How can create a backup system . Can anyone help me
Be more specific
Make an Application specific directory
Then create a Folder named “Backup” in the directory
Then Lets suppose its a Chat application
When you get all data from firebase, make it a dictionary for easier storing and convert all your messages into a json and store it in the txt file.
And then save the file in the Backup folder.
There u go.
Now using a date or timer save it every once a while or as u wish.
