Unhandled Exception: type 'Null' is not a subtype of type 'String' in type cast running from WINDOWS flutter

Steps to Reproduce Declare `@HiveType(typeId: 1) class Pings extends HiveObject { @HiveField(0) late String ip; @HiveField(1) late String mac; //mac @HiveField(2) late DateTime last_ping; @HiveField(3) bool connected=false; @HiveField(4) String user=" "; @HiveField(5) String pass=" "; @HiveField(6) String port=" ";

Pings({ required this.ip, required this.mac, //mac required this.last_ping, required this.connected, required this.user, required this.pass, required this.port });

@override String toString() { return 'Pings{ip: $ip, mac: $mac, name: $last_ping, connected:$connected, user: $user, pass:$pass, port:$port }'; } }`

Compile and works OK on flutter running on Android, but crash on start on flutter running on Windows with: "Unhandled Exception: type 'Null' is not a subtype of type 'String' in type cast running from WINDOWS flutter"

I think could be a database corrupted issue but can locate hive database path in Windows. Please provide path where hive stores databases in Windows?

Thanks and best regards

Code sample

Provide a few simple lines of code to show your problem.

Version

• Platform: iOS, Android, Mac, Windows, Linux, Web
• Flutter version: [e.g. 1.5.4]
• Hive version: [e.g. 0.5.0]

SOLVED: Like I though, was database corrupted problem. Solved deleting database by "hand" allocated in: "C:\Users\Admin\Documents" where "Admin" is your username. Delete files with ".hive" extension. Found path with the help of this code lines var appDir = await getApplicationDocumentsDirectory(); print(appDir.path);

I have also this bug with the 2.2.3 version. It's solved by deleting the boxes (.hive and .lock) as suggested by @casterock

[guvanch07]

are there any other ways to solve it?

Bump!

Currently having the same problem (for Android, not Windows), even though it works after deleting the boxes, as soon as I add any other data, I'll get the same error. Must say that the value pointed to be null, can not be, in any possible way, a null value. It'll always be a String.

Not an emulator problem, as it has been tested on 2 different emulators and on a physical device (S21 Ultra, if it is someone's interest).

Values are immutable and always defined at the class constructor as well.

if you are using an emulator/device

1. uninstall app from emulator or device
2. run flutter clean
3. run flutter pub get
4. flutter run

Found path with the help of this code lines var appDir = await getApplicationDocumentsDirectory(); print(appDir.path);

Any solution for web?!
