Error: "type 'UnspecifiedInvalidResult' is not a subtype of type 'LibraryElementResult' in type cast" in Flutter Hive
Solution 1
I was finally able to fix this by deleting my pubspec.lock file and running flutter pub get again.
Solution 2
I was facing the same problem right now. Finally figured out what I was doing wrong.
The solution is the name of the dart file should be used in part"file_name.g.dart";
and there should be no gaps in the file name. For example, my dart file name was Data Entry.dart
and I was using part"entries.g.dart";
. That's why it was showing this error. Then I changed the code to part"Data Entry.g.dart";
. It was still showing the error.
Then finally I changed the file name to entries.dart
and used part"entries.g.dart";
and it worked fine.
Solution 3
I was able to fix this by deleting my pubspec.lock file, run flutter clean
and running flutter pub get
again.

I run
flutter packages pug run build_runner build
, the normal command with which you would create a TypeAdapter in Flutter, I get the following error:type 'UnspecifiedInvalidResult' is not a subtype of type 'LibraryElementResult' in type cast
It says that It founds the error In the following file:
import 'dart:core'; import 'package:hive/hive.dart'; part 'storedItem.g.dart'; @HiveType(typeId: 1) class Person extends HiveObject { @HiveField(0) String name; @HiveField(1) int age; Person({required this.name, required this.age}); }
I mean that's the Code of the documentation! What did I wrong?
