当前位置动摇 [英] Current location with flutter

问题描述

我在检索当前位置时遇到问题.

I am having issue with retrieve the current location.

第1步:当我按下按钮时，它将打开用于启用位置服务的默认弹出窗口，因为我检查它没有启用位置.

Step 1: when i press a button it will open the default popup for enable the location service,as i inspected it doesn't enable the location.

第2步:如果我手动启用该位置，我会得到当前位置，如果我执行了第一步，它将不起作用

Step 2: If i enable the location manually i am getting the current location,if i do the first step it doesn't work

       final Location location = Location();

  LocationData _location;
  String _error;

  Future<void> _getLocation() async {
    setState(() {
      _error = null;
    });
    try {
      final LocationData _locationResult = await location.getLocation();
      setState(() {
        _location = _locationResult;
      });
    } on PlatformException catch (err) {
      setState(() {
        _error = err.code;
      });
    }
  }
 

推荐答案

这是如何使用位置信息包获取位置信息的示例

This is a sample of how to get the location using the location package

Future _getLocation() async {
    Location location = new Location();
    LocationData _pos = await location.getLocation();
    SharedPrefrence().setLatitude(_pos.latitude);
    SharedPrefrence().setLongitude(_pos.longitude);
}
