Add onIsDirtyChange prop

Add onIsDirtyChange prop to FormsProvider props to make it easier to react to dirty state changes.

Add missing `children` prop to `FormsProviderProps` for React v18.

v3.1.0

chore(release): 3.1.0

Add `isInitError`

Add isInitError which will maintain initHasError during the constructor.

Otherwise if you set initHasError based on a server condition that isn't checked inside isValid, the error state will immediately be lost.

This could be considered a breaking change since initHasError will behave different, but it's also a bug fix.

Fix bug with iterating over `FormData` keys

v2.1.6

FormData Support

Add initializeFromFormData function to set the initValue of FormFieldConfigs using the FormData specified.
