Sample Code Using flutter_card_swiper:

The following code demonstrates how to use the flutter_card_swiper package to implement a Tinder-like card swiping feature in a Flutter dating app.

CardSwiper(cardBuilder: (context, index, horizontalOffsetPercentage, verticalOffsetPercentage) {
                 DatingProfile profile = profiles[index];
                 
                 return Container(
                   
                    child: Column(crossAxisAlignment: CrossAxisAlignment.start,
                      children: [
                        Expanded(
  child: Container(
    width: double.infinity,
    decoration: BoxDecoration(
      image: DecorationImage(
        fit: BoxFit.cover,
        image: NetworkImage(
          profile.imageUrls.isNotEmpty?profile.imageUrls[0]:"https://i.pinimg.com/736x/12/d6/94/12d694f54fa6c8ddaf26a193c858de0c.jpg",
        ),
      ),
    ),
    child: Stack(
      children: [
        // Gradient overlay at the bottom
        Align(
          alignment: Alignment.bottomCenter,
          child: Container(
            height: 100, // Adjust as needed
            decoration: BoxDecoration(
              gradient: LinearGradient(
                begin: Alignment.topCenter,
                end: Alignment.bottomCenter,
                colors: [
                  Colors.transparent,
                  Colors.black.withOpacity(0.7),
                ],
              ),
            ),
          ),
        ),
        // Name & Age Text
        Align(
          alignment: Alignment.bottomLeft,
          child: Padding(
            padding: const EdgeInsets.symmetric(horizontal: 12, vertical: 20),
            child: Container(
              padding: EdgeInsets.symmetric(horizontal: 10, vertical: 5),
              decoration: BoxDecoration(
                color: Colors.black.withOpacity(0.5), // Semi-transparent background
                borderRadius: BorderRadius.circular(10),
              ),
              child: Text(
                "${profile.name}, ${profile.age}",
                style: TextStyle(
                  color: ColorPalette.white,
                  fontSize: 25,
                  fontWeight: FontWeight.bold,
                  shadows: [
                    Shadow(
                      offset: Offset(0, 2),
                      blurRadius: 6.0,
                      color: Colors.black.withOpacity(0.8),
                    ),
                  ],
                ),
              ),
            ),
          ),
        ),
          ],
           ),
           ),
            ),                      
                      ],
                    ),
                    color: Colors.white,
                  );
               },
               controller: _swiperController,
                      cardsCount: profiles.length,
                      onSwipe: (previousIndex, currentIndex, direction) {
                        
                        handleSwipe(previousIndex, direction, profiles,context);
                        return true; // Allow swipe
                      },),

Explanation:

• The CardSwiper widget is used to display a stack of swipeable cards.
• The cardBuilder function dynamically builds each profile card using profiles[index].
• Inside the card:
  •  A Container with a Column is used for layout.
  • The profile image is displayed using NetworkImage, with a fallback image in case the list is empty.
  • A Stack is used to overlay a gradient at the bottom for better text visibility.
  • The user’s name and age are displayed inside a semi-transparent container with a shadow effect.

• The onSwipe callback detects swipe actions, calling handleSwipe() to process the swipe logic.
• _swiperController is used to manage swipe interactions programmatically.

Conclusion

Integrating a Swiping Feature for Dating App using flutter_card_swiper provides developers with an easy yet powerful tool to implement Tinder-like swipe mechanics.
