Flutter祈祷功能插件prayer的使用

一个使用Flutter/Dart构建的通用祈祷应用程序框架。

  showSubtitleOnDetailsScreen: true,
  showTabBar: true,
  tabs: const [
    PrayerTabData(
      type: PrayerTabType.prayer,
      label: 'Prayers',
      icon: Icons.question_answer_outlined,
    ),
    PrayerTabData(
      type: PrayerTabType.scripture,
      label: 'Scripture',
      icon: Icons.menu_book_outlined,
    ),
    PrayerTabData(
      type: PrayerTabType.questions,
      label: 'Questions',
      icon: Icons.help_outline,
    ),
  ],
);

final List<Prayer> prayers = [
  Prayer(
    id: 0,
    title: 'The Lord\'s Prayer',
    subTitle: 'an example prayer',
    prayerText:
        'Our Father who art in heaven, Hallowed be thy name. Thy kingdom come. Thy will be done, as in heaven, so on earth. Give us this day our daily bread. And forgive us our debts, as we also have forgiven our debtors. And bring us not into temptation, but deliver us from the evil.',
    scriptureReference: 'Matthew 6:9-13',
    scriptureText:
        'Our Father who art in heaven, Hallowed be thy name. Thy kingdom come. Thy will be done, as in heaven, so on earth. Give us this day our daily bread. And forgive us our debts, as we also have forgiven our debtors. And bring us not into temptation, but deliver us from the evil.',
    questions: [
      'What does it mean to pray to God as our Father?',
      'What does it mean to pray that God\'s kingdom come?',
      'What does it mean to pray that God\'s will be done?',
      'What does it mean to pray for our daily bread?',
      'What does it mean to pray that God would forgive us?',
      'What does it mean to pray that God would not lead us into temptation?',
    ],
  ),
];

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return PrayerApp(
      prayers: prayers,
      title: 'Example Prayer App',
      themeData: themeData,
      configuration: configuration,
    );
  }
}

说明

上述代码是一个简单的Flutter应用示例，展示了如何使用prayer插件来创建一个包含祈祷、圣经经文和问题的祈祷应用程序。以下是代码的详细解释：

  1. 导入包：

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

    导入必要的Flutter包和prayer插件。

  2. 主题数据：

    final ThemeData themeData = ThemeData(
  primarySwatch: Colors.green,
  textTheme: const TextTheme(
      // 设置文本样式
  ),
);

    定义应用的主题数据，包括颜色和字体样式。

  3. 配置参数：

    final configuration = PrayerConfiguration(
  showSubtitleOnListScreen: true,
  showSubtitleOnDetailsScreen: true,
  showTabBar: true,
  tabs: const [
    PrayerTabData(
      type: PrayerTabType.prayer,
      label: 'Prayers',
      icon: Icons.question_answer_outlined,
    ),
    PrayerTabData(
      type: PrayerTabType.scripture,
      label: 'Scripture',
      icon: Icons.menu_book_outlined,
    ),
    PrayerTabData(
      type: PrayerTabType.questions,
      label: 'Questions',
      icon: Icons.help_outline,
    ),
  ],
);

    配置祈祷应用的布局和选项，如是否显示副标题、是否显示标签栏等。

  4. 祈祷数据：

    final List<Prayer> prayers = [
  Prayer(
    id: 0,
    title: 'The Lord\'s Prayer',
    subTitle: 'an example prayer',
    prayerText: '...',
    scriptureReference: 'Matthew 6:9-13',
    scriptureText: '...',
    questions: [
      'What does it mean to pray to God as our Father?',
      'What does it mean to pray that God\'s kingdom come?',
      // 其他问题...
    ],
  ),
];

    定义祈祷数据列表，每个祈祷项包含标题、副标题、祈祷文本、圣经引用和相关问题。

  5. 主应用入口：

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return PrayerApp(
      prayers: prayers,
      title: 'Example Prayer App',
      themeData: themeData,
      configuration: configuration,
    );
  }
}

当然，关于Flutter中的prayer插件使用，这里提供一个简单的代码示例来展示如何集成和使用这个插件来获取祈祷时间。请注意，具体的插件名称和实现可能有所不同，但我会根据一般的Flutter插件使用方式来展示。

首先，确保你已经在pubspec.yaml文件中添加了prayer插件的依赖（假设有一个名为prayer_times的插件存在，实际使用时请替换为正确的插件名）：

dependencies:
  flutter:
    sdk: flutter
  prayer_times: ^x.y.z  # 替换为实际的版本号

然后，运行flutter pub get来安装依赖。

接下来，在你的Flutter应用中，你可以按照以下方式使用prayer_times插件来获取祈祷时间：

import 'package:flutter/material.dart';
import 'package:prayer_times/prayer_times.dart';  // 假设插件提供的主要类是PrayerTimes

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

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  List<String> prayerTimes = [];

  @override
  void initState() {
    super.initState();
    _fetchPrayerTimes();
  }

  Future<void> _fetchPrayerTimes() async {
    // 假设PrayerTimes类有一个方法叫calculate，需要传入经纬度、日期等参数
    double latitude = 40.7128;  // 示例经度
    double longitude = -74.0060; // 示例纬度
    DateTime date = DateTime.now();

    try {
      PrayerTimesResult result = await PrayerTimes.calculate(
        latitude: latitude,
        longitude: longitude,
        date: date,
        // 可能还有其他参数，如计算方法（如伊斯兰协会、伊斯兰开发银行等）
        method: PrayerMethod.islamicSocietyOfNorthAmerica,
      );

      // 假设结果包含一个名为times的Map，其中包含各种祈祷时间的键
      setState(() {
        prayerTimes = [
          'Fajr: ${result.times['fajr']}',
          'Sunrise: ${result.times['sunrise']}',
          'Dhuhr: ${result.times['dhuhr']}',
          'Asr: ${result.times['asr']}',
          'Maghrib: ${result.times['maghrib']}',
          'Isha: ${result.times['isha']}',
        ];
      });
    } catch (e) {
      print('Error fetching prayer times: $e');
    }
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Prayer Times'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              Text('Prayer Times for Today:', style: TextStyle(fontSize: 20)),
              SizedBox(height: 20),
              ...prayerTimes.map((time) => Text(time)).toList(),
            ],
          ),
        ),
      ),
    );
  }
}

// 假设PrayerTimesResult和PrayerMethod类是由插件提供的
class PrayerTimesResult {
  Map<String, String> times;

  PrayerTimesResult({required this.times});
}

enum PrayerMethod {
  islamicSocietyOfNorthAmerica,
  // 其他方法...
}

请注意，上述代码是一个假设性的示例，因为实际的prayer插件可能有不同的API和类结构。你需要查阅该插件的官方文档来获取正确的类名、方法名和参数。

如果插件没有提供类似PrayerTimes和PrayerTimesResult的类，你可能需要使用插件提供的具体API来调用和解析数据。通常，插件的README文件或官方文档会有详细的用法说明和示例代码。
