void fetchData() async {
  var response = await TechlifyHttp.get('https://jsonplaceholder.typicode.com/posts');
  print(response.body);
}

2.2 本地存储

techlify_core 提供了基于 SharedPreferences 的本地存储工具类，方便进行数据的持久化存储。

import 'package:techlify_core/techlify_core.dart';

void saveData() async {
  await TechlifyStorage.setString('key', 'value');
}

void getData() async {
  String value = await TechlifyStorage.getString('key');
  print(value);
}

2.3 日志记录

techlify_core 提供了一个简单的日志记录工具类，支持不同级别的日志输出。

import 'package:techlify_core/techlify_core.dart';

void logMessage() {
  TechlifyLogger.d('This is a debug message');
  TechlifyLogger.i('This is an info message');
  TechlifyLogger.w('This is a warning message');
  TechlifyLogger.e('This is an error message');
}

2.4 设备信息

techlify_core 提供了获取设备信息的工具类，方便获取设备的型号、操作系统版本等信息。

import 'package:techlify_core/techlify_core.dart';

void getDeviceInfo() async {
  String deviceModel = await TechlifyDeviceInfo.getDeviceModel();
  String osVersion = await TechlifyDeviceInfo.getOsVersion();
  print('Device Model: $deviceModel, OS Version: $osVersion');
}

2.5 权限管理

techlify_core 提供了简化的权限管理工具类，方便请求和检查应用权限。

import 'package:techlify_core/techlify_core.dart';

void requestPermission() async {
  bool granted = await TechlifyPermissions.request(Permission.camera);
  if (granted) {
    print('Camera permission granted');
  } else {
    print('Camera permission denied');
  }
}

3. 使用示例

以下是一个简单的示例，展示了如何使用 techlify_core 插件的各项功能：

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

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

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Techlify Core Example'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              ElevatedButton(
                onPressed: fetchData,
                child: Text('Fetch Data'),
              ),
              ElevatedButton(
                onPressed: saveData,
                child: Text('Save Data'),
              ),
              ElevatedButton(
                onPressed: getData,
                child: Text('Get Data'),
              ),
              ElevatedButton(
                onPressed: logMessage,
                child: Text('Log Message'),
              ),
              ElevatedButton(
                onPressed: getDeviceInfo,
                child: Text('Get Device Info'),
              ),
              ElevatedButton(
                onPressed: requestPermission,
                child: Text('Request Permission'),
              ),
            ],
          ),
        ),
      ),
    );
  }

  void fetchData() async {
    var response = await TechlifyHttp.get('https://jsonplaceholder.typicode.com/posts');
    print(response.body);
  }

  void saveData() async {
    await TechlifyStorage.setString('key', 'value');
  }

  void getData() async {
    String value = await TechlifyStorage.getString('key');
    print(value);
  }

  void logMessage() {
    TechlifyLogger.d('This is a debug message');
    TechlifyLogger.i('This is an info message');
    TechlifyLogger.w('This is a warning message');
    TechlifyLogger.e('This is an error message');
  }

  void getDeviceInfo() async {
    String deviceModel = await TechlifyDeviceInfo.getDeviceModel();
    String osVersion = await TechlifyDeviceInfo.getOsVersion();
    print('Device Model: $deviceModel, OS Version: $osVersion');
  }

  void requestPermission() async {
    bool granted = await TechlifyPermissions.request(Permission.camera);
    if (granted) {
      print('Camera permission granted');
    } else {
      print('Camera permission denied');
    }
  }
