dexcom_flutter 是一个用于在 Flutter 应用中集成 Dexcom 血糖监测数据的插件。通过这个插件，你可以获取用户的血糖数据、趋势信息等。以下是如何使用 dexcom_flutter 插件的基本步骤：

1. 添加依赖

首先，你需要在 pubspec.yaml 文件中添加 dexcom_flutter 插件的依赖：

dependencies:
  flutter:
    sdk: flutter
  dexcom_flutter: ^1.0.0  # 请使用最新版本

然后运行 flutter pub get 来安装依赖。

2. 初始化插件

在你的 Dart 文件中，导入 dexcom_flutter 插件并初始化它。

import 'package:dexcom_flutter/dexcom_flutter.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: DexcomExample(),
    );
  }
}

class DexcomExample extends StatefulWidget {
  @override
  _DexcomExampleState createState() => _DexcomExampleState();
}

class _DexcomExampleState extends State<DexcomExample> {
  final DexcomFlutter _dexcomFlutter = DexcomFlutter();

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

  Future<void> _initDexcom() async {
    try {
      await _dexcomFlutter.initialize(
        clientId: 'YOUR_CLIENT_ID',
        clientSecret: 'YOUR_CLIENT_SECRET',
        redirectUri: 'YOUR_REDIRECT_URI',
      );
    } catch (e) {
      print('Failed to initialize Dexcom: $e');
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Dexcom Example'),
      ),
      body: Center(
        child: Text('Dexcom Initialized'),
      ),
    );
  }
}

3. 登录并获取数据

在初始化插件之后，你需要让用户登录以获取访问令牌，然后才能获取血糖数据。

Future<void> _login() async {
  try {
    await _dexcomFlutter.login();
    _fetchData();
  } catch (e) {
    print('Failed to login: $e');
  }
}

Future<void> _fetchData() async {
  try {
    final glucoseData = await _dexcomFlutter.getGlucoseReadings();
    print('Glucose Data: $glucoseData');
  } catch (e) {
    print('Failed to fetch glucose data: $e');
  }
}

4. 处理数据

你可以通过 getGlucoseReadings 方法获取用户的血糖数据。这个方法返回一个包含血糖读数、时间戳等信息的列表。

5. 登出

当用户不再需要使用 Dexcom 服务时，你可以调用 logout 方法来清除用户的登录状态。

Future<void> _logout() async {
  try {
    await _dexcomFlutter.logout();
    print('Logged out successfully');
  } catch (e) {
    print('Failed to logout: $e');
  }
}
