alreadyConsumed property
Whether this token was already consumed.
If this is the first time this method has seen the given App Check token,
this field will be omitted from the response. The given token will then be
marked as already_consumed (set to true) for all future invocations of
this method for that token. Note that if the given App Check token is
invalid, an HTTP 403 error is returned instead of a response containing
this field, regardless whether the token was already consumed.
Implementation
core.bool? alreadyConsumed;
