Designing the Sign-Up Page for the Flutter Ecommerce App

In this section, we will shift our focus to designing the sign-up page for our Flutter ecommerce app. The sign-up page allows new users to create an account and join the platform. We’ll create a user-friendly sign-up page with input fields for personal info, email, password, and a sign-up button for a seamless experience. Additionally, we may include optional fields for additional details or preferences. Following the principles of responsive design, we will ensure that the page layout adapts seamlessly to various screen sizes. Crafting an enticing, efficient sign-up page, our aim is to provide new users with a seamless onboarding  experience. Let’s proceed with designing the sign-up page to facilitate user registration and engagement in our app.
