Flutter仿拟物风格UI插件custom_neumorphic的使用

Custom Neumorphic Flutter Package.

示例代码

以下是一个完整的示例，展示了如何在Flutter应用中使用custom_neumorphic插件。

import 'package:flutter/material.dart';
import 'package:custom_neumorphic/custom_neumorphic.dart'; // 导入custom_neumorphic包

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // 这个小部件是你的应用的根。
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

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

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

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

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            const Text(
              '你已经按下了按钮次数：',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headlineMedium,
            ),
            CustomNeumorphic( // 使用CustomNeumorphic小部件
              padding: EdgeInsets.all(20),
              neumorphicShape: NeumorphicShape.concave,
              boxShape: NeumorphicBoxShape.roundRect(BorderRadius.circular(10)),
              depth: 8,
              accentColor: Colors.grey,
              lightSource: LightSource.topLeft,
              child: Container(
                width: 200,
                height: 200,
                color: Colors.white,
                child: Center(
                  child: Text('Neumorphic Box'),
                ),
              ),
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: '增加',
        child: const Icon(Icons.add),
      ),
    );
  }
}

代码解释

1. 导入包：

   import 'package:custom_neumorphic/custom_neumorphic.dart';
   

   首先导入custom_neumorphic包。

2. 主应用类：

   class MyApp extends StatelessWidget {
     const MyApp({super.key});
     
     @override
     Widget build(BuildContext context) {
       return MaterialApp(
         title: 'Flutter Demo',
         theme: ThemeData(
           colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
           useMaterial3: true,
         ),
         home: const MyHomePage(title: 'Flutter Demo Home Page'),
       );
     }
   }
   

   定义了应用的基本结构和主题。

3. 主页面类：

   class MyHomePage extends StatefulWidget {
     const MyHomePage({super.key, required this.title});
     
     final String title;
     
     @override
     State<MyHomePage> createState() => _MyHomePageState();
   }
   

   主页面定义了一个状态管理类_MyHomePageState。

4. 状态管理类：

   class _MyHomePageState extends State<MyHomePage> {
     int _counter = 0;
     
     void _incrementCounter() {
       setState(() {
         _counter++;
       });
     }
     
     @override
     Widget build(BuildContext context) {
       return Scaffold(
         appBar: AppBar(
           backgroundColor: Theme.of(context).colorScheme.inversePrimary,
           title: Text(widget.title),
         ),
         body: Center(
           child: Column(
             mainAxisAlignment: MainAxisAlignment.center,
             children: [
               const Text(
                 '你已经按下了按钮次数：',
               ),
               Text(
                 '$_counter',
                 style: Theme.of(context).textTheme.headlineMedium,
               ),
               CustomNeumorphic(
                 padding: EdgeInsets.all(20),
                 neumorphicShape: NeumorphicShape.concave,
                 boxShape: NeumorphicBoxShape.roundRect(BorderRadius.circular(10)),
                 depth: 8,
                 accentColor: Colors.grey,
                 lightSource: LightSource.topLeft,
                 child: Container(
                   width: 200,
                   height: 200,
                   color: Colors.white,
                   child: Center(
                     child: Text('Neumorphic Box'),
                   ),
                 ),
               ),
             ],
           ),
         ),
         floatingActionButton: FloatingActionButton(
           onPressed: _incrementCounter,
           tooltip: '增加',
           child: const Icon(Icons.add),
         ),
       );
     }
   }
