Flutter 3D按钮效果插件flutter_button_three_d的使用

Flutter 3D按钮效果插件flutter_button_three_d的使用

在Flutter开发中,有时我们需要为应用程序添加一些具有立体感的按钮效果,以提升用户体验。flutter_button_three_d 是一个非常方便的插件,用于实现类似3D按钮的效果。

使用步骤

1. 添加依赖

首先,在 pubspec.yaml 文件中添加 flutter_button_three_d 作为依赖:

dependencies:
  flutter_button_three_d: ^1.0.0

然后运行以下命令来获取依赖:

flutter pub get

2. 导入库并创建按钮

接下来,我们将在示例代码中展示如何使用 flutter_button_three_d 插件来创建一个带有3D效果的按钮。

示例代码

import 'package:flutter/material.dart';
import 'package:flutter_button_three_d/flutter_button.dart'; // 引入插件

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

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

  [@override](/user/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 3D Button Example'),
    );
  }
}

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

  final String title;

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

class _MyHomePageState extends State<MyHomePage> {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: const Center(
        // 使用 FlutterTextButton3D 创建3D按钮
        child: FlutterTextButton3D(
          enableAnimation: true, // 开启动画效果
          text: Text("点击我"), // 按钮上的文字
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () {},
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ),
    );
  }
}

flutter_button_three_d 是一个用于在 Flutter 应用中创建 3D 按钮效果的插件。虽然目前(截至 2023 年)没有一个官方的插件名为 flutter_button_three_d,但你可以使用一些已有的库或自定义代码来实现类似的效果。

以下是一个使用 Flutter 内置功能和自定义代码来实现 3D 按钮效果的示例:

1. 使用 TransformBoxShadow 实现 3D 按钮

你可以使用 Flutter 的 TransformBoxShadow 来创建一个简单的 3D 按钮效果。

import 'package:flutter/material.dart';

class ThreeDButton extends StatelessWidget {
  final String text;
  final VoidCallback onPressed;

  const ThreeDButton({Key? key, required this.text, required this.onPressed}) : super(key: key);

  [@override](/user/override)
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: onPressed,
      child: Transform(
        transform: Matrix4.identity()..translate(0.0, 0.0, 0.0),
        child: Container(
          padding: EdgeInsets.symmetric(vertical: 12.0, horizontal: 24.0),
          decoration: BoxDecoration(
            color: Colors.blue,
            borderRadius: BorderRadius.circular(8.0),
            boxShadow: [
              BoxShadow(
                color: Colors.blue.shade700,
                offset: Offset(0, 5),
                blurRadius: 0,
                spreadRadius: 0,
              ),
            ],
          ),
          child: Center(
            child: Text(
              text,
              style: TextStyle(
                color: Colors.white,
                fontSize: 18.0,
                fontWeight: FontWeight.bold,
              ),
            ),
          ),
        ),
      ),
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: Scaffold(
      appBar: AppBar(title: Text('3D Button Example')),
      body: Center(
        child: ThreeDButton(
          text: 'Press Me',
          onPressed: () {
            print('Button Pressed!');
          },
        ),
      ),
    ),
  ));
}

2. 使用 AnimatedContainer 实现点击效果

你还可以使用 AnimatedContainer 来实现按钮点击时的动画效果。

import 'package:flutter/material.dart';

class ThreeDButton extends StatefulWidget {
  final String text;
  final VoidCallback onPressed;

  const ThreeDButton({Key? key, required this.text, required this.onPressed}) : super(key: key);

  [@override](/user/override)
  _ThreeDButtonState createState() => _ThreeDButtonState();
}

class _ThreeDButtonState extends State<ThreeDButton> {
  bool _isPressed = false;

  [@override](/user/override)
  Widget build(BuildContext context) {
    return GestureDetector(
      onTapDown: (_) => setState(() => _isPressed = true),
      onTapUp: (_) => setState(() => _isPressed = false),
      onTapCancel: () => setState(() => _isPressed = false),
      onTap: widget.onPressed,
      child: AnimatedContainer(
        duration: Duration(milliseconds: 100),
        padding: EdgeInsets.symmetric(vertical: 12.0, horizontal: 24.0),
        decoration: BoxDecoration(
          color: Colors.blue,
          borderRadius: BorderRadius.circular(8.0),
          boxShadow: _isPressed
              ? []
              : [
                  BoxShadow(
                    color: Colors.blue.shade700,
                    offset: Offset(0, 5),
                    blurRadius: 0,
                    spreadRadius: 0,
                  ),
                ],
        ),
        child: Center(
          child: Text(
            widget.text,
            style: TextStyle(
              color: Colors.white,
              fontSize: 18.0,
              fontWeight: FontWeight.bold,
            ),
          ),
        ),
      ),
    );
  }
}

void main() {
  runApp(MaterialApp(
    home: Scaffold(
      appBar: AppBar(title: Text('3D Button Example')),
      body: Center(
        child: ThreeDButton(
          text: 'Press Me',
          onPressed: () {
            print('Button Pressed!');
          },
        ),
      ),
    ),
  ));
}
