                        .setName(validator.from(et_name))
                        .setAge(validator.from(et_name))
                        .setMobile(validator.from(et_name))
                        .setArea(validator.from(et_name)))
                .doIfInvalid(() -> toast("Fill required data."))
                .asObservable()
                .doOnNext(data -> toast("Saving Client info"))
//               .flatMap(data -> {}) --> save in database
//               .flatMap(data -> {}) --> send to server
                .subscribe(

                .emptyMessage("Field is empty.")
                .asObservable()
                .doOnNext(data -> Log.d(getClass().getSimpleName(), "Saving Client info"))
//               .flatMap(data -> {}) --> save in database
//               .flatMap(data -> {}) --> send to server
