/**
 * Base custom create request class for registering a credential.
 *
 * An application can construct a subtype custom request and call
 * [CredentialManager.createCredential] to launch framework UI flows to collect consent and
 * any other metadata needed from the user to register a new user credential.
 *
 * If you get a [CreateCustomCredentialRequest] instead of a type-safe request class such as
 * [CreatePasswordRequest], [CreatePublicKeyCredentialRequest], etc., then you should check if you
 * have any other library at interest that supports this custom [type] of credential request,
 * and if so use its parsing utilities to resolve to a type-safe class within that library.
 *
 * Note: The Bundle keys for [credentialData] and [candidateQueryData] should not be in the form
 * of androidx.credentials.*` as they are reserved for internal use by this androidx library.
 *
 * @property type the credential type determined by the credential-type-specific subclass for
 * custom use cases
 * @property credentialData the data of this [CreateCustomCredentialRequest] in the [Bundle]
 * format (note: bundle keys in the form of `androidx.credentials.*` are reserved for internal
 * library use)
 * @property candidateQueryData the partial request data in the [Bundle] format that will be sent
 * to the provider during the initial candidate query stage, which should not contain sensitive
 * user credential information (note: bundle keys in the form of `androidx.credentials.*` are
 * reserved for internal library use)
 * @property isSystemProviderRequired true if must only be fulfilled by a system provider and
 * false otherwise
 * @throws IllegalArgumentException If [type] is empty
 * @throws NullPointerException If [type], [credentialData], or [candidateQueryData] is null
