RecreatorClassConfig class

Configuration for a single-type-parameter widget that must be re-created (rather than relaxer-wrapped) with a script-supplied type argument.

Some immutable Flutter widgets — DropdownMenuItem<T>, DropdownMenuEntry<T>, ButtonSegment<T> — cannot be wrapped by a $Relaxed subclass (they are immutable and drive complex rendering). Instead the generator emits a D4.registerGenericTypeWrapper re-creator that reconstructs the widget with the correct <T> by reading the constructor parameters back from the same-named instance getters.

Each entry lists the className and the concrete innerTypes for which a switch arm is emitted (in addition to the always-present dynamic/Object arm). Used by the relaxer generator's re-creator emitter (recreatorClasses).

Example in buildkit.yaml:

d4rtgen:
  recreatorClasses:
    - DropdownMenuItem
    - className: ButtonSegment
      innerTypes: [String, int]

Constructors

RecreatorClassConfig({required String className, List<String> innerTypes = defaultInnerTypes})

const

RecreatorClassConfig.fromJson(Map<String, dynamic> json)

factory

RecreatorClassConfig.fromYaml(Object value)

Parse from a simple string (just the class name) or a map.
