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。
