Obtain coordinates from an address flutter

Issue

Could someone guide me to get the coordinates of an address in flutter?

I need to enter addresses in a text box and get the longitude and latitude of that address

Solution

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;
      });
    }
  }
