What do you think is the problem becuase we are developing an application that sets tasks and notifies the user of the specific task that he/she sets. When the user deletes a task and exits the application, when it is launched again, the deleted task comes back?
I really wish you can help our group. It is for our capstone project.
Because lists are not saved on phone, they are just temporary storage until app closes. You need to save your list to TinyDB (or another storage like Firebase) always when you change the list content. So you can access them when you open app.
