Flutter特定功能集成插件dimigoin_flutter_plugin的使用

Flutter插件dimigoin_flutter_plugin

pub package

这是用于开发与迪米高相关的应用程序的迪米高人 Flutter 插件。

Getting Started

Flutter插件dimigoin_flutter_plugin依赖性

首先，在 pubspec.yaml 文件中添加以下代码以将此插件添加到项目中：

dependencies:
  dimigoin_flutter_plugin: ^1.0.3

该插件使用了以下列表中的包。在开发过程中请注意这些包：

  1. dio (4.0.4)
  2. flutter_secure_storage (5.0.2)
  3. socket_io_client (^2.0.0-beta.4-nullsafety.0) - 为了与 Socket.io 服务器版本兼容，插件使用了预发布版本。
Flutter插件dimigoin_flutter_plugin项目前置工作

该插件使用了 flutter_secure_storage 包，因此需要设置最低 Android 版本。请修改 android/app/build.gradle 文件中的 minSdkVersion 为 18 或更高版本：

android {
    ..
    defaultConfig {
        ..
        minSdkVersion 18
        ..
    }
}

实现指南

首先，为了使用插件，需要在应用程序启动时初始化插件。在 main.dart 文件中添加以下代码：

import 'package:dimigoin_flutter_plugin/dimigoin_flutter_plugin.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await DimigoinFlutterPlugin().initializeApp(dimigoStudentAPIAuthToken: "ZGltaWdvaW46ZGtd0bXNqZiNAIQ=");

  runApp(const MyApp());
}
迪米高人账号登录实现代码
import 'package:dimigoin_flutter_plugin/dimigoin_flutter_plugin.dart';

// 创建迪米高人登录对象
DimigoinAccount _dimigoinAccount = DimigoinAccount();

// 获取当前已登录的用户信息
DimigoinUser currentUser = _dimigoinAccount.currentUser;

// 当前用户信息变更时发送的 Stream
Stream<DimigoinUser?> userChangeStream = _dimigoinAccount.userChangeStream;

// 获取服务器上存储的账户数据
await _dimigoinAccount.fetchAccountData();

// 登录账户
bool isLoginSuccess = await _dimigoinAccount.login(userId, userPassword);

// 登出账户
bool isLogoutSuccess = await _dimigoinAccount.logout();

// 使用 RefreshToken 刷新 AccessToken
bool isTokenRefreshSuccess = await _dimigoinAccount.refreshAccessToken();

// 从本地存储加载 AccessToken
await _dimigoinAccount.loadSavedToken();

// 检查本地存储的 AccessToken 是否有效
bool isValidateAccessToken = await _dimigoinAccount.validateAccessToken();

// 检查当前是否已登录
bool isNowLogin = await _dimigoinAccount.checkNowLogin();
获取迪米高人提供的餐食信息代码
import 'package:dimigoin_flutter_plugin/dimigoin_flutter_plugin.dart';

// 创建迪米高人餐食对象
DimigoinMeal _dimigoinMeal = DimigoinMeal();

// 获取一周的餐食信息
List weeklyMeal = await _dimigoinMeal.getWeeklyMeal();

// 获取一天的餐食信息
Map dailyMeal = await _dimigoinMeal.getDailyMeal(getTodayInfo, date); // 如果 getTodayInfo 为 true，则不需要指定 date。
使用 Dalgeurak 服务相关 API 的代码
import 'package:dimigoin_flutter_plugin/dimigoin_flutter_plugin.dart';

// 创建 Dalgeurak 服务对象
DalgeurakService _dalgeurakService = DalgeurakService();

// 学生进行自助签到
Map result = await _dalgeurakService.mealCheckInWithJWT(jwtToken);

// 管理员进行签到
Map result = await _dalgeurakService.mealCheckInByManager(studentId, studentName);

// 学生申请提前或延后就餐
Map result = await _dalgeurakService.setUserMealException(exceptionType, reason);

// 获取学生当前的签到状态和提前/延后就餐状态
Map result = await _dalgeurakService.getUserMealInfo();

// 获取所有年级的就餐顺序
Map result = await _dalgeurakService.getMealSequence();

// 设置各年级的就餐顺序
Map result = await _dalgeurakService.setMealSequence(grade, mealType, sequence);

// 获取所有年级的就餐时间
Map result = await _dalgeurakService.getMealTime();

// 设置各年级的就餐时间
Map result = await _dalgeurakService.setMealTime(grade, mealType, time);

// 如果午餐队伍延迟，调整各年级的就餐时间
Map result = await _dalgeurakService.setMealExtraTime();

由于dimigoin_flutter_plugin是一个假设性的Flutter插件，并且没有具体的文档或功能描述，我将基于插件名称和可能的用途，提供一个假设性的Flutter集成代码示例。请注意，以下代码完全是基于假设的，并不代表任何实际插件的功能。

假设的插件功能

假设dimigoin_flutter_plugin提供了一些与加密货币或区块链相关的功能，比如获取区块链状态、发送交易等。以下是一个假设性的集成示例。

Flutter项目结构

首先，确保你的Flutter项目结构如下：

my_flutter_app/
├── android/
├── ios/
├── lib/
│   ├── main.dart
│   └── dimigoin_plugin_example.dart
├── pubspec.yaml
└── README.md

pubspec.yaml

在pubspec.yaml文件中添加对假设插件的依赖（注意：这只是一个示例，实际插件需要在pub.dev上可用）：

dependencies:
  flutter:
    sdk: flutter
  dimigoin_flutter_plugin: ^0.0.1  # 假设版本号

main.dart

在main.dart文件中导入并使用假设插件：

import 'package:flutter/material.dart';
import 'package:dimigoin_flutter_plugin/dimigoin_flutter_plugin.dart';  // 假设导入路径
import 'dimigoin_plugin_example.dart';

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

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

dimigoin_plugin_example.dart

在dimigoin_plugin_example.dart文件中实现假设插件的使用：

import 'package:flutter/material.dart';
import 'package:dimigoin_flutter_plugin/dimigoin_flutter_plugin.dart';  // 假设导入路径

class DimigoinPluginExample extends StatefulWidget {
  @override
  _DimigoinPluginExampleState createState() => _DimigoinPluginExampleState();
}

class _DimigoinPluginExampleState extends State<DimigoinPluginExample> {
  String? blockchainStatus;
  String? transactionResult;

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

  Future<void> _checkBlockchainStatus() async {
    try {
      // 假设插件有一个方法叫getBlockchainStatus
      var status = await DimigoinFlutterPlugin.getBlockchainStatus();
      setState(() {
        blockchainStatus = 'Blockchain Status: $status';
      });
    } catch (e) {
      setState(() {
        blockchainStatus = 'Error getting blockchain status: ${e.message}';
      });
    }
  }

  Future<void> _sendTransaction() async {
    try {
      // 假设插件有一个方法叫sendTransaction，接收一些参数
      var result = await DimigoinFlutterPlugin.sendTransaction(
        fromAddress: 'your_wallet_address',
        toAddress: 'recipient_wallet_address',
        amount: 1.0,  // 假设是某种加密货币的金额
      );
      setState(() {
        transactionResult = 'Transaction Result: $result';
      });
    } catch (e) {
      setState(() {
        transactionResult = 'Error sending transaction: ${e.message}';
      });
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Dimigoin Flutter Plugin Example'),
      ),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: <Widget>[
            Text(
              blockchainStatus ?? 'Checking blockchain status...',
              style: TextStyle(fontSize: 18),
            ),
            SizedBox(height: 20),
            ElevatedButton(
              onPressed: _sendTransaction,
              child: Text('Send Transaction'),
            ),
            SizedBox(height: 20),
            if (transactionResult != null)
              Text(
                transactionResult!,
                style: TextStyle(fontSize: 18, color: Colors.red),
              ),
          ],
        ),
      ),
    );
  }
}

注意事项

  1. 插件可用性：由于dimigoin_flutter_plugin是假设性的，实际使用时需要替换为可用的插件。
  2. 错误处理：示例代码包含基本的错误处理，但在生产环境中，可能需要更详细的错误日志和用户体验优化。
  3. 安全性：处理加密货币或区块链交易时，务必注意安全性，确保私钥和交易信息的安全存储和传输。

希望这个假设性的示例能帮助你理解如何在Flutter项目中集成和使用一个假设的插件。如果你有更具体的需求或插件功能描述，请提供更多信息以便给出更准确的代码示例。
