我们可以在Flutter中显示一些动态文本和Google地图上的标记吗？

String dynamicText = 'Hello World'; // 动态文本

Widget build(BuildContext context) {
  return Scaffold(
    body: Center(
      child: Text(dynamicText),
    ),
  );
}

dependencies:
  flutter:
    sdk: flutter
  google_maps_flutter: ^2.0.9

import 'package:flutter/material.dart';
import 'package:google_maps_flutter/google_maps_flutter.dart';

class MapScreen extends StatefulWidget {
  @override
  _MapScreenState createState() => _MapScreenState();
}

class _MapScreenState extends State<MapScreen> {
  GoogleMapController? _controller;
  Set<Marker> _markers = {};

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: GoogleMap(
        initialCameraPosition: CameraPosition(
          target: LatLng(37.42796133580664, -122.085749655962),
          zoom: 14,
        ),
        markers: _markers,
        onMapCreated: (GoogleMapController controller) {
          _controller = controller;
          setState(() {
            _markers.add(
              Marker(
                markerId: MarkerId('1'),
                position: LatLng(37.42796133580664, -122.085749655962),
                infoWindow: InfoWindow(
                  title: 'Marker 1',
                  snippet: 'This is marker 1',
                ),
              ),
            );
          });
        },
      ),
    );
  }
}
