Onboarding and Sign In

Overview

A Flutter app focused on the first minutes of a user's experience: an onboarding that introduces the product, followed by a sign-in screen with clear validation. These two flows appear in almost every app, so getting them right is worth practicing on their own.

What the app does

• Onboarding presentation introducing the app and its main features.
• Navigation to sign in once onboarding is complete.
• Field validation on email and password:
  • valid email format;
  • password requirements;
  • clear error messages pointing to what needs fixing.

Technical decisions

• Built with plain Flutter and no extra dependencies, to keep the focus on layout, navigation and validation logic.
• Written following Clean Code principles, with a user-friendly design as a goal from the start.
