Flutter电池电量获取插件flutter_get_device_battery_percent的使用

Flutter电池电量获取插件flutter_get_device_battery_percent的使用

这是一个用于获取设备电池电量的新插件项目。

开始使用

此项目是一个用于Flutter的插件包的起点，该插件包包括Android和/或iOS的平台特定实现代码。

对于开始进行Flutter开发的帮助，可以查看在线文档，其中包含教程、示例、移动开发指南和完整的API引用。

完整示例代码

以下是使用flutter_get_device_battery_percent插件的完整示例代码：

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

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

class MyApp extends StatefulWidget {
  [@override](/user/override)
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final batteryService = FlutterGetDeviceBatteryPercent();
  String currentBatteryLevel = "按按钮获取电池电量";
  String formattedDateTime = "按按钮获取格式化日期时间";

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Flutter插件示例'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              Text("当前电池电量为: $currentBatteryLevel%"),
              const SizedBox(height: 20,),
              Text("格式化日期时间为: $formattedDateTime"),
              const SizedBox(height: 20,),
              ElevatedButton(
                onPressed: () async {
                  int? batteryLevel = await batteryService.getBatteryLevel();
                  print('电池电量: $batteryLevel');
                  setState(() {
                    currentBatteryLevel = batteryLevel?.toString() ?? "错误";
                  });
                },
                child: const Text('获取电池电量'),
              ),
              ElevatedButton(
                onPressed: () async {
                  String? formattedDate = await batteryService.getFormattedDateTime('2023-06-20 15:30:00');
                  print('格式化日期时间: $formattedDate');
                  setState(() {
                    formattedDateTime = formattedDate ?? "错误";
                  });
                },
                child: const Text('获取格式化日期时间'),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

代码说明

1. 导入库:

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

   导入Flutter核心库和自定义插件库。

2. 初始化应用:

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

   初始化并运行应用。

3. 创建状态管理类:

   class MyApp extends StatefulWidget {
     [@override](/user/override)
     _MyAppState createState() => _MyAppState();
   }
   
   class _MyAppState extends State<MyApp> {
   

   创建一个状态管理类来管理UI状态。

4. 初始化电池服务对象:

   final batteryService = FlutterGetDeviceBatteryPercent();
   

5. 构建UI:

   [@override](/user/override)
   Widget build(BuildContext context) {
     return MaterialApp(
       home: Scaffold(
         appBar: AppBar(
           title: const Text('Flutter插件示例'),
         ),
         body: Center(
           child: Column(
             mainAxisAlignment: MainAxisAlignment.center,
             children: [
               Text("当前电池电量为: $currentBatteryLevel%"),
               const SizedBox(height: 20,),
               Text("格式化日期时间为: $formattedDateTime"),
               const SizedBox(height: 20,),
               ElevatedButton(
                 onPressed: () async {
                   int? batteryLevel = await batteryService.getBatteryLevel();
                   print('电池电量: $batteryLevel');
                   setState(() {
                     currentBatteryLevel = batteryLevel?.toString() ?? "错误";
                   });
                 },
                 child: const Text('获取电池电量'),
               ),
               ElevatedButton(
                 onPressed: () async {
                   String? formattedDate = await batteryService.getFormattedDateTime('2023-06-20 15:30:00');
                   print('格式化日期时间: $formattedDate');
                   setState(() {
                     formattedDateTime = formattedDate ?? "错误";
                   });
                 },
                 child: const Text('获取格式化日期时间'),
               ),
             ],
           ),
         ),
       ),
     );
   }
