How to Make a ERP App with Flutter

Inventory Management

class InventoryItem {
  final String sku, name;
  int quantity;
  final int minThreshold;
  final String warehouse;

  InventoryItem({required this.sku, required this.name, this.quantity = 0,
    this.minThreshold = 10, required this.warehouse});

  bool get lowStock => quantity <= minThreshold;
}

class InventoryTable extends StatelessWidget {
  final List items;

  const InventoryTable({super.key, required this.items});

  @override
  Widget build(BuildContext context) {
    return DataTable(
      columns: const [
        DataColumn(label: Text('SKU')),
        DataColumn(label: Text('Name')),
        DataColumn(label: Text('Qty'), numeric: true),
        DataColumn(label: Text('Status')),
      ],
      rows: items.map((item) => DataRow(
        color: item.lowStock ? MaterialStateProperty.all(Colors.red.shade50) : null,
        cells: [
          DataCell(Text(item.sku)),
          DataCell(Text(item.name)),
          DataCell(Text(item.quantity.toString())),
          DataCell(Icon(
            item.lowStock ? Icons.warning : Icons.check_circle,
            color: item.lowStock ? Colors.red : Colors.green,
          )),
        ],
      )).toList(),
    );
  }
}

UI & UX Suggestions

Use a clean white theme, red alerts for low stock, green for positive colour palette to match the app's purpose. Keep the navigation simple — a bottom nav bar or a single-scroll layout works best for this type of app. Make sure every interaction provides haptic or visual feedback so the app feels responsive and polished.
