If you’re working on a Flutter application that requires a credit card input, you’ve come to the right place! The credit_card_input_form package provides a visually appealing way to gather credit card information with smooth animations. In this guide, we’ll show you how to set it up and troubleshoot any potential issues.

Installing the Package

• Add Dependency: Open your pubspec.yaml file and include the following dependency:

dependencies:
  credit_card_input_form: ^2.3.0

• Import the Package: In your Dart file, import the package:

import 'package:credit_card_input_form/credit_card_input_form.dart';

Using the Credit Card Input Form

To implement the CreditCardInputForm, you can customize various aspects of it. Below is an example snippet:

CreditCardInputForm(
  cardHeight: 170,
  showResetButton: true,
  onStateChange: (currentState, cardInfo) {
    print(currentState);
    print(cardInfo);
  },
  customCaptions: ...,
  frontCardDecoration: cardDecoration,
  backCardDecoration: cardDecoration,
  prevButtonDecoration: buttonStyle,
  nextButtonDecoration: buttonStyle,
  resetButtonDecoration: buttonStyle,
  prevButtonTextStyle: buttonTextStyle,
  nextButtonTextStyle: buttonTextStyle,
  resetButtonTextStyle: buttonTextStyle,
  initialAutoFocus: true,
);

Understanding the Code with an Analogy

Think of the CreditCardInputForm as a beautiful restaurant menu. Just like how each dish has its own presentation and description, each parameter in the code customizes the form’s appearance and functionality.

• cardHeight: This is like the height of the menu – it dictates how prominent your offerings are.
• showResetButton: This is akin to a “clear all orders” option. It allows users to start fresh.
• onStateChange: Imagine this as your waiter who notes the customer’s reactions as they enjoy their meal, providing feedback.
• customCaptions: These are the special notes beside each dish, enhancing the customer’s understanding.
• frontCardDecoration: and backCardDecoration: are like the design of the menu – whether it looks classy or casual.

New Features

Version 1.3.0 introduced a custom button style feature, allowing you to change the aesthetics of action buttons with customizable decorations. Below is an example:

final buttonDecoration = BoxDecoration(
  borderRadius: BorderRadius.circular(30.0),
  gradient: LinearGradient(
    colors: [
      const Color(0xfffcdf8a),
      const Color(0xfff38381),
    ],
    begin: const FractionalOffset(0.0, 0.0),
    end: const FractionalOffset(1.0, 0.0),
    stops: [0.0, 1.0],
    tileMode: TileMode.clamp),
);

Using this, you can give a unique look to your buttons that aligns with your application’s theme.
