Breaking Changes

forms

• The shape of SignalFormsConfig.classes has changed

  Previously each function in the classes map took a FieldState. Now it takes a Field directive.

  For example if you previously had:

  provideSignalFormsConfig({
    classes: {
      'my-valid': (state) => state.valid()
    }
  })
  

  You would need to update to:

  provideSignalFormsConfig({
    classes: {
      'my-valid': ({state}) => state().valid()
    }
  })
  

  (cherry picked from commit 348f149e8b06d6885f54bac4cf03a9481a8b19b7)

• (cherry picked from commit ae0c59028a2f393ea5716bf222db2c38e7a3989f)
