地理定位器/地理编码错误

Question

我正在通过地理定位器软件包收集GPS数据，并通过地理编码软件包将数据转换为地址。将GPS位置转换为地址后，运行iOS模拟器时，我会收到以下错误：

flutter：错误databaseexception（错误域= fmdatabase代码= 11 “数据库磁盘图像已畸形” userInfo = {nslocalizedDescription =数据库磁盘映像已畸形}） SQL“开始独家” Args []在打开，关闭...

我还运行了Android模拟器，以查看它是否与iOS相关，或者是否可以更好地解释该错误。模拟器输出一个不同的错误消息：

[错误：flutter/lib/ui/ui_dart_state.cc（209）]未经手的例外： PlatformException（io_error，发生查找的网络错误 提供的坐标（纬度：37.421998，经度： -122.084000），null，null）

  void initState() {
    super.initState();
    _requestPermission()
        .then((_) => getPositionStream())
        .catchError((error) => print(error.toString()));
    currentUser = Provider.of<UserData>(context, listen: false).currentUserId;
    _jobStream = FirebaseFirestore.instance
        .collection('jobs')
        .doc(widget.edittingJob.documentId)
        .snapshots();

  Future getPositionStream() async {
    LocationSettings locationSettings;

    if (defaultTargetPlatform == TargetPlatform.android) {
      locationSettings = AndroidSettings(
        accuracy: LocationAccuracy.high,
        distanceFilter: 10,
        forceLocationManager: true,
        intervalDuration: const Duration(seconds: 1),
      );
    } else if (defaultTargetPlatform == TargetPlatform.iOS ||
        defaultTargetPlatform == TargetPlatform.macOS) {
      locationSettings = AppleSettings(
        accuracy: LocationAccuracy.high,
        distanceFilter: 10,
        pauseLocationUpdatesAutomatically: true,
      );
    } else {
      locationSettings = LocationSettings(
        accuracy: LocationAccuracy.high,
        distanceFilter: 10,
      );
    }

    _positionStream =
        Geolocator.getPositionStream(locationSettings: locationSettings)
            .listen((Position position) async {
      List placeMarks =
          await placemarkFromCoordinates(position.latitude, position.longitude);
      setState(() {
        _address = placeMarks[0].street.toString() +
            ', ' +
            placeMarks[0].locality.toString() +
            ', ' +
            placeMarks[0].administrativeArea.toString() +
            ', ' +
            placeMarks[0].postalCode.toString() +
            ', ' +
            placeMarks[0].country.toString();
      });
    });
  }

  Future<void> _requestPermission() async {
    bool serviceEnabled;
    LocationPermission permission;

    serviceEnabled = await Geolocator.isLocationServiceEnabled();
    if (!serviceEnabled) {
      return Future.error('Location services are disabled.');
    }

    permission = await Geolocator.checkPermission();
    if (permission == LocationPermission.denied) {
      permission = await Geolocator.requestPermission();
      if (permission == LocationPermission.denied) {
        return Future.error('Location permissions are denied');
      }
    }

    if (permission == LocationPermission.deniedForever) {
      return Future.error(
          'Location permissions are permanently denied, we cannot request permissions.');
    }
  }

非常感谢任何建议！
