Flutter возвращает указанный дисплей не может быть найден

Question

Я создал Google API и могу правильно определить свое местоположение (не включено в этот поток). Основная проблема заключается в том, что когда я пытаюсь добавить простой виджет GoogleMap в свое приложение, в котором вы нашли документы https://pub.dev/packages/google_maps_flutter.

Думаю, мне что-то не хватает, но я следил за каждым шагом и я не могу добавить этот виджет нигде.

У меня эта ошибка стека при попытке создать виджет GoogleMaps в моем проекте

У меня есть собственный код с виджетом GoogleMap с моим собственным местоположением, но я пытаюсь упростить все, что я закончил, используя тот же код, что и пример google_maps_flutter, и получаю ту же ошибку

main.dart

import 'package:flutter/material.dart';
import 'package:timap/src/pages/home_page.dart';
import 'package:timap/src/pages/lalalala.dart';
import 'package:timap/src/pages/match_details_page.dart';
import 'package:timap/src/pages/matches_page.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Timap',
      routes: {
        'home': (BuildContext context) => HomePage(),
        'matches': (BuildContext context) => MatchesPage(),
        'mapSample': (BuildContext context) => MapSample()
      },
      // initialRoute: 'home',
      initialRoute: 'mapSample',
    );
  }
}

lalalala.dart

    final GoogleMapController controller = await _controller.future;
    controller.animateCamera(CameraUpdate.newCameraPosition(_kLake));
  }
}
