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')),);},),)
