🚀 Live demo · 📖 Docs

A dynamic widget system that renders e-commerce home/category screens from a backend-driven JSON payload. For the full widget catalog — one usage doc per widget type, with JSON schemas and examples — see doc/widgets/.

Installation

dependencies:
  serenay_ecommerce_widgets: ^1.1.5

Quick start

The package is backend-agnostic: navigation, data fetching, and auth/cart state are all injected from the host app through WidgetCallbacks.

final callbacks = WidgetCallbacks(
  onAction: (action) {
    // Navigate based on action.type (category, product, collection, ...).
  },
  fetchProducts: (query) => myApi.fetchProducts(query),
  fetchSlides: (id) => myApi.fetchSlides(id),
  isLoggedIn: () => myAuth.isLoggedIn,
  onToggleFavorite: (product) => myApi.toggleFavorite(product.id),
  onAddToCart: (product, variant, qty) => myCart.add(product, variant, qty),
);

final screenJson = await myApi.fetchScreen(); // { "data": [ ... ] }
final data = WidgetCatalog.fromJson(screenJson);

ListView(children: WidgetCatalog.getScreen(data: data, callbacks: callbacks));

Only onAction and fetchProducts are required on WidgetCallbacks; callbacks for widget types you don't use (fetchVideos, fetchModal, visitedProducts, ...) can be left unset — the corresponding widget just hides itself when no data comes back, it never crashes.

See example/lib/main.dart for a complete working example: a mock JSON payload and mock callbacks driving a demo screen with every catalog widget.

Theming

By default every widget uses the package's built-in colors and text styles. To re-brand the catalog for your app, pass an EcommerceWidgetTheme to getScreen:

final theme = EcommerceWidgetTheme(
  primaryColor: const Color(0xFF7B2CBF),
  secondaryColor: const Color(0xFFFF9F1C),
  discountColor: const Color(0xFFE63946),
  productTitleStyle: const TextStyle(fontWeight: FontWeight.w700),
);

WidgetCatalog.getScreen(data: data, callbacks: callbacks, theme: theme);

Any field you don't set falls back to the package default — see EcommerceWidgetTheme for the full list of overridable colors, text styles and sizes.

The standalone building blocks the catalog composes internally — AddToCartButton, FavoriteButton, DiscountBadge, QuantityPicker, RichProductCard — are also exported, so you can use them directly outside WidgetCatalog (e.g. in a custom product detail screen) with their own constructor overrides.

Supported widgets

TEXT, IMAGE, SLIDER, DIVIDER, CAROUSEL, GRID, IMAGECAROUSEL, IMAGELIST, VIDEOLIST, FASTREGISTER, STORY, VISITEDPRODUCTS, TIMEIMAGE, YOUTUBE, SEARCH, PRODUCTCARD, FLASHSALE, MODAL, MIXEDCAROUSEL. An unrecognized type renders as an empty 1px box (forward compatibility).

GRID has its own card design (taller image, inline video, a pre-order banner, a size/package picker); CAROUSEL, PRODUCTCARD and FLASHSALE share the same card.

For the params schema each widget expects, see doc/widgets/ — one page per widget type.
