Flutter Unhandled Exception: LateInitializationError: Local 'name' has not been initialized - firebase

Question

I have a flutter app which tries to compare two sets of app version numbers, the first version number is stored locally using hive and the second version number is from firestore. I can fetch the data from firestore but I cannot get to compare both since it takes a while to fetch data from firestore.
This is the code to fetch data from firestore
late final Box detailsBox;
#override
void initState() {
super.initState();
detailsBox = Hive.box('appDetails');
updateApplication();
}
CollectionReference groceries =
FirebaseFirestore.instance.collection('updates');
late String? name;
late String? version;
late String? downloadUrl;
getData() {
groceries.orderBy('name').snapshots().listen((gets) {
try {
for (var gettt in gets.docs) {
name = gettt['name'] ?? 'null';
version = gettt['version'] ?? 'null';
downloadUrl = gettt['download url'] ?? 'null';
debugPrint('name: $name');
debugPrint('version: $version');
debugPrint('downloadUrl: $downloadUrl');
_addInfo(name!, version!, downloadUrl!); }
} catch (e) {
print(e);
}
});
}
This is the code to compare the version numbers
int getExtendedVersionNumber(String version) {
List versionCells = version.split('.');
if (kDebugMode) {
print(versionCells);
}
versionCells = versionCells.map((i) => int.parse(i)).toList();
return versionCells[0] * 10000 + versionCells[1] * 100 + versionCells[2];
}
Future compareData() async {
await getData();
String localName = detailsBox.get('name');
String localVersion = detailsBox.get('version');
String downloadLink = detailsBox.get('downloadLink');
debugPrint(
'Info retrieved from detailsBox below:\n $localName\n ($localVersion) \n $downloadLink');
debugPrint(
'Info retrieved from firebase below:\n $name\n ($version) \n $downloadUrl');
int version1Number = getExtendedVersionNumber(localVersion); // return 102003
int version2Number = getExtendedVersionNumber(version!); // return 102003
if (kDebugMode) {
print(version1Number == version2Number);
print(version1Number > version2Number);
print(version1Number < version2Number);
}
if (version2Number > version1Number) {
debugPrint('true');
debugPrint(downloadUrl);
}
}
When it gets to this point debugPrint( 'Info retrieved from firebase below:\n $name\n ($version) \n $downloadUrl'); I get the late initialization error [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: LateInitializationError: Field 'name' has not been initialized.
How can I modify the code such that when it runs I can account for the time it takes to get data then finally compare the versions

Answer 1

Just change
late String? name;
to
String? name;
