Question

these rules show me error Error saving rules - Line 5: Expected '{'. Please help

Answer 1

Firebase Realtime Database rules don't support a ".delete" clause, and that's the reason you get this error message. Correct rules are:

{ 
  "rules": { 
    ".read": true, 
    ".write": true 
  } 
}

These rules will also allow deleting of the data, as part of the .write rule.

If you want to later disallow deletes or other types of updates, have a look at the documentation on new data vs existing data.
