Get ready to create a sleek and stylish credit card interface with just a few lines of code! With this package, you can easily customize the cardholder's name, card number, validity dates, and gradient colors to make it uniquely yours.
By default, the card will have a chic blue gradient and an NFC icon. But don't worry, if you don't want the NFC icon, simply pass doesSupportNfc: false.
Want to switch things up and place the NFC icon on the opposite side of the chip? No problem! Just enable it by passing placeNfcIconAtTheEnd: true, but remember to also pass doesSupportNfc: true.
Let's make your app look as sleek as that shiny new credit card!
CreditCardUi(
cardHolderFullName: 'John Doe',
cardNumber: '1234567812345678',
validFrom: '01/23',
validThru: '01/28',
topLeftColor: Colors.blue,
doesSupportNfc: true,
placeNfcIconAtTheEnd: true, // 👈 NFC icon will be at the end,
),
copied to clipboard

Custom Gradient
CreditCardUi(
cardHolderFullName: 'John Doe',
cardNumber: '1234567812345678',
validThru: '10/24',
topLeftColor: Colors.red,
bottomRightColor: Colors.purpleAccent,
),
copied to clipboard
This will create a credit card user interface with a red-to-purple gradient.

Setting the card width
If you want to set the width of the card, use width: property.
Better NOT wrap with SizedBox(width: ..., child: CreditCardUi(....)), instead use width: right from the CreditCardUi()
CreditCardUi(
width: 300, // 👈 this will set the width of the card
cardHolderFullName: 'John Doe',
cardNumber: '1234567812345678',
validThru: '10/24',
topLeftColor: Colors.red,
bottomRightColor: Colors.purpleAccent,
),
copied to clipboard
Note: Setting up any value more than 300 is not considered, maximum width can be 300 only.
Additional Customizations
To further customize the card, you can add a background image by using the backgroundDecorationImage property. Additionally, you can include a logo for the card provider using the cardProviderLogo property. This logo can be positioned on either the left or the right side of the card using the cardProviderLogoPosition property.
If you want to specify a particular card type to display, you can set it using the cardType property. If you prefer not to specify a card type, you can set cardType: CardType.other.
Here is an example of how to use these customization options:
Example:
CreditCardUi(
cardHolderFullName: 'John Doe',
cardNumber: '1234567812345678',
validFrom: '01/23',
validThru: '01/28',
topLeftColor: Colors.blue,
doesSupportNfc: true,
placeNfcIconAtTheEnd: true,
cardType: CardType.debit,
cardProviderLogo: FlutterLogo(), // 👈 Set your logo here, supports any widget
cardProviderLogoPosition: CardProviderLogoPosition.right,
backgroundDecorationImage: DecorationImage(
fit: BoxFit.cover,
image: NetworkImage( // 👈 `AssetImage` is also supported
'https://....',
),
),
),
copied to clipboard

To display the balance of your card, simply set showBalance: true and provide the balance amount using balance: 200.0 (any double value). Enabling autoHideBalance: true will generate a placeholder labeled "Tap to see balance". Users can then tap on this placeholder to reveal the balance.
CreditCardUi(
cardHolderFullName: 'John Doe',
cardNumber: '1234567812345678',
validFrom: '01/23',
validThru: '01/28',
topLeftColor: Colors.blue,
doesSupportNfc: true,
placeNfcIconAtTheEnd: true,
cardType: CardType.debit,
cardProviderLogo: FlutterLogo(),
cardProviderLogoPosition: CardProviderLogoPosition.right,
showBalance: true,
balance: 128.32434343,
autoHideBalance: true,
),
copied to clipboard
Card Flipping Animation
To enable the flipping animation by default, simply set the property enableFlipping: true. You can set CVV by cvvNumber: 000.
CreditCardUi(
cardHolderFullName: 'John Doe',
cardNumber: '1234567812345678',
validFrom: '01/23',
validThru: '01/28',
topLeftColor: Colors.blue,
doesSupportNfc: true,
placeNfcIconAtTheEnd: true,
cardType: CardType.debit,
cardProviderLogo: FlutterLogo(),
cardProviderLogoPosition: CardProviderLogoPosition.right,
showBalance: true,
balance: 128.32434343,
autoHideBalance: true,
enableFlipping: true, // 👈 Enables the flipping
cvvNumber: '123', // 👈 CVV number to be shown on the back of the card
),

Inspiration #
There are already many credit card packages out there, but none of them look realistic. So, I've decided to create something that will look the same as our cards in real life. Additionally, this project was inspired by a Native Android library.
