Getting Started

• Add this to your pubspec.yaml

  dependencies:
  liquid_swipe: ^3.1.0
  
  

• Get the package from Pub:

  flutter packages get
  

• Import it in your file

  import 'package:liquid_swipe/liquid_swipe.dart';
  

Usage

• Liquid Swipe just requires the list of Widgets like Container. Just to provide flexibity to the developer to design its own UI through it.

final pages = [
   Container(...),
   Container(...),
   Container(...),
 ];

• Now just pass these pages to LiquidSwipe widget.

 @override
 Widget build(BuildContext context) {
   return new MaterialApp(
     home: Builder(
         builder: (context) =>
             LiquidSwipe(
                 pages: pages
             )),
   );
 }

• Check out the complete Example

Migration

Some things to keep in mind while updating to v2.0.0 from any version.

• v2.0.0 is migrated to null safety. See migration
• Attribute enableSlideIcon is removed from LiquidSwipe. You can simply pass null to slideIconWidget to enable and disable it.
• Attribute positionSlideIcon is now ranged from 0.0 to 1.0.
• Next Reveal is there by default. If you want to disable it you might want to make changes in your fork. Create an issue I will help.

That's it ;)

Sample APK

Please download apk from Releases or Assets folder

LiquidController

A Controller class with some utility fields and methods.

Simple Usage :

Firstly make an Object of LiquidController and initialize it in initState()

   LiquidController liquidController;

   @override
   void initState() {
   super.initState();
   liquidController = LiquidController();
   }

Now simply add it to LiquidSwipe's Constructor

   LiquidSwipe(
        pages: pages,
        LiquidController: liquidController,
    ),

Only Rules/Limitation to its Usage is, you can't use any method in Liquid Controller before build method is being called in which LiquidSwipe is initialized. So we have to use them after LiquidSwipe is Built

• Properties
  • currentPage - Getter to get current Page. Default value is 0.
  • isUserGestureDisabled - If somehow you want to check if gestures are disabled or not. Default value is false;
• Methods
  • animateToPage({required int page, int duration = 600}) Animate to mentioned page within given Duration Remember the duration here is the total duration in which it will animate though all pages not the single page.
  • jumpToPage({required int page}) Jump Directly to mentioned Page index but without Animation.
  • shouldDisableGestures({required bool disable}) Use this method to disable gestures during runtime, like on certain pages using OnPageChangeCallback.

Please Refer to API documentation for more details.
