I have this problem about updating my list of the in firebase. What I want to do is update 4 list of data. The touchHubLocatin, touchRemarks, touchDate and touchPersonName.
I use the Add to Set but it only add the item If it is not in the list. So is the I save the same person name it will not add to the list.
What my plan is I make a table to show the all the data Like this.
But I can't do that because I can't repeat the inbound or the same location because it say it wont add the same item in one list.
