Flutter-Google地图，不显示我的位置 [英] Flutter - google map, does not show my location

问题描述

似乎一切都写得正确，但我不明白为什么它不能在地图上显示我的位置.

It seems to have written everything correctly but I can not understand why it does not show my location on the map.

为什么不显示我的位置?

Why is it not showing my location?

import 'package:flutter/material.dart';
import 'package:google_maps_flutter/google_maps_flutter.dart';

class MyMap extends StatefulWidget {
  @override
  MyMapState createState() => MyMapState();
}

class MyMapState extends State<MyMap> {
  GoogleMapController mapController;

  final LatLng _center = const LatLng(50.006406, 36.236484);

  void _onMapCreated(GoogleMapController controller) {
    mapController = controller;
    mapController.addMarker(
      MarkerOptions(
        position: LatLng(50.006406, 36.236484),
        infoWindowText: InfoWindowText('My Location', 'Office'),
        icon: BitmapDescriptor.defaultMarker,
      ),
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text('Map'),
          backgroundColor: Colors.green[700],
        ),
        body: GoogleMap(
          onMapCreated: _onMapCreated,
          options: GoogleMapOptions(
            scrollGesturesEnabled: true,
            tiltGesturesEnabled: true,
            rotateGesturesEnabled: true,
            myLocationEnabled: true,
            compassEnabled: true,
            cameraPosition: CameraPosition(
              target: _center,
              zoom: 11.0,
            ),
          ),
        ),
      );
  }
}

推荐答案

如果您想在地图上查看您的当前位置，并启用右下方的 FAB 功能将您带到那里，请确保您在GoogleMap窗口小部件上将属性 myLocationEnabled 设置为 true .

If you want to see your current location on the map, and enable the lower right FAB functionality that takes you there, make sure you have the property myLocationEnabled set to true on your GoogleMap Widget.

      [...]
      body: GoogleMap(
          myLocationEnabled: true,
          [...]
      )
