Angular no longer exports RadioControlRegistry (ɵangular_packages_forms_forms_r)

[TrevorKarjanis]

🐛 Bug Report

The NimbleRadioControlValueAccessorDirective extends RadioControlValueAccessor which depends on RadioControlRegistry which is no longer exported from @angular/forms in Angular 13 and 14.

💻 Repro or Code Sample

Upgrade to Angular 13, and run npm run build.

🤔 Expected Behavior

As outlined in #732, public API should not be extended unless explicitly documented as supported. In addition, RadioControlRegistry is private.

😯 Current Behavior

✖ Compiling with Angular sources in Ivy partial compilation mode.

  Consider using the @Inject decorator to specify an injection token.

💁 Possible Solution

• Do the hackiest thing I've ever created in Angular.
• Jesse suggested submitting a feature request upstream.
• Reimplement the accessor.
• Start a nuclear winter; fork Angular.

🔦 Context

I am trying to upgrade Nimble to Angular 13 and 14.
