Today, I finalize the sign-up process. I'll be improving the user experience in these ways:

1. Separate the onboarding screens and the signup screens. The user will be able to view three onboarding screens and undergo a step-by-step registration process. I also added a skip button on the onboarding screens whereby the user can click on it and skip to the step-by-step registration process.

2. Get rid of the progress dots and replace them with "Step 1/3" statements at the top-right corner of the screen.

New Onboarding Screens

I simply included text in the three sliding screens. Each screen describes a feature of the app. On the final screen, there is a get started button which takes the user to the signup page using react native navigation: - the same code is used for the skip button which is on every onboarding screen.

<TouchableOpacity style={styles.button} onPress {()=>navigation.replace("signup") }>
          <LongButton text="Get Started" />
</TouchableOpacity>

The Signup Page

The signup page displays the different screens and their inputs conditionally. I used three boolean variables to conditionally render the screens. The boolean variables include stepOne, stepTwo, stepThree. Initially, only stepOne is true while the rest are false. Each screen is only displayed if its respective step variable is true. If the validation check for a screen is correct, the current step is set to false and the next step is set to true. Additionally, I declare and initialize all the input variables, their set functions, the error messages and their set functions on the signup page. These variables are then passed on to the respective screens.

Signup.js

import { Text, View, StyleSheet, Dimensions } from "react-native";
import SignUpOne from "./SignUpOne";
import SignUpTwo from "./SignUpTwo";
import SignUpThree from "./SignUpThree";
import React from "react";

export default function SignUp({ navigation }) {
  //initiliaze formdata variables
  const [email, setEmail] = React.useState("");
  const [fullName, setFullName] = React.useState("");
  const [password, setPassword] = React.useState("");
  const [confirmPass, setConfirmPass] = React.useState("");
  //initialise error messages
  const [emailErr, setEmailErr] = React.useState(null);
  const [fullNameErr, setFullNameErr] = React.useState(null);
  const [passwordErr, setPasswordErr] = React.useState(null);
  const [confirmPassErr, setConfirmPassErr] = React.useState(null);
  //initialise conditional rendering variables
  const [stepOne, setStepOne] = React.useState(true);
  const [stepTwo, setStepTwo] = React.useState(false);
  const [stepThree, setStepThree] = React.useState(false);
  const [step, setStep] = React.useState(1);

  return (

SignupThree.js

• I use secureTextEntry on the inputs to hide the passwords as the user types.

• I have also included an eye icon button where the user can toggle the password's visibility.

• If the passwords are valid, user is taken to the temporary home page. I use navigation.replace so that the user is restrained from going back to the signup pages.
