SpecCreationError class

A rejected node-creation attempt. Thrown by SpecNodeCreator.add and returned (rather than thrown) by checkAddNode.

Constructors

SpecCreationError({required String parentPath, required String childSegment, required SpecCreationCode code, required String message})

All four fields are required. code is what a caller branches on and message what it shows, while parentPath and childSegment say where: a rejection with no location cannot be surfaced against the tree the user is looking at. Note the pair names the attempted position, so joining them does not yield a path that exists — the whole point is that the add did not happen.
