Working with ReorderableListViews in Flutter
ReorderableListViews are a powerful way to create lists inside your Flutter app that are reorderable. With this feature, you can create visually appealing and interactive list viewers with a few lines of code. The beauty of ReorderableListView is that you don’t need to write any extra logic for enabling users to rearrange the list items. We will discuss how to use ReorderableListViews in your Flutter apps and what features they offer.
What is a ReorderableListView?
A ReorderableListView is a widget that allows users to rearrange items in a list by dragging and dropping them. It is similar to a regular ListView, but it has the added functionality of allowing the user to reorder items in the list. This widget enables users to drag and drop items between positions, and also to delete items from the list if desired.
How to Use ReorderableListViews in Flutter?
Adding a ReorderableListView to your app is as easy as adding a normal ListView. All you need to do is set the “isReorderable” parameter in the constructor to true. Here’s an example of a simple ReorderableListView:
ReorderableListView(
children: <Widget>[
ListTile(
title: Text('Item 1'),
),
ListTile(
title: Text('Item 2'),
),
],
isReorderable: true,
)
The :isReorderable parameter is all you need to create a fully functional ReorderableListView. You can also use other optional parameters like header and footer to customize the look and feel of your list.
