Creating Dynamic Card Carousels with Polaroid Carousel in Flutter

Introduction:

Flutter, the open-source UI software development toolkit by Google, empowers developers to build beautiful and interactive user interfaces. If you’re looking to add a unique touch to your app, consider using the “polaroid_carousel” package, which enables you to create dynamic rotating card carousels effortlessly.

Getting Started:

To begin, add the “polaroid_carousel” package to your Flutter project by including it in your pubspec.yaml file. Installation is straightforward and can be done with a single command.

#Installation

#To use this package, follow these steps:

#1. Add the latest version of the package to your `pubspec.yaml` file and run `dart pub get`:

   dependencies:
     polaroid_carousel: ^1.0.0

#2. Import the package in your Dart code and use it in your Flutter app:

   import 'package:polaroid_carousel/polaroid_carousel.dart';

Usage:

Polaroid Carousel allows you to craft captivating carousels with ease. Define your list of widget items and set the translation factor. For items with rotation, wrap each child with a Transform widget and specify the rotateZ angle to your liking.

Customization:

You have full control over the carousel’s animation order(frontToBack or backToFront), translation(left or right or top or bottom), and rotation(x,y,z). Tailor it to your app’s unique requirements, whether you want a front-to-back or back-to-front animation order.

Example:

import 'package:flutter/material.dart';
import 'dart:math' show pi;
import 'package:polaroid_carousel/polaroid_carousel.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: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const Example(),
    );
  }
}

class Example extends StatelessWidget {
  const Example({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    List<Widget> list = [
      Container(
        transformAlignment: Alignment.center,
        transform: Matrix4.identity()..rotateZ(pi / 8),
        height: 200,
        width: 300,
        color: Colors.black,
      ),
      Container(
        transformAlignment: Alignment.center,
        transform: Matrix4.identity()..rotateZ(pi / 40),
        height: 200,
        width: 300,
        color: Colors.blue,
      ),
      Container(
        transformAlignment: Alignment.center,
        transform: Matrix4.identity()..rotateZ(pi / 15),
        height: 200,
        width: 300,
        color: Colors.brown,
      ),
      Container(
        transformAlignment: Alignment.center,
        transform: Matrix4.identity()..rotateZ(-pi / 15),
        height: 200,
        width: 300,
        color: Colors.red,
      ),
      Container(
        transformAlignment: Alignment.center,
        transform: Matrix4.identity()..rotateZ(-pi / 8),
        height: 200,
        width: 300,
        color: Colors.grey,
      ),
      Container(
        transformAlignment: Alignment.center,
        transform: Matrix4.identity()..rotateZ(-pi / 40),
        height: 200,
        width: 300,
        color: Colors.yellow,
      ),
    ];

    return Scaffold(
      body: Center(
          child: PolaroidCarousel(
        //these to property are necessary

        // value to which list item translate
        // advice : if the children are rotated like the example and you are not able to specify the translateFactor
        // then the max translateFactor should be √((childHeight^2, childWidth^2)) of child with maximum size
        //but try to adjust translateFactor according to your need
        translateFactor: 360,

        children: list,

        // these properties are optional

        // duration: const Duration(seconds: 1),
        // rotate: const Rotate(x: 0.001,y: 0.02,z: 0.001),
        // curve: Curves.easeInOut,
        // order: Order.frontToBack,
        // translate: Translate.top,
      )),
    );
  }
