I want to know the point behind calling setState
without setting a new value to the variables.
readLocal() async {
prefs = await SharedPreferences.getInstance();
id = prefs.getString('id') ?? '';
if (id.hashCode <= peerId.hashCode) {
groupChatId = '$id-$peerId';
} else {
groupChatId = '$peerId-$id';
}
setState(() {});
}
