Features

• Product container accepts every widget.
• The cart and cart's badge can be invisible.
• The product animation is fully controlled(duration, curve)
• The first jump animation is fully controlled(active, duration, curve)

If you need it, you can add it to your project easily. It is easy to use

Add the dependency to your pubspec.yaml:

add_to_cart_animation: ^2.0.3

And check the example code to solve how it works.

import 'package:add_to_cart_animation/add_to_cart_animation.dart';
import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Add To Cart Animation Example',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Add To Cart Animation Example'),
      debugShowCheckedModeBanner: false,
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);
  final String title;

  @override
  MyHomePageState createState() => MyHomePageState();
}

class MyHomePageState extends State<MyHomePage> {
  // We can detect the location of the cart by this  GlobalKey<CartIconKey>
  GlobalKey<CartIconKey> cartKey = GlobalKey<CartIconKey>();
  late Function(GlobalKey) runAddToCartAnimation;
  var _cartQuantityItems = 0;

  @override
  Widget build(BuildContext context) {
    return AddToCartAnimation(
      // To send the library the location of the Cart icon
      cartKey: cartKey,
      height: 30,
      width: 30,
      opacity: 0.85,
      dragAnimation: const DragToCartAnimationOptions(
        rotation: true,
      ),
      jumpAnimation: const JumpAnimationOptions(),
      createAddToCartAnimation: (runAddToCartAnimation) {
        // You can run the animation by addToCartAnimationMethod, just pass trough the the global key of  the image as parameter
        this.runAddToCartAnimation = runAddToCartAnimation;
      },
      child: Scaffold(
        appBar: AppBar(
          title: Text(widget.title),
          centerTitle: false,
          actions: [
            //  Adding 'clear-cart-button'
            IconButton(
              icon: const Icon(Icons.cleaning_services),
              onPressed: () {
                _cartQuantityItems = 0;
                cartKey.currentState!.runClearCartAnimation();
              },
            ),
            const SizedBox(width: 16),
            AddToCartIcon(
              key: cartKey,
              icon: const Icon(Icons.shopping_cart),
              badgeOptions: const BadgeOptions(
                active: true,
                backgroundColor: Colors.red,
              ),
            ),
            const SizedBox(
              width: 16,
            )
          ],
        ),
        body: ListView(
          children: List.generate(
            15,
            (index) => AppListItem(
              onClick: listClick,
              index: index,
            ),
          ),
        ),
      ),
    );
  }

  void listClick(GlobalKey widgetKey) async {
    await runAddToCartAnimation(widgetKey);
    await cartKey.currentState!
        .runCartAnimation((++_cartQuantityItems).toString());
  }
}

class AppListItem extends StatelessWidget {
  final GlobalKey widgetKey = GlobalKey();
  final int index;
  final void Function(GlobalKey) onClick;

  AppListItem({super.key, required this.onClick, required this.index});
  @override
  Widget build(BuildContext context) {
    //  Container is mandatory. It can hold images or whatever you want
    Container mandatoryContainer = Container(
      key: widgetKey,
      width: 60,
      height: 60,
      color: Colors.transparent,
      child: Image.network(
        "https://cdn.jsdelivr.net/gh/omerbyrk/add_to_cart_animation/example/assets/apple.png",
        width: 60,
        height: 60,
      ),
    );

    return ListTile(
      onTap: () => onClick(widgetKey),
      leading: mandatoryContainer,
      title: Text(
        "Animated Apple Product Image $index",
      ),
    );
  }
}

By the way, you can run the example project in the plugin to check it deeply.

Have a good days.
