source property
Where stored documents are read from instead of DV.Database, or null.
A web app served by its own server (DVAuth.servedByOwnServer) reads
them from that server when nothing is set here: Studio publishes into
the server's database, and DV.Database in the browser is another one,
where nothing is ever published. Set for a test, or for an app whose
pages come from somewhere else.
Implementation
static Future<List<DVPageDocument>> Function()? source;
