title: What is the best practice to persist items inside a reorderablelist after change of order
body: <img src="https://i.stack.imgur.com/8dhZp.png" width="200" />
  <p>I have a reorderable list where i read the further information of each row on tap from a json file. Each row displays the corresponding json files name. I read these from a local folder in users device. The list shown here enables the user to reorder the items. The problem is I want to ensure persistent reodering by which I mean my app should remember the ordering user made next time the app is launched. I cannot think of anyway to go with this. Do I store a local json file keeping all the file names and the corresponding row index? What would be a best practice for this. This list is though to have row amount of 50 to 200 so I need a scalable solution.</p>
