Flutter滑动交互插件slide_tape的使用

Flutter滑动交互插件slide_tape的使用

安装

在你的 pubspec.yaml 文件中添加以下依赖:

dependencies:
  slide_tape: ^0.1.0

然后运行 flutter pub get 来安装该包。

使用

首先,确保你已经将 slide_tape 包添加到你的项目中。接下来,你可以使用 SlideTape 组件来创建一个滑动手势交互。

以下是 SlideTape 的基本用法示例:

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

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

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: HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  HomePage({Key? key}) : super(key: key);

  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Slide Tape'),
      ),
      body: Column(
        children: [
          SlideTape(
            slideDirection: SlideDirection.RIGHT,
            backgroundColor: Colors.white70,
            slidingBarColor: Colors.orange,
            iconArrow: true,
            slidingChild: Container(
              child: Row(
                children: [
                  Expanded(
                    child: Container(
                      margin: EdgeInsets.all(15),
                      child: Container(
                        margin: EdgeInsets.only(right: 60),
                        child: Text('Otros widgets aqui 👽'),
                      ),
                    ),
                  )
                ],
              ),
            ),
            height: 100,
          ),
          SlideTape(
            slideDirection: SlideDirection.LEFT,
            backgroundColor: Colors.white70,
            slidingBarColor: Colors.black,
            iconArrow: true,
            slidingChild: Container(
              child: Row(
                children: [
                  Expanded(
                    child: Container(
                      margin: EdgeInsets.all(15),
                      child: Container(
                        margin: EdgeInsets.only(right: 60),
                        child: Text(
                          'Otros widgets aqui 👽',
                          style: TextStyle(color: Colors.white),
                          textAlign: TextAlign.right,
                        ),
                      ),
                    ),
                  )
                ],
              ),
            ),
            height: 100,
          ),
        ],
      ),
    );
  }
}

代码解释

  1. 导入必要的库

    import 'package:flutter/material.dart';
    import 'package:slide_tape/slide_tape.dart';
    
  2. 定义主应用类

    void main() {
      runApp(const MyApp());
    }
    
    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: HomePage(),
        );
      }
    }
    
  3. 定义主页类

    class HomePage extends StatefulWidget {
      HomePage({Key? key}) : super(key: key);
    
      @override
      State<HomePage> createState() => _HomePageState();
    }
    
  4. 定义主页状态类

    class _HomePageState extends State<HomePage> {
      @override
      Widget build(BuildContext context) {
        return Scaffold(
          appBar: AppBar(
            title: Text('Slide Tape'),
          ),
          body: Column(
            children: [
              SlideTape(
                slideDirection: SlideDirection.RIGHT,
                backgroundColor: Colors.white70,
                slidingBarColor: Colors.orange,
                iconArrow: true,
                slidingChild: Container(
                  child: Row(
                    children: [
                      Expanded(
                        child: Container(
                          margin: EdgeInsets.all(15),
                          child: Container(
                            margin: EdgeInsets.only(right: 60),
                            child: Text('Otros widgets aqui 👽'),
                          ),
                        ),
                      )
                    ],
                  ),
                ),
                height: 100,
              ),
              SlideTape(
                slideDirection: SlideDirection.LEFT,
                backgroundColor: Colors.white70,
                slidingBarColor: Colors.black,
                iconArrow: true,
                slidingChild: Container(
                  child: Row(
                    children: [
                      Expanded(
                        child: Container(
                          margin: EdgeInsets.all(15),
                          child: Container(
                            margin: EdgeInsets.only(right: 60),
                            child: Text(
                              'Otros widgets aqui 👽',
                              style: TextStyle(color: Colors.white),
                              textAlign: TextAlign.right,
                            ),
                          ),

                      )
                    ],
                  ),
                ),
                height: 100,

slide_tape 是一个用于 Flutter 的滑动交互插件,通常用于创建类似滑动面板或滑动条的效果。虽然 slide_tape 并不是 Flutter 官方或最流行的插件,但它可以实现一些自定义的滑动交互效果。以下是一个基本的使用示例,假设你已经将 slide_tape 添加到你的 pubspec.yaml 文件中。

1. 添加依赖

首先,在你的 pubspec.yaml 文件中添加 slide_tape 依赖:

dependencies:
  flutter:
    sdk: flutter
  slide_tape: ^版本号  # 请替换为实际的版本号

然后运行 flutter pub get 来安装依赖。

2. 基本使用示例

以下是一个简单的 slide_tape 使用示例:

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

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

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: SlideTapeExample(),
    );
  }
}

class SlideTapeExample extends StatefulWidget {
  [@override](/user/override)
  _SlideTapeExampleState createState() => _SlideTapeExampleState();
}

class _SlideTapeExampleState extends State<SlideTapeExample> {
  double _value = 0.0;

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('SlideTape Example'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text('Current Value: ${_value.toStringAsFixed(2)}'),
            SizedBox(height: 20),
            SlideTape(
              min: 0.0,
              max: 100.0,
              value: _value,
              onChanged: (double value) {
                setState(() {
                  _value = value;
                });
              },
              tapeWidth: 200.0,
              tapeHeight: 50.0,
              thumbSize: 30.0,
            ),
          ],
        ),
      ),
    );
  }
}
