在Flutter项目中集成高德地图，可以使用amap_map_fluttify插件。以下是一个简单的代码示例，展示了如何集成和使用该插件来显示一个基本的地图。

1. 添加依赖

首先，在你的pubspec.yaml文件中添加amap_map_fluttify依赖：

dependencies:
  flutter:
    sdk: flutter
  amap_map_fluttify: ^x.y.z  # 请替换为最新版本号

然后运行flutter pub get来安装依赖。

2. 配置Android和iOS

Android

在你的android/app/src/main/AndroidManifest.xml文件中添加必要的权限和高德地图的API Key：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.yourapp">

    <!-- 添加必要的权限 -->
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

    <!-- 高德地图API Key -->
    <application
        ... >
        <meta-data
            android:name="com.amap.api.v2.apikey"
            android:value="你的高德地图API Key"/>
        ...
    </application>

</manifest>

iOS

在你的ios/Runner/Info.plist文件中添加高德地图的API Key：

<key>io.flutter.embedded_views_preview</key>
<true/>
<key>AMapAPIKey</key>
<string>你的高德地图API Key</string>

同时，确保在ios/Podfile中启用了Swift支持（如果还没有的话）：

platform :ios, '9.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

project 'Runner', {
  'Debug': :debug,
  'Profile': :release,
  'Release': :release,
}

def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  config = use_native_modules!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))

  # Add the pods for the dependencies added to your pubspec.yaml
  pod 'amap_map_fluttify', :path => '../node_modules/amap_map_fluttify/.ios'
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '5.0'  # 或者更高版本
    end
  end
end

3. 使用高德地图插件

在你的Flutter项目中，创建一个新的Dart文件（例如map_page.dart），并添加以下代码来显示地图：

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

class MapPage extends StatefulWidget {
  @override
  _MapPageState createState() => _MapPageState();
}

class _MapPageState extends State<MapPage> {
  AmapController? _amapController;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('高德地图示例'),
      ),
      body: AmapView(
        onMapCreated: (AmapController controller) {
          _amapController = controller;
          _amapController!.moveCamera(CameraUpdate.newLatLngZoom(
            LatLng(39.9042, 116.4074), // 北京天安门坐标
            14.0,
          ));
        },
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () {
          if (_amapController != null) {
            _amapController!.showMarker(
              MarkerOption()
                ..position = LatLng(39.9042, 116.4074)
                ..title = "天安门"
                ..snippet = "北京的中心",
            );
          }
        },
        tooltip: '添加标记',
        child: Icon(Icons.add),
      ),
    );
  }
}

4. 在主应用中使用MapPage

最后，在你的主应用文件（例如main.dart）中引入并使用MapPage：

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

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter高德地图示例',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MapPage(),
    );
  }
}

这样，你就成功地在Flutter项目中集成了高德地图，并显示了一个基本的地图界面。你可以根据需要进一步自定义和扩展地图功能。
