type MaybeSchemaPathTree<TModel, TPathKind extends PathKind = PathKind.Root> = | (TModel & undefined) | SchemaPathTree<Exclude<TModel, undefined>, TPathKind>
Description
Helper type for defining FieldPath. Given a type TValue that may include undefined, it extracts the undefined outside the FieldPath type.
For example MaybeFieldPath<{a: number} | undefined, PathKind.Child> would be equivalent to undefined | FieldTree<{a: number}, PathKind.child>.
