Check if ListView is empty in flutter

Question

Is there a way to check if ListView is empty.

ListView.builder(
  itemCount: _items.length,
  itemBuilder: (context, index) {
    return _buildFilteredItem(context, index);
  },
)

I want to search through my items and if its empty show a Text widget saying no items found. _buildFilteredItem returns null if the item could not be found.

Answer 1

Check _items before creating ListView

return _items.isEmpty ? Center(child: Text('Empty')) : ListView.builder(
  itemCount: _items.length,
  itemBuilder: (context, index) {
    return _buildFilteredItem(context, index);
  },
)
