DiagramPropertyEditor class final

Renders the custom properties whose value type is T in an inspector.

A DiagramProperty.custom declares its value type; the editor for that type builds its control. The field carries the value (or the mixed state of a multi-selection), whether it is enabled or read-only, and writes through the controller: DiagramPropertyField.set for one undoable change and DiagramPropertyField.begin for a preview-then-commit edit such as a drag. After asynchronous work, such as a dialog, pass expectedRevision: field.revision so a stale choice becomes a conflict.

DiagramPropertyEditor.of<Owner>(
  (context, field) => OwnerPicker(
    owner: field.value,
    onChanged: field.set,
  ),
)
