此处创建了一个Input Text Widget，当用户点击它时。

Here created an Input Text Widget and when user taps on it. This takes to google autocomplete screen, where user inputs the location.

TextFormField(
                  decoration: new InputDecoration(
                      border: InputBorder.none,
                      contentPadding: EdgeInsets.only(left: 15),
                      hintText: Strings.enter_your_house_number_street_etc,
                      hintStyle: TextStyle(
                          fontSize: 14,
                          color: AppColor.grey,
                          fontFamily: "Open Sans",
                          fontWeight: FontWeight.normal
                      )),
                  maxLines: 1,
                  controller: _address,
                onTap: ()async{
                  // then get the Prediction selected
                  Prediction p = await PlacesAutocomplete.show(
                      context: context, apiKey: kGoogleApiKey,
                  onError: onError);
                  displayPrediction(p);
                },
                )

Here it is getting the lat and long of entered location.

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

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

      var address  =detail.result.formattedAddress;

      print(lat);
      print(long);
      print(address);

      setState(() {
        _address.text = address;
      });
    }
  }
