_TypeError(类型"List< dynamic>"不是类型"PlaceDetails"的子类型) [英] _TypeError (type 'List<dynamic>' is not a subtype of type 'PlaceDetails')

问题描述

请帮助我解决此错误:

Help me with this error:

我正在尝试从displayPrediction()获取位置值/名称并将其显示在我的textformfield中 这是来自TextFormField的电话

I am trying to get place value/name from displayPrediction() and show it in my textformfield Here is the call from TextFormField

TextFormField(
 decoration: textInputDecoration.copyWith(hintText: 'From'),
  onTap: () async {
   Prediction p = await PlacesAutocomplete.show( context: context, apiKey: kGoogleApiKey);
   displayPrediction(p);
  },
)

我想将地点保存回textformfield.
我的displayPrediction():

I want to save the place back to textformfield.
My displayPrediction():

Future<Null> displayPrediction(Prediction p) async {
    if (p != null) {
      PlacesDetailsResponse detail =
      await _places.getDetailsByPlaceId(p.placeId);

      var placeId = p.placeId;
      double lat = detail.result.geometry.location.lat;
      double lng = detail.result.geometry.location.lng;

      var address = await Geocoder.local.findAddressesFromQuery(p.description);

      print(lat);
      print(lng);
      print(address);
    }
  }

推荐答案

该错误与p.description有关.我遇到了同样的问题. 像这样使用它:

The error is with p.description. I faced the same issue. Use it like this :

List address = [];
  address.add(p.description);

  print(address);
