You could use this functions to persist and load data from shared preferences.

Get SharedPreferences from here.

To persist data to SharedPreferences, called after adding or deleting a new element to the list.

_persistData() async {
    SharedPreferences preferences = await SharedPreferences.getInstance();
    await preferences.setStringList("persons", _people);
  }

To load data from SharedPreferences, usually called in initState.

_loadData() async {
    SharedPreferences preferences = await SharedPreferences.getInstance();
    setState(() {
      _people = preferences.getStringList("persons");
    });
  }
