[QGIS-Developer] Project definition specifics

[andrea antonello]

Dear Nyall,
thanks a ton for your reply.

Short answer is: formal schema specs don't exist.

That did indeed help a lot, even if not in the direction I hoped for.
I don't have the luxury to access the QGIS API. The mobile app is written
in flutter and that is the language I will have to use, so reading xml
would be a must.
That said, I assume I have 2 possibilities:
1. forget about it
2. start supporting bits and pieces of the project file and try to maintain
it for specific versions, but that sounds like a little nightmare.

Thanks again,
Andrea
