Flutter中的Google Maps Place Picker软件包错误

当我尝试在Flutter中使用 google_maps_place_picker 包运行以下代码时，我收到大量错误提示.

I am getting a huge list of error when I try to run the following code with google_maps_place_picker package in flutter.

import 'package:flutter/material.dart';
// import 'package:google_maps/google_maps.dart';
import 'package:google_maps/google_maps.dart';
import 'package:google_maps_place_picker/google_maps_place_picker.dart'
    as place;
// import 'package:location/location.dart';

import '../components/location_helper.dart';
// import '../components/location_helper.dart';

class MapScreen extends StatelessWidget {
  final LatLng location1 = LatLng(37.657, -122.776);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text('Map Screen'),
        ),
        body: Center(
          child: place.PlacePicker(
              apiKey: GOOGLE_API,
              useCurrentLocation: true,
              onPlacePicked: (result) {
                print(result.addressComponents);
                Navigator.of(context).pop();
              }),
        ));
  }
}
