Flutter API连接插件geiger_api_connector的使用

geiger_api_connector

geiger_api_connector是一个帮助轻松连接到 GEIGER API 的工具。

Getting Started（开始使用）

以下是如何在 Flutter 项目中使用 geiger_api_connector 插件的完整示例。

完整示例代码

import 'dart:async';
import 'dart:math' as math;

import 'package:flutter/material.dart';
import 'package:geiger_api_connector/geiger_api_connector.dart';
import 'package:multilingual_values/multilingual_values.dart';

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

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

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

class _MyHomePageState extends State<MyHomePage> {
  late GeigerApiConnector masterApiConnector;
  late GeigerApiConnector pluginApiConnector;

  @override
  void initState() {
    super.initState();
    masterApiConnector = GeigerApiConnector(
      pluginId: GeigerApi.masterId,
      pluginName: "Geiger Toolbox",
    );
    pluginApiConnector = GeigerApiConnector(
      pluginId: "com.example.plugin",
      pluginName: "Example Plugin",
    );
  }

  Future<void> _startMasterPlugin() async {
    if (!await masterApiConnector.connectToGeigerAPI()) {
      print("Failed to connect to Geiger API");
      return;
    }
    if (!await masterApiConnector.connectToLocalStorage()) {
      print("Failed to connect to Local Storage");
      return;
    }
    if (!await masterApiConnector.registerPluginListener()) {
      print("Failed to register plugin listener");
      return;
    }
    print("Master Plugin started successfully!");
  }

  Future<void> _startExternalPlugin() async {
    if (!await pluginApiConnector.connectToGeigerAPI()) {
      print("Failed to connect to Geiger API");
      return;
    }
    if (!await pluginApiConnector.connectToLocalStorage()) {
      print("Failed to connect to Local Storage");
      return;
    }
    if (!await pluginApiConnector.registerPluginListener()) {
      print("Failed to register plugin listener");
      return;
    }
    print("External Plugin started successfully!");
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Geiger API Connector Example"),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            ElevatedButton(
              onPressed: _startMasterPlugin,
              child: Text("Start Master Plugin"),
            ),
            ElevatedButton(
              onPressed: _startExternalPlugin,
              child: Text("Start External Plugin"),
            ),
            ElevatedButton(
              onPressed: () async {
                final bool result = await pluginApiConnector.sendDeviceSensorData(
                  "sensor1",
                  "100",
                  description: [
                    MultilingualValues(language: "en", value: "High Value"),
                  ],
                  urgency: "high",
                );
                if (result) {
                  print("Device sensor data sent successfully!");
                } else {
                  print("Failed to send device sensor data");
                }
              },
              child: Text("Send Device Sensor Data"),
            ),
            ElevatedButton(
              onPressed: () async {
                final bool result = await pluginApiConnector.sendUserSensorData(
                  "sensor2",
                  "50",
                  description: [
                    MultilingualValues(language: "en", value: "Medium Value"),
                  ],
                  urgency: "medium",
                );
                if (result) {
                  print("User sensor data sent successfully!");
                } else {
                  print("Failed to send user sensor data");
                }
              },
              child: Text("Send User Sensor Data"),
            ),
          ],
        ),
      ),
    );
  }
}

代码说明

1. 初始化插件：

   • 使用 GeigerApiConnector 初始化主插件和外部插件。
   • 调用 connectToGeigerAPI() 和 connectToLocalStorage() 连接到 GEIGER API 和本地存储。
   • 注册监听器以接收事件。

2. 发送设备传感器数据：

   • 使用 sendDeviceSensorData() 方法发送设备传感器数据。
   • 参数包括传感器 ID、值、描述和紧急程度。

3. 发送用户传感器数据：

   • 使用 sendUserSensorData() 方法发送用户传感器数据。
   • 参数与发送设备传感器数据类似。

4. 按钮功能：

   • 点击按钮时触发相应操作，例如启动插件或发送传感器数据。

输出示例

当点击按钮时，控制台会打印类似以下信息：

Master Plugin started successfully!
External Plugin started successfully!
Device sensor data sent successfully!
User sensor data sent successfully!
