slideable

Description:

slideable

Slideable #
This is a flexible slideable implementation that will allow you to pass simple widgets(icons or anything at all) as action items, and also control various backgrounds for the action item, and closes an already slide item in your list.
This is a side project that I have reused severally on lots of my project and decided to turn it into a package for anyone that wants more flexibility than the usual flutter_slidable package.
Features #


Control flexibility on the type of widget to use as your action item.


A predefined callback function that automatically closes an already slid item in your list.


Can contain a maximum of 6 action items.


You can control the animation curver and animation speed.


Getting started #
In the pubspec.yaml of you flutter project, add the following dependency:
dependencies:
slideable: <latest_version>

In your screen or page, add the below import, to expose the package:
import 'package:slideable/Slideable.dart';

Basic Usage #


ActionItems, controls the actions widget you would want to have in the display. This is a List<ActionItems>, where, each actionItem consists of the required icon widget, which can be any accepted Flutter Widget, a required onPress function, that executes what you want that ActionItem to do, a defaulted backgroundColor of transparent, which is totally flexible to change and a radius, just incase you want to add a tweak to your design to match the Slidable child's borderRadius.
ActionItems(
icon: const Icon(
Icons.thumb_up,
color: Colors.blue,
),
onPress: () {},
backgroudColor: Colors.transparent,
),

Slideable, requires the ActionItems item widget list and the child, which will be the initial point of contact in our case.
The other values includes the backgroundColor, which by default is set to transparent' but can be changed to suit your design. resetSlide, which is a boolean value used to notifiy the Slideable to close all the slid item, unless set to false by an external false. A duration, which is used to control the the slide time and the curve, which is used to control the speed or motion of the slide animation.
// This is used to monitor the item index in the list, and later used to closeup or leave open the slide.

int resetSlideIndex = 0;
