Hive asks unknown typeId to be registered

[ampersanda]

Steps to Reproduce

A newly fresh project and setup for Hive and I don't have an Adapter which has 33 typeId . This happens when I hot restart the current project and the way to fix this is by deleting the application. Here's short [Youtube Video] for (https://www.youtube.com/watch?v=l59ysgMz1uk&feature=youtu.be)

Here's the error

You need to swap these two lines:

await Future.wait([Hive.openBox<Note>('notes')]);
Hive.registerAdapter<Note>(NoteAdapter());

The adapter needs to be registered before you open a box.

Thank you, it's fix this issue 🙃
