appinio_swiper 2.0.3

An awesome fully custamisable Tinder Card Swiper which allows swiping in all directions with any Custom Widget (Stateless or Statefull).

appinio_swiper is a Flutter package for a Tinder Card Swiper. ✨

It allows swiping in all directions with any Custom Widget (Stateless or Statefull).

Very smooth animations supporting Android, iOS & WebApp.

Why?

We build this package because we wanted to:

• have a complete customizable slider
• be able to swipe in every direction
• trigger unswipe however we want
• choose our own settings for the swiper such as duration, angle, padding..
• trigger swipe, swipe left/right or swipe up/down however we want
• set swipe options and restrict horizontal or vertical swipe.
• set loop for infinite scroll
• update the list of cards between swipes.
• Check in which direction the card is being swiped and modify your widget accordingly.
• NEW - We can have any number of background cards.
• NEW - Pass any combination of swipe options.

❗NEW Features ❗

Space background cards as per your requirement.

Now you can decide the spacing between the background cards and can also hide them by giving cardsSpacing = 0.

onSwipeCancelEvent.

We have added onSwipeCancel event to check if the card swiped completely or if the swipe got canceled in the middle.

Add different combinations for swipe options.

Now you can provide any combination of swipe options. For example: The user can swipe to the left and bottom but not top, or any possible combination.

Show any number of background cards.

Now you can decide how many background cards you want to show.

Listen to card swipes

Now you can check in which direction the card is being swiped and modify your widget accordingly

Trigger swipe up and swipe down through controller

You can now trigger swipe up and swipe down with our AppinioSwiperController regardless of the chosen AppinioSwipeDirection (which is still used when swipe is called through the controller). Just like the swipeLeft and swipeRight call, you can call swipeUp or swipeDown through the controller anywhere you want.

Restrict horizontal or vertical swipe

You can now restrict the swipe in either horizontal directions or vertical directions using swipeOptions property.

Set looping for card swipe

Now you can set the loop property to true and make the list infinitely scrollable.

Update the cards while swiping

In this version we have replaced the list of cards with cardsBuilder. Now the widget only renders two cards at a time which makes it lightweight and scalable. So you can perform operations on your card anytime.

Show Cases

Trigger swipe right and swipe left however you want...

Unswipe the cards however you want...

Customize the angle...

Customize the threshold of the swiper, when the card should slide away...

Installation

Create a new project with the command

flutter create MyApp

Add

appinio_swiper: ...

Usage

You can place your AppinioSwiper inside of a Scaffold or CupertinoPageScaffold like we did here. Optional parameters can be defined to enable different features. See the following example..

import 'package:appinio_swiper/appinio_swiper.dart';
import 'package:flutter/cupertino.dart';

class Example extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return CupertinoPageScaffold(
      child: SizedBox(
        height: MediaQuery.of(context).size.height * 0.75,
        child: AppinioSwiper(
          cardsCount: 10,
          onSwiping: (AppinioSwiperDirection direction){
            print(direction.toString());
          },
          cardsBuilder: (BuildContext context,int index){
              return Container(
                          alignment: Alignment.center,
                          child: const Text(index.toString()),
                          color: CupertinoColors.activeBlue,
                          );
          },
        ),
      ),
    );
  }
}

Controller

The Controller is used to control the swipe, swipeLeft, swipeRight, swipeUp, swipeDown or unswipe function of the swiper from outside of the widget. You can create a controller called AppinioSwiperController and save the instance for further usage. Please have a closer look to our Example for the usage.

swipeUp	Changes the state of the controller to swipe up and swipes the card to the up side.
