  2. 圆形按钮（带有或不带强调色）
  3. 强调色列表（类似列表小部件）
  4. 指示器按钮
  5. 复选框
  6. 文本输入框

当然，下面是一个关于如何使用 itwillrock_neumorphism 插件的 Flutter 代码示例。itwillrock_neumorphism 是一个用于实现新拟物化设计（Neumorphism）效果的 Flutter 插件。它允许你轻松地为你的应用添加内阴影和外阴影，以创建立体和深度感。

首先，确保你已经在 pubspec.yaml 文件中添加了依赖项：

dependencies:
  flutter:
    sdk: flutter
  itwillrock_neumorphism: ^x.y.z  # 请使用最新版本号

然后，运行 flutter pub get 来获取依赖项。

以下是一个完整的 Flutter 应用示例，展示了如何使用 itwillrock_neumorphism 插件：

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

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Neumorphism Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: NeumorphismDemo(),
    );
  }
}

class NeumorphismDemo extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Neumorphism Demo'),
      ),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            NeumorphicButton(
              onPressed: () {
                print('Button pressed!');
              },
              child: Text('Neumorphic Button'),
              style: NeumorphicStyle(
                color: Colors.grey[300]!,
                shadowDarkColor: Colors.black.withOpacity(0.2),
                shadowLightColor: Colors.white.withOpacity(0.2),
                depth: 8,
                shape: NeumorphicShape.convex,
              ),
            ),
            SizedBox(height: 20),
            NeumorphicCard(
              child: Column(
                children: <Widget>[
                  Text('Neumorphic Card'),
                  SizedBox(height: 10),
                  NeumorphicButton(
                    onPressed: () {
                      print('Card Button pressed!');
                    },
                    child: Text('Inner Button'),
                    style: NeumorphicStyle(
                      color: Colors.grey[400]!,
                      shadowDarkColor: Colors.black.withOpacity(0.3),
                      shadowLightColor: Colors.white.withOpacity(0.3),
                      depth: 6,
                      shape: NeumorphicShape.convex,
                    ),
                  ),
                ],
              ),
              margin: EdgeInsets.all(16),
              style: NeumorphicStyle(
                color: Colors.grey[200]!,
                shadowDarkColor: Colors.black.withOpacity(0.1),
                shadowLightColor: Colors.white.withOpacity(0.1),
                depth: 4,
                shape: NeumorphicShape.roundRect(borderRadius: BorderRadius.circular(16)),
              ),
            ),
          ],
        ),
      ),
    );
  }
}

解释

  1. 依赖项：确保在 pubspec.yaml 中添加 itwillrock_neumorphism 依赖项。

  2. NeumorphicButton：这是一个带有内阴影和外阴影的按钮，可以创建立体效果。通过 NeumorphicStyle，你可以自定义按钮的颜色、阴影颜色、深度和形状。

  3. NeumorphicCard：这是一个带有内阴影和外阴影的卡片，可以包含其他子组件。同样，通过 NeumorphicStyle，你可以自定义卡片的样式。

  4. NeumorphicStyle：这个类用于定义阴影颜色、深度、形状等参数，以创建不同的新拟物化效果。

运行上述代码，你将看到一个包含两个按钮的示例应用，一个单独的 NeumorphicButton 和一个包含 NeumorphicButton 的 NeumorphicCard。每个组件都应用了不同的新拟物化样式，以展示插件的灵活性。
