Flutter地点选择器插件apple_maps_place_picker的使用

Apple Maps Place Picker

pub package likes popularity Flutter Platform

此Flutter插件提供了使用Apple Maps的可自定义地点选择器。该插件允许用户使用Apple的原生MapKit框架搜索和选择位置。

注意: 此插件仅适用于iOS,因为它使用了Apple Maps。

所有由插件提供的功能,包括地点搜索和地理编码位置,都是完全免费使用的,无需额外的API密钥或产生额外费用。与Google Maps不同,Google Maps的地点搜索功能是付费的,而Apple则免费提供这些功能,使其成为iOS应用的一个成本效益解决方案。更多详细信息,请参阅官方Apple开发者论坛讨论。

使用

基本实现

AppleMapsPlacePicker(
  initialLatitude: 40.37818,
  initialLongitude: 49.83991,
  onPlaceSelected: (Place place) {
    print('Selected place: ${place.address}');
  },
)

完全自定义

AppleMapsPlacePicker(
  initialLatitude: 40.37818,
  initialLongitude: 49.83991,
  config: PlacePickerConfig(
    searchBarConfig: SearchBarConfig(
      hintText: 'Search place',
      textFieldTextStyle: TextStyle(
        fontSize: 16,
        fontWeight: FontWeight.bold,
      ),
      backgroundColor: Colors.white,
    ),
    searchResultConfig: SearchResultConfig(
      itemTextStyle: TextStyle(
        fontSize: 16,
        color: Colors.black87,
      ),
      backgroundColor: Colors.grey[100],
    ),
    addressViewConfig: AddressViewConfig(
      confirmButtonText: 'Confirm',
      addressTextStyle: TextStyle(
        fontSize: 18,
        fontWeight: FontWeight.w300,
      ),
    ),
  ),
  onPlaceSelected: (Place place) {
    print('Selected place: ${place.address}');
  },
)

自定义标记

AppleMapsPlacePicker(
  initialLatitude: 40.37818,
  initialLongitude: 49.83991,
  onPlaceSelected: (Place place) {
    print('Selected place: ${place.address}');
  },
  customMarker: Container(
    width: 50,

  initialLatitude: 40.37818,
  initialLongitude: 49.83991,
  onPlaceSelected: (Place place) {
    print('Selected place: ${place.address}');
  },
  customBottomSheet: (Place? place) {
    return Container(
      color: Colors.white,
      padding: EdgeInsets.all(16),
      child: Column(
        children: [
          Text(place?.address ?? 'Not found'),
          ElevatedButton(
            onPressed: () {
              // 处理确认
            },
            child: Text('Confirm Location'),
          ),
        ],
      ),
    );
  },
)

当然,以下是如何在Flutter项目中使用apple_maps_place_picker插件的示例代码。这个插件允许你在iOS设备上使用Apple Maps来选择地点。请注意,这个插件目前仅支持iOS平台。

首先,你需要在你的pubspec.yaml文件中添加依赖项:

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

然后运行flutter pub get来获取依赖项。

接下来,确保你的iOS项目配置正确。由于apple_maps_place_picker依赖于Apple Maps,你需要在Info.plist中添加必要的权限请求,比如访问位置信息:

<key>NSLocationWhenInUseUsageDescription</key>
<string>需要您的位置信息来选择地点</string>

现在,你可以在你的Flutter代码中使用AppleMapsPlacePicker了。以下是一个简单的示例,展示如何打开地点选择器并处理选择的地点:

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  String selectedPlaceName = '';

  Future<void> _selectPlace() async {
    try {
      final PlaceResult result = await AppleMapsPlacePicker.showPicker(
        context,
        apiKey: 'YOUR_MAPS_API_KEY', // 如果需要API Key的话(此插件可能不需要)
        searchQuery: 'Restaurant', // 可选的搜索查询
        useCurrentLocation: true, // 是否使用当前位置作为中心点
      );

      if (result != null && result.place != null) {
        setState(() {
          selectedPlaceName = result.place.name;
        });
      }
    } catch (e) {
      print('Error selecting place: $e');
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Demo'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text(
              'Selected Place: $selectedPlaceName',
              style: TextStyle(fontSize: 20),
            ),
            SizedBox(height: 20),
            ElevatedButton(
              onPressed: _selectPlace,
              child: Text('Select Place'),
            ),
          ],
        ),
      ),
    );
  }
}

在这个示例中:

  1. 我们创建了一个简单的Flutter应用,其中包含一个按钮和一个显示所选地点名称的文本。
  2. 点击按钮时,调用_selectPlace函数,该函数使用AppleMapsPlacePicker.showPicker方法打开地点选择器。
  3. 用户选择地点后,地点信息将被返回,并更新UI中的文本。

请注意,apple_maps_place_picker插件的具体API可能会随着版本更新而变化,因此请参考其官方文档以获取最新和最准确的信息。如果插件需要API Key(尽管在撰写本文时可能不需要),请确保你已经获得了相应的API Key并正确配置。
