Why Use a Credit Card View in Flutter?

A well-designed credit card UI improves user trust and reduces form errors.

With Flutter, you can:

• Show a real-time card preview
• Detect card type automatically
• Animate card flipping for CVV input
• Validate card details instantly

The flutter_credit_card package handles all of this efficiently.

What Is flutter_credit_card?

flutter_credit_card is a popular Flutter package that:

• Provides a ready-made credit card UI
• Supports card number masking
• Includes flip animation for CVV
• Automatically detects card brands (Visa, MasterCard, etc.)

It is actively maintained and compatible with the latest Flutter stable versions.

How to implement credit card UI in Flutter:-

Step 1: Add Dependency

First, we need to create a new Flutter project and add the following dependencies to the pubspec.yaml file.

dependencies:
  flutter
    sdk: flutter
  flutter_credit_card: ^4.1.0

Now, run the command “flutter pub get” to add the dependencies.

To include the required package, please add it to your class.

import 'package:flutter_credit_card/flutter_credit_card.dart';

Step 2: Create Stateful Widget

We use a StatefulWidget because the card details change when the user types.

class CreditCard extends StatefulWidget {
  const CreditCard({super.key});

  @override
  State<CreditCard> createState() => CreditCardView();
}

Step 3: How to display credit card preview?

Some essential fields in CreditCardWidget(), such as creating a card number, which enables the user to enter their card number for card identification, must be null.

CreditCardWidget(
  cardNumber: cardNumber,
  expiryDate: expiryDate,
  cardHolderName: cardHolderName,
  cvvCode: cvvCode,
  bankName: 'Axis Bank',
  showBackView: isCvvFocused,
  obscureCardNumber: true,
  obscureCardCvv: true,
  isHolderNameVisible: true,
  cardBgColor: Colors.blueGrey.shade700,
  onCreditCardWidgetChange: (_) {},
)

Step 5: How to build credit card input form?

This form allows users to enter card details.

CreditCardForm(
  formKey: formKey,
  cardNumber: cardNumber,
  expiryDate: expiryDate,
  cvvCode: cvvCode,
  cardHolderName: cardHolderName,
  obscureCvv: true,
  obscureNumber: true,
  onCreditCardModelChange: onCreditCardModel,
)

Step 6: Listen to Card Input Changes

This method updates the card preview in real time.

void onCreditCardModel(CreditCardModel model) {
  setState(() {
    cardNumber = model.cardNumber;
    expiryDate = model.expiryDate;
    cardHolderName = model.cardHolderName;
    cvvCode = model.cvvCode;
    isCvvFocused = model.isCvvFocused;
  });
}

How Do You Handle Form Validation:

We use a GlobalKey<FormState> method to validate user input.

final GlobalKey<FormState> formKey = GlobalKey<FormState>();

This allows us to check whether all card details are valid before proceeding.

The formkey will be added to this CreditCardForm(). The ultimate globalkey is user-created.

How Do You Customize Input Fields?

Flutter allows full control over input decorations.

You can customize:

• Card number field
• Expiry date field
• CVV field
• Card holder name field

Each field supports custom borders, labels, and error styles.
