Hive: Moving boxes to another device

[ScitoolsKen]

Question
We have the same app running on multiple devices entering data into forms.
We would like to synchronize changes in forms on the remote devices to a master tablet.
My team has been doing a conversion to Box -> SON, transport JSON, JSON->BOX, merge.

I wonder why can't we just move the boxes, open them up on the receiving end, merge differences.

We are basically writing stuff to boxes and writing equivalent code to write / read into JSON, and I wonder why not just do it once?

Version
Android/ioS
Latest version of flutter and hive.

Thanks,

Ken Nelson

You can also transfer box file, read & parse on other end then copy data to the box on endpoint.

@TheMisir I'm currently trying to move the full boxes to a backup location and restore/overwrite the full boxes on request.
Converting box.values or box.toMap() to JSON currently seems a lot of unnecessary work (since I'm storing custom data models), if there would be any way to just get a hold of the full box-files or box-file-contents as a single string (being on iOS/Android). Do you have any hints for me?

[TheMisir]

You can copy database file itself. The .hive files is stored in getApplicationDocumentsDirectory() directory.

Just in case anyone looking for way to do it in a "string"-way when copying isn't the best option:
