Animation Flip card in flutter

Getting Started

Introduction:

Flutter, Google’s open-source UI framework, has gained immense popularity for building beautiful and highly customizable user interfaces across various platforms. Among its many features, Flutter provides the flexibility to create interactive and visually appealing widgets, such as flip cards. Flip cards are a great way to display information on one side and reveal additional details on the other with a smooth animation. In this article, we will explore how to create flip cards in Flutter.

Adding Dependencies

To create flip cards, we’ll need to add a package that provides this functionality. A popular choice is the `flip_card` package. To add it to your project, open your `pubspec.yaml` file and add the following dependency:

flip_card: ^0.6.0

Save the file, and then run `flutter pub get` to fetch the package.

Creating a Basic Flip Card

FlipCard(
      direction: FlipDirection.HORIZONTAL,
      onFlip: _flipCard,
      front: Card(
        elevation: 4.0,
        child: Container(
          height: 200.0,
          alignment: Alignment.center,
          child: Image.asset('assets/icons8-flutter-480.png'),
        ),
      ),
      back: Card(
        elevation: 4.0,
        color: Colors.blue,
        child: Container(
          height: 200.0,
          alignment: Alignment.center,
          child: Image.asset(widget.backText),
        ),
      ),
    );

Adding Animation

To make the flip animation smoother, you can set the `flipOnTouch` property to `true`. This will make the card flip when you tap it.

FlipCard(
  flipOnTouch: true,
  // ...
)

Adding a Custom Flip Animation

You can also create custom flip animations by using the `flipBuilder` property. This allows you to define your animation behavior.

FlipCard(
  flipBuilder: (BuildContext context, bool isFront) {
    return AnimatedBuilder(
      animation: controller,
      builder: (BuildContext context, Widget child) {
        // Implement your custom animation here
      },
    );
  },
  // ...
)

Adding Callbacks

FlipCard(
  onFlip: () {
    // Perform actions when the card is flipped
  },
  // ...
)

Conclusion

Creating flip cards in Flutter is a great way to add interactive elements to your apps. The `flip_card` package provides an easy-to-use solution for creating flip cards with various customization options. By following the steps and customizations outlined in this article, you can create engaging and dynamic user interfaces in your Flutter applications.
