Hive: Error: You have to provide a non-null typeId

[sgehrman]

[SEVERE] hive_generator:hive_generator on lib/hive_db/scan_data.dart:
Error running TypeAdapterGenerator
You have to provide a non-null typeId.

I'm trying to follow the reso coder video. He had the same issue, but didn't explain the work around.

[sgehrman]

Figured it out:

@HiveType(typeId: 0)

@sgehrman Yes, and you need to manually assign different type id's (integers) to your each one of your models

Please close this issue if it works now :+1:

Update the documentation and be friendly to novices.

An exception should probably be thrown to the IDE, or intellisense should catch if an ID is not provided to the HiveType without having to go through a build attempt to catch this.

Figured it out:

@HiveType(typeId: 0)

Can be added to the docs?
