 # Bayya
-
 An e-commerce flutter application.
-The application features:
+
+## Features
 * Shopping Cart & Watchlist tracking
 * User Login and registration support
+* Reviewing the products
+* Different views
+* Dynamic search mechanism
+
+## Challenges
+* Build list views on demand - less memory
+Using ```ListView.builder()``` instead of ```ListView()``` default constructor
+Example:
+More-memory consuming code
+
+```dart
+Widget _listOfProducts() {
+    return ListView(
+        padding: EdgeInsets.symmetric(vertical: 8.0),
+        children: //Check if the list is empty
+            Provider.of<ShoppingCart>(context).shoppingItemQuantites.isNotEmpty
+                ? Provider.of<ShoppingCart>(context)
+                    .shoppingItemQuantites
+                    .keys
+                    .map((e) {
+                    return ShoppingCartItem(productId: e);
+                  }).toList()
+                : []);
+}
+```
+
+Less-memory consuming code
+
+```dart
+Widget _listOfProducts() {
+    return ListView.builder(
+        padding: EdgeInsets.symmetric(vertical: 8.0),
+        // Get items count using Provider
+        itemCount: Provider.of<ShoppingCart>(context)
+            .shoppingItemQuantites
+            .keys
+            .length,
+        itemBuilder: (context, index) {
+          return ShoppingCartItem(
+              productId: Provider.of<ShoppingCart>(context)
+                  .shoppingItemQuantites
+                  .keys
+                  .elementAt(index));
+    });
+}
+```
+
+* Future code organization
+Using ```FutureBuilder``` instead of setting the state manually
+Example:
+Manual state management
+
+```dart
+String _vendor = 'Vendor not provided';
+
+Widget _vendorCard() {
+    _getVendorName();
+    return Container(
+      padding: const EdgeInsets.all(4),
+      margin: const EdgeInsets.only(bottom: 2),
+      color: Colors.white,
+      child: Column(
+        crossAxisAlignment: CrossAxisAlignment.start,
+        children: [
+          Row(
+            children: [Text('Vendor:')],
+          ),
+          Row(
+            children: [Text(_vendor)],
+          )
+        ],
+      ),
+    );
+}
+
+Future<void> _getVendorName() async {
+    var _result = await Provider.of<VendorsList>(context).getVendorNameByUid(
+        Provider.of<Catalog>(context).productsCatalog[widget.productId].vendor);
+    _vendor = _result;
+}
+```
+
+Future state managemet
+```dart
+Widget _vendorText() {
+    return FutureBuilder(
+        future: Provider.of<VendorsList>(context).getVendorNameByUid(
+            Provider.of<Catalog>(context)
+                .productsCatalog[widget.productId]
+                .vendor),
+        builder: (context, snapshot) {
+          if (snapshot.hasData) {
+            return Text(snapshot.data,
+                style: TextStyle(fontWeight: FontWeight.bold));
+          } else {
+            return Text("Vendor isn't provieded");
+          }
+        });
+}
+```
