Building a Tinder-like Dating App with Flutter
Are you interested in creating a dating app similar to Tinder? In this article, we’ll explore how to develop a dating app using Flutter. We’ll cover the key classes and widgets needed to build a basic card stack, create profile cards, make them draggable, and add like and dislike action buttons.
Our Flutter Dating App
The app is simple: users swipe right to like and left to dislike. The app features a red arc background with a title and a stack of cards for different profiles above it. Under the cards are like and dislike buttons that users can use instead of swiping.
Starting with a Basic Card Stack
To create the UI, we’ll split it into two widgets:
- BackgroundCurveWidget: This widget will contain the red arc gradient background.
- CardsStackWidget: This widget will contain the stack of cards along with like and dislike buttons.
Creating Profile Cards
We’ll create a model class to hold the information required by the profile card. The profile card will include a vertical image, person’s name, and distance.
Making ProfileCard Draggable
We’ll use the Draggable widget to make the profile card draggable. We’ll also use ValueNotifier and ValueListenableBuilder to rebuild the widget when the user drags the card.
Building a Stack of Draggable Cards with DragTarget
We’ll create a stack of draggable cards with a DragTarget widget. The DragTarget widget will accept a draggable card when it’s dropped inside it.
Making Like and Dislike Action Buttons
We’ll create two action buttons at the bottom of the screen. These buttons will allow users to like or dislike a profile without swiping the card.
Putting it all Together
After making all the necessary changes, our CardsStackWidget code will look like this:
“`dart
class CardsStackWidget extends StatefulWidget {
@override
_CardsStackWidgetState createState() => _CardsStackWidgetState();
}
class _CardsStackWidgetState extends State
// …
}
“`
And that’s it! Our dating app is complete. Run the application and enjoy!
