I want to simply update table in database based on the checbox but its so difficult. Cant find a single answer. Very less material is available regarding flutter. I have a list of notes in listview which i get from note table in database. listview contains checkboxes. When I click on save button I want to update status columnn in note table for that particular note as "completed". Can anyone tell how do I do that. I have already posted the same question but I am not able to find my own question on stackoverflow.
