Flutter未知功能插件flemme的潜在使用

Flemme 插件介绍

Flemme 是一个用于简化 Flutter 开发中编写自定义控件的插件。它提供了一些实用的功能，如自定义 Padding、生成模态框等。通过使用 Flemme，开发者可以更方便地创建和配置各种控件。

安装插件

首先，在 pubspec.yaml 文件中添加依赖项：

dependencies:
  flemme: ^0.0.13

示例代码

下面是一个完整的示例代码，展示了如何使用 Flemme 插件来简化控件的创建和配置。

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

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  // This widget is the root of your application.
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flemme Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Flemme Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);

  final String title;

  [@override](/user/override)
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      // This call to setState tells the Flutter framework that something has
      // changed in this State, which causes it to rerun the build method below
      // so that the display can reflect the updated values. If we changed
      // _counter without calling setState(), then the build method would not be
      // called again, and so nothing would appear to happen.
      _counter++;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return flemmeScaffoldExample();
  }

  Scaffold defaultFlutterScaffoldExample() {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            const Text(
              'You have pushed the button this many times:',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headlineMedium,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ), // This trailing comma makes auto-formatting nicer for build methods.
    );
  }

  Scaffold flemmeScaffoldExample() {
    FlemmeConfig().paddingAllM = const EdgeInsets.all(100); // 设置默认 padding
    return Scaffold(
      appBar: AppBar(
        title: widget.title.toTextWidget(),
      ),
      body: [
        'You have pushed the button this many times:'.toTextWidget().withPadding(),
        '$_counter'.toTextWidget(style: Theme.of(context).textTheme.headlineMedium),
      ].listToColumn(mainAxisAlignment: MainAxisAlignment.center).withCenter(),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ), // This trailing comma makes auto-formatting nicer for build methods.
    );
  }
}
