY

https://cloud.google.com/maps-platform/

pubspec.yaml上面的設定記得要搞好

<manifest ...
  <application ...
    <meta-data android:name="com.google.android.geo.API_KEY"
               android:value="YOUR KEY HERE"/>

若要取的自己手機的位置需要用到另外一個方法或許未來會更新

目前確定可以透過拿取自己的座標點位置實現地圖監控

https://pub.dev/packages/location

GOOGLE API會有使用限制需要注意

下面為拿取手機地理位置，並回傳至WEB API 註解那段

  void initState() {
    _getLocation();

  }
  _getLocation() async {
    var location = new Location();
    location.changeSettings(accuracy: LocationAccuracy.HIGH,interval: 10000,distanceFilter: 0);
//      currentLocation = await location.getLocation();
//      print("===================================================================");
//      print(currentLocation.latitude.toString());
//      print(currentLocation.longitude.toString());
    String LocationStr="";
    location.onLocationChanged().listen((LocationData currentLocation) {
      print(currentLocation.latitude);
      print(currentLocation.longitude);
      LocationStr=currentLocation.latitude.toString()+","+currentLocation.longitude.toString();
//      var response = HttpMethod(context).makePost(globals.connectString +"/PadAccount/SetCarLocation",
//          data:{"AssignmentId":widget.postFactoryList.AssignmentId,
//            "Location":LocationStr
//          });

    });

      setState(() {}); //rebuild the widget after getting the current location of the user
  }
