flutter 中使用flutter_slidable 实现左滑显示删除、修改菜单，仿微信

本文主要是介绍flutter 中使用flutter_slidable 实现左滑显示删除、修改菜单，仿微信，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

flutter pub add flutter_slidable

导入

import 'package:flutter_slidable/flutter_slidable.dart';

使用

import 'package:flutter/material.dart';
import 'package:flutter_slidable/flutter_slidable.dart';void main() => runApp(const MyApp());class MyApp extends StatelessWidget {const MyApp({Key? key,}) : super(key: key);@overrideWidget build(BuildContext context) {return MaterialApp(title: 'Slidable Example',home: Scaffold(body: ListView(children: [Slidable(// Specify a key if the Slidable is dismissible.key: const ValueKey(0),// The start action pane is the one at the left or the top side.startActionPane: ActionPane(// A motion is a widget used to control how the pane animates.motion: const ScrollMotion(),// A pane can dismiss the Slidable.dismissible: DismissiblePane(onDismissed: () {}),// All actions are defined in the children parameter.children: const [// A SlidableAction can have an icon and/or a label.SlidableAction(onPressed: doNothing,backgroundColor: Color(0xFFFE4A49),foregroundColor: Colors.white,icon: Icons.delete,label: 'Delete',),SlidableAction(onPressed: doNothing,backgroundColor: Color(0xFF21B7CA),foregroundColor: Colors.white,icon: Icons.share,label: 'Share',),],),// The end action pane is the one at the right or the bottom side.endActionPane: const ActionPane(motion: ScrollMotion(),children: [SlidableAction(// An action can be bigger than the others.flex: 2,onPressed: doNothing,backgroundColor: Color(0xFF7BC043),foregroundColor: Colors.white,icon: Icons.archive,label: 'Archive',),SlidableAction(onPressed: doNothing,backgroundColor: Color(0xFF0392CF),foregroundColor: Colors.white,icon: Icons.save,label: 'Save',),],),// The child of the Slidable is what the user sees when the// component is not dragged.child: const ListTile(title: Text('Slide me')),),Slidable(// Specify a key if the Slidable is dismissible.key: const ValueKey(1),// The start action pane is the one at the left or the top side.startActionPane: const ActionPane(// A motion is a widget used to control how the pane animates.motion: ScrollMotion(),// All actions are defined in the children parameter.children: [// A SlidableAction can have an icon and/or a label.SlidableAction(onPressed: doNothing,backgroundColor: Color(0xFFFE4A49),foregroundColor: Colors.white,icon: Icons.delete,label: 'Delete',),SlidableAction(onPressed: doNothing,backgroundColor: Color(0xFF21B7CA),foregroundColor: Colors.white,icon: Icons.share,label: 'Share',),],),// The end action pane is the one at the right or the bottom side.endActionPane: ActionPane(motion: const ScrollMotion(),dismissible: DismissiblePane(onDismissed: () {}),children: const [SlidableAction(// An action can be bigger than the others.flex: 2,onPressed: doNothing,backgroundColor: Color(0xFF7BC043),foregroundColor: Colors.white,icon: Icons.archive,label: 'Archive',),SlidableAction(onPressed: doNothing,backgroundColor: Color(0xFF0392CF),foregroundColor: Colors.white,icon: Icons.save,label: 'Save',),],),// The child of the Slidable is what the user sees when the// component is not dragged.child: const ListTile(title: Text('Slide me')),),],),),);}
}void doNothing(BuildContext context) {}

ActionPane的参数说明

ActionPane(key: Key(UniqueKey().toString()),extentRatio:0.2,// 滑动动效// DrawerMotion() StretchMotion()// motion: ScrollMotion(),motion: BehindMotion(),children: const [// SlidableAction(//   // An action can be bigger than the others.//   flex: 2,//   onPressed: doNothing,//   backgroundColor: Color(0xFF7BC043),//   foregroundColor: Colors.white,//   icon: Icons.archive,//   label: 'Archive',// ),SlidableAction(onPressed: doNothing,backgroundColor: Color(0xFF0392CF),foregroundColor: Colors.white,icon: Icons.save,label: 'Save',),],),

实现只有同时只有一个滑块

SlidableAutoCloseBehavior 包住listview部分代码就可以

          body:SlidableAutoCloseBehavior(child: ListView.builder(controller: _scrollController,//需要controller ,不然异常itemCount: datas.length,key: Key(UniqueKey().toString()),itemBuilder: (BuildContext context, int index) { return Slidable(// 禁用滑动enabled:true,dragStartBehavior:DragStartBehavior.start,// key:  ValueKey(index), // 设置只能有一个滑块key: Key(UniqueKey().toString()),// 右滑滑动显示的菜单// startActionPane: ActionPane(//   key: Key(UniqueKey().toString()),//   // A motion is a widget used to control how the pane animates.//   motion: const ScrollMotion(),//   // A pane can dismiss the Slidable.//   dismissible: DismissiblePane(onDismissed: () {//     print("点击了");//   }),//   // All actions are defined in the children parameter.//   children: const [//     // A SlidableAction can have an icon and/or a label.//     SlidableAction(//       onPressed: doNothing,//       backgroundColor: Color(0xFFFE4A49),//       foregroundColor: Colors.white,//       icon: Icons.delete,//       label: 'Delete',//     ),//     SlidableAction(//       onPressed: doNothing,//       backgroundColor: Color(0xFF21B7CA),//       foregroundColor: Colors.white,//       icon: Icons.share,//       label: 'Share',//     ),//   ],// ),//左滑划出的菜单endActionPane:  ActionPane(key: Key(UniqueKey().toString()),// 菜单宽度extentRatio:0.2,dragDismissible:false,// 滑动动效// DrawerMotion() StretchMotion()// motion: ScrollMotion(),motion: BehindMotion(),children: const [// SlidableAction(//   // An action can be bigger than the others.//   flex: 2,//   onPressed: doNothing,//   backgroundColor: Color(0xFF7BC043),//   foregroundColor: Colors.white,//   icon: Icons.archive,//   label: 'Archive',// ),SlidableAction(onPressed: doNothing,backgroundColor: Color(0xFF0392CF),foregroundColor: Colors.white,icon: Icons.save,label: 'Save',),],),child: ListTile(title: Text('Slide me')),);},),)
