# Shopping configurations (Flutter)

### Customize product info view

You could utilize `FireworkSDK.getInstance().shopping.productInfoViewConfiguration` to customize the shopping CTA button, the Firework PDP link button, and the video product card.

#### Create a configuration for shopping CTA button

```dart
final shoppingCTAConfiguration = ShoppingCTAButtonConfiguration(
  // The text of shopping CTA button: "Shop now" or "Add to card"
  text: ShoppingCTAButtonText.shopNow,
  // The text color of CTA button
  // Only supported on iOS
  textColor: "#000000",
  // The background color of CTA button
  // Only supported on iOS
  backgroundColor: "#c0c0c0",
  // The text color of CTA button
  // Only supported on iOS
  fontSize: 16,
  // iOS font info
  iOSFontInfo: IOSFontInfo(
    fontName: "Helvetica",
    systemFontStyle: IOSSystemFontStyle.italic,
    systemFontWeight: IOSSystemFontWeight.heavy,
  ),
);
```

#### Create a configuration for Firework PDP link button

```dart
final linkButtonConfiguration = LinkButtonConfiguration(
  // Specifies if the link button should be hidden
  isHidden: true,
);
```

#### Create a configuration for video product card

```dart
final productCardConfiguration = ProductCardConfiguration(
  // The theme of video product card
  theme: ProductCardTheme.light,
  // The corner radius of video product card
  cornerRadius: 10,
  // Specifies if the CTA button should be hidden
  isCtaButtonHidden: true,
  // The text of shopping CTA button: "Buy now" or "Shop now"
  ctaButtonText: ProductCardCTAButtonText.buyNow,
  // The cta button style of video product card
  // Only supported on iOS
  ctaButtonStyle: ProductCardCTAButtonStyle(
    textColor: "#000000",
    fontSize: 16,
    iOSFontInfo: IOSFontInfo(
      fontName: "Helvetica",
      systemFontStyle: IOSSystemFontStyle.italic,
      systemFontWeight: IOSSystemFontWeight.heavy,
    ),
  ),
  // The price configuration of video product card
  priceConfiguration: ProductCardPriceConfiguration(
    // The axis of price label: horizontal or vertical
    // Only supported on iOS
    axis: ProductCardPriceLabelAxis.horizontal,
    // The label configuration of price
    // Only supported on iOS
    priceLabel: ProductCardLabelConfiguration(
      textColor: "#000000",
      fontSize: 16,
      numberOfLines: 2,
      iOSFontInfo: IOSFontInfo(
        fontName: "Helvetica",
        systemFontStyle: IOSSystemFontStyle.italic,
        systemFontWeight: IOSSystemFontWeight.heavy,
      ),
    ),
    // The label configuration of original price
    // Only supported on iOS
    originalPriceLabel: ProductCardLabelConfiguration(
      textColor: "#000000",
      fontSize: 16,
      numberOfLines: 2,
      iOSFontInfo: IOSFontInfo(
        fontName: "Helvetica",
        systemFontStyle: IOSSystemFontStyle.italic,
        systemFontWeight: IOSSystemFontWeight.heavy,
      ),
    ),
    // The default display order is [priceLabel, originalPriceLabel]
    // When the value is `true`, the order is reversed
    // Only supported on iOS
    isPriceFirst: true,
  ),
  // The width of video product card
  // Only supported on iOS
  width: 240,
  // The height of video product card
  // Only supported on iOS
  height: 150,
  // The background color of video product card
  // Only supported on iOS
  backgroundColor: '#c0c0c0',
  // The label configuration of video product name
  // Only supported on iOS
  nameLabel: ProductCardLabelConfiguration(
    textColor: "#000000",
    fontSize: 16,
    numberOfLines: 2,
    iOSFontInfo: IOSFontInfo(
      fontName: "Helvetica",
      systemFontStyle: IOSSystemFontStyle.italic,
      systemFontWeight: IOSSystemFontWeight.heavy,
    ),
  ),
  // The icon configuration of product icon
  // Only supported on iOS
  iconConfiguration: ProductCardIconConfiguration(cornerRadius: 10),
);
```

#### Apply configurations

You could utilize `FireworkSDK.getInstance().shopping.productInfoViewConfiguration` to apply these configurations.

```dart
FireworkSDK.getInstance().shopping.productInfoViewConfiguration =
    ProductInfoViewConfiguration(
  ctaButton: shoppingCTAConfiguration,
  linkButton: linkButtonConfiguration,
  productCard: productCardConfiguration,
);
```

{% hint style="info" %}
If you wish to customize the video product card with a custom view, please refer to [Customize product card on videos using the custom view (Flutter)](/firework-for-developers/flutter-sdk/integration-guide-v2/customization/shopping-configurations-flutter/customize-product-card-on-videos-using-the-custom-view-flutter.md).
{% endhint %}

### Show cart icon

The cart icon is hidden by default. You could show the cart icon with the following codes:

```dart
FireworkSDK.getInstance().shopping.cartIconVisible = true;
```

### Show the red indicator on the cart icon

The host app could use FireworkSDK.getInstance().shopping.setCartItemCount to sync the cart item count to Firework SDK. The count should be greater than or equal to 0. We just use count to show or hide the red indicator on the cart icon. If count > 0, we will show the red indicator on the cart icon. Otherwise, we will hide the red indicator on the cart icon.

```dart
FireworkSDK.getInstance().shopping.setCartItemCount(cartItemCount);
```
