(Puts on her teacher hat:) What guide on the internet? What specifically are you confused about? We’d like to help you, but need more details. 
What i trying to do is actually when i click the food item, it will automatically assign to cart, and the quantity increasing each click. Please guide me how to do so…
You can first create a Local DB called ‘cart items’. Add a column called ‘item rowID’. This will hold the rowID of the clicked item to add to the cart, so it can be referenced later. Then, add a
when data_viewer_list1 click
block.
Inside that, put,
DataViewerList cart items create row
RowID value = rowid( the green block that comes with when dataviewerlist click).
