FieldCodec class

Defines read and literal commit behavior for one registered canvas field.

Field-specific normalization and invariants belong here. Persistent changes produced by a codec should be routed through EditorController.applyEdit.

Constructors

FieldCodec({required Object fallback, ReadNodeFn? readNode, ReadSceneFn? readScene, required CommitFn commit, bool isSceneOnly = false})
