我能够通过制作一个对象并使用该对象来解决这个问题。

 // add a local variable to store navCtrl object
        let thatNavCtrl = this.navCtrl;
        window.FirebasePlugin.verifyPhoneNumber(phoneNumber, 60, function (credential) {
            let verificationId = credential.verificationId;
            thatNavCtrl.push(AuthDeviceVerifyPage, { verificationid: verificationId });

        }, (error) => {
              console.error(error);
        });

    }
