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 Transform
和 BoxShadow
实现 3D 按钮
你可以使用 Flutter 的 Transform
和 BoxShadow
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!');
},
),
),
),
));
}
