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.

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