flutter_card_swiper #

flutter_card_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
  • choose our own settings for the swiper such as duration, angle, padding..
  • NEW: trigger swipe, swipe left and swipe right however we want
  • NEW: add functions while un-/swiping, on end or when the swiper is disabled
  • NEW: detect the direction (left, right, top, bottom) in which the card was swiped away

Detect direction of swipe #

We've added the direction in which the card was swiped away to the function onSwipe. The AppinioSwipeDirection gets now returned when the function gets called.

Trigger swipe through controller #

You can now trigger the swipe with our CardSwiperController. You can call the swipe trough the controller anywhere you want. Just make sure to pass the controller to the parameter controller from our CardSwiper.

Show Cases #

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

Customize the angle...

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

Installation #

For help getting started with Flutter, view the online documentation.

Usage #

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

card_swiperimport 'package:flutter_card_swiper/card_swiper.dart';
import 'package:flutter/cupertino.dart';

class Example extends StatelessWidget {
  List<Container> cards = [
    Container(
      alignment: Alignment.center,
      child: const Text('1'),
      color: CupertinoColors.activeBlue,
    ),
    Container(
      alignment: Alignment.center,
      child: const Text('2'),
      color: CupertinoColors.activeBlue,
    ),
    Container(
      alignment: Alignment.center,
      child: const Text('3'),
      color: CupertinoColors.activeBlue,
    )
  ];

  @override
  Widget build(BuildContext context) {
    return CupertinoPageScaffold(
      child: SizedBox(
        height: MediaQuery.of(context).size.height * 0.75,
        child: CardSwiper(
          cards: cards,
        ),
      ),
    );
  }
}

Controller

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