Tinder-Like Swipe Cards in Flutter

Article Summary

Anup Kumar Panwar built a dating app and hit a wall: existing Flutter swipe libraries were either slow or clunky. So he built his own and open-sourced it.

After testing multiple Flutter libraries for Kippy Dating App and finding none that delivered both performance and good UX, Panwar created swipe_cards—a lightweight module for Tinder-style card interactions. The package supports the three core gestures: left swipe (reject), right swipe (like), and up swipe (super like).

Problem

Anup Kumar Panwar looked at several Flutter libraries for Kippy Dating App, but none of them worked for what he needed. Some were slow, others gave users a poor experience.

Solution

Panwar dug through GitHub projects, StackOverflow threads, and Flutter docs to build swipe_cards, a custom Flutter module that handles left swipes, right swipes, and up swipes. It includes a MatchEngine controller so developers can trigger actions manually.

Impact

The swipe_cards package (version 0.0.4) is now open-sourced on pub.dev. Developers can use it to build Tinder-style card interactions without running into performance issues. Kippy Dating App uses it in production.
