Flutter实用工具集合插件fluttils的使用

当然，fluttils 是一个集合了多种实用工具的 Flutter 插件，它可以帮助开发者在开发过程中快速实现一些常见的功能。以下是一些关于如何使用 fluttils 插件的代码案例。

首先，确保你的 Flutter 项目已经添加了 fluttils 依赖。在 pubspec.yaml 文件中添加以下依赖：

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

然后运行 flutter pub get 来安装依赖。

1. 使用 Fluttils.deviceUtils 获取设备信息

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Fluttils Demo'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              Text('Device Brand: ${Fluttils.deviceUtils?.brand}'),
              Text('Device Model: ${Fluttils.deviceUtils?.model}'),
              Text('Screen Width: ${Fluttils.screenUtils?.screenWidth}'),
              Text('Screen Height: ${Fluttils.screenUtils?.screenHeight}'),
            ],
          ),
        ),
      ),
    );
  }
}

2. 使用 Fluttils.networkUtils 进行网络请求

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

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

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Fluttils Network Demo'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              ElevatedButton(
                onPressed: () async {
                  String url = 'https://api.example.com/data'; // 替换为实际的API URL
                  var response = await Fluttils.networkUtils?.get(url);
                  setState(() {
                    responseData = response?.body ?? 'Error fetching data';
                  });
                },
                child: Text('Fetch Data'),
              ),
              Text('Response: $responseData'),
            ],
          ),
        ),
      ),
    );
  }
}

3. 使用 Fluttils.imageUtils 进行图片处理

import 'package:flutter/material.dart';
import 'package:fluttils/fluttils.dart';
import 'dart:ui' as ui;

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

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

class _MyAppState extends State<MyApp> {
  ImageProvider imageProvider;

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

  void loadImage() async {
    var imageBytes = await Fluttils.imageUtils?.getAssetImageBytes('assets/images/sample.png'); // 替换为实际的图片路径
    ui.Codec codec = await ui.instantiateImageCodec(imageBytes!);
    FrameInfo frameInfo = await codec.getNextFrame();
    imageProvider = frameInfo.image;
    setState(() {});
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Fluttils Image Demo'),
        ),
        body: Center(
          child: imageProvider != null ? Image(image: imageProvider!) : CircularProgressIndicator(),
        ),
      ),
    );
  }
}

4. 使用 Fluttils.stringUtils 进行字符串处理

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    String originalString = "Hello, Flutter!";
    String capitalizedString = Fluttils.stringUtils?.capitalize(originalString) ?? originalString;
    String reversedString = Fluttils.stringUtils?.reverse(originalString) ?? originalString;

    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Fluttils String Demo'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              Text('Original String: $originalString'),
              Text('Capitalized String: $capitalizedString'),
              Text('Reversed String: $reversedString'),
            ],
          ),
        ),
      ),
    );
  }
}

以上代码展示了如何使用 fluttils 插件中的一些实用工具，包括获取设备信息、进行网络请求、处理图片以及处理字符串。你可以根据项目需求进一步扩展这些功能。
