Flutter Slidable ListView Action on ListTiles
Flutter Slidable ListView Action on ListTiles

Hi Guys, Welcome to Proto Coders Point In this Flutter Tutorial we will implement Flutter Slidable action on ListView with ListTile widget.

Flutter Slidable Widget

A Flutter Slidable Widget can be applied on Flutter ListView with ListTile widget that can help developer to give left or right directional slide actions with we create a beautiful User Interface and User Experience where user this Slidable widget to dismiss any listTile he don’t want to user.

Eg: you might have used gmail mobile app which makes user of Slidable listTile where you can easily slide left or right on the email you recieved where you can take different actions like delete the mail, or mark it as important and many more actions

let’s begin implementing Flutter Slidable in our project

Adding this package in our project

To add this slidable package into our project you need to

Add this to your package’s pubspec.yaml file:

dependencies:
  flutter_slidable: ^0.5.4  // version might vary

Note : the verison might vary by time so just go to official site to get latest version of this library.

once you add the dependencies in pubspec.yaml file just click on Packages get, and then required package is been added into our flutter project.

Importing package

As you added the dependencies all the required packages will be added to your project.

All you need to do is just import the package dart file where every it’s requited.

import 'package:flutter_slidable/flutter_slidable.dart';

Snippet code of Flutter Slidable

Slidable(
  actionPane: SlidableDrawerActionPane(),
  actionExtentRatio: 0.25,
  child: Container(
    color: Colors.white,
    child: ListTile(
      leading: CircleAvatar(
        backgroundColor: Colors.indigoAccent,
        child: Text('$3'),
        foregroundColor: Colors.white,
      ),
      title: Text('Tile n°$3'),
      subtitle: Text('SlidableDrawerDelegate'),
    ),
  ),
  actions: <Widget>[
    IconSlideAction(
      caption: 'Archive',
      color: Colors.blue,
      icon: Icons.archive,
      onTap: () => _showSnackBar('Archive'),
    ),
    IconSlideAction(
      caption: 'Share',
      color: Colors.indigo,
      icon: Icons.share,
      onTap: () => _showSnackBar('Share'),
    ),
  ],
  secondaryActions: <Widget>[
    IconSlideAction(
      caption: 'More',
      color: Colors.black45,
      icon: Icons.more_horiz,
      onTap: () => _showSnackBar('More'),
    ),
    IconSlideAction(
      caption: 'Delete',
      color: Colors.red,
      icon: Icons.delete,
      onTap: () => _showSnackBar('Delete'),
    ),
  ],
);

Built-in slide actions

This package comes with 2 kinds of slide actions:

  • SlideAction, which is the most flexible. You can choose a background color, or any decoration, and it takes any widget as a child.
  • IconSlideAction, which requires an icon. It can have a background color and a caption below the icon.

In this Flutter Tutorial we are making use of IconSlideAction, so that we can easily add some icons with background color and some caption to it.

Built-in action panes

Action panes is required  to add the slidable listView ListTile

This package comes with 4 kinds of action panes:

  • SlidableBehindActionPane : The slide actions stay behind the item while it’s sliding
  • SlidableScrollActionPane : The slide actions follow the item while it’s sliding
  • SlidableDrawerActionPane : The slide actions animate like drawers while the item is sliding
  • SlidableStrechActionPane : The slide actions stretch while the item is sliding

Complete Code on Flutter Slidable with ListView.builder  with ListTile

In the Below Code i have created a list of Strings that range from 0 – 9 (i.e 10 list items)

final List<String> items =
        new List<String>.generate(10, (i) => "item  ${i + 1}");

Then, In the body part we have ListView Builder that simple returns Slidable widget.

This Sliable widget have  4 other properties those are:

actionPane : This is mandatory to be included there are 4 build-In actionPane ( check out able )

actionPane: SlidableDrawerActionPane()

action :  This is primary action that show when listView is slided from left side.

actions: <Widget>[
  IconSlideAction(
    icon: Icons.more,
    caption: 'MORE',
    color: Colors.blue,
  ),
],

secondaryAction : As the slidable property say it an secondary action that show when  listView is slided from right side.

Finally, the child : which can be any widget, in this flutter slidable tutorial i have added ListTile as a child.

Below is the Complete Code base just copy paste it in main.dart file
