当然,以下是如何在Flutter项目中使用smart_flutter_utils插件的一些代码示例。smart_flutter_utils是一个包含多种实用功能的Flutter插件,可以帮助开发者简化开发过程。

首先,你需要在你的pubspec.yaml文件中添加这个依赖:

dependencies:
  flutter:
    sdk: flutter
  smart_flutter_utils: ^latest_version  # 请替换为实际的最新版本号

然后运行flutter pub get来安装依赖。

以下是一些常用功能的代码示例:

1. 屏幕工具类

用于获取屏幕宽度、高度等信息的工具类。

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Screen Utils Example'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              Text('Screen Width: ${ScreenUtil().getScreenWidth()}'),
              Text('Screen Height: ${ScreenUtil().getScreenHeight()}'),
              Text('Screen Scale: ${ScreenUtil().getScreenScale()}'),
            ],
          ),
        ),
      ),
    );
  }
}

2. 加密解密工具类

用于基本的加密解密操作。

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    String originalString = "Hello, Flutter!";
    String encryptedString = EncryptUtil().md5(originalString);

    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Encrypt Decrypt Example'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              Text('Original String: $originalString'),
              Text('Encrypted String (MD5): $encryptedString'),
            ],
          ),
        ),
      ),
    );
  }
}

3. 日期时间工具类

用于处理日期时间的格式化等操作。

import 'package:flutter/material.dart';
import 'package:smart_flutter_utils/smart_flutter_utils.dart';
import 'package:intl/intl.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    DateTime now = DateTime.now();
    String formattedDate = DateFormat('yyyy-MM-dd HH:mm:ss').format(now);
    String formattedTimestamp = DateUtil().formatTimestamp(now.millisecondsSinceEpoch);

    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Date Time Utils Example'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              Text('Current Date Time: $formattedDate'),
              Text('Formatted Timestamp: $formattedTimestamp'),
            ],
          ),
        ),
      ),
    );
  }
}

4. 网络工具类

用于发送HTTP请求。

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

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

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String responseData = "";

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

  void _fetchData() async {
    String url = "https://jsonplaceholder.typicode.com/posts/1";
    String response = await NetworkUtil().get(url);
    setState(() {
      responseData = response;
    });
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Network Utils Example'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              Text('Response Data:'),
              Text(responseData),
            ],
          ),
        ),
      ),
    );
  }
}

这些示例展示了如何使用smart_flutter_utils插件中的屏幕工具类、加密解密工具类、日期时间工具类以及网络工具类。你可以根据自己的需求进行更多的自定义和扩展。
