Following that, create the /screens directory mkdir src/features/sign-in/screens and the "sign in" screen touch src/features/sign-in/screens/SignInScreen.js. The "sign in" screen re-uses the , extending it to optionally support a custom submit button text. Note that if any error occurs, it'll be rendered using the component (full source code), which simply uses the component from native-base.

To being with, create the /components directory by running mkdir -p src/components and the email and password form touch src/components/EmailAndPasswordForm.js. The full code for the component can be found in the Github repository, but I'll highlight some of the important bits here.

The goal of this series of blog posts, is to provide a simple example of how to setup Expo and Firebase with email and password based authentication. When done, this app will support sign up, sign in, sign out, email verification, and password reset. All the code for this series of blog posts is available on this Github repository. Let's jump right in.

Additionally, there are more npm packages such as Formik and zod that come equipped with a range of features that can enhance the form validation process.

Formik

In the first part of this tutorial, we took a look at how to build React forms with custom HTML elements and form state and logic provided by Formik. In the second part, we switched to Formik components and build form with them. In this final part we will make another change, a small step back.
