This thesis aims to describe accessibility problems encoutered on mobile user interfaces using the framework Flutter. Accessibility is the ability of a user to fully perceive, understand, navigate, and interact with digital content regardless from their capabilities. A brief introduction explain problems that users can encoutered today when they use their smartphones. First of all, we start from the guidelines defined in WCAG trying to the understand if they are sufficient or not, considering all categories of users, mainly focusing on users with disabilities. Then we integrate the WCAG guidelines with the new success criteria introduced with WCAG 2.1 and WCAG 2.2 and we define new guidelines for mobile that can help the end user. The thesis also showed how the framework Flutter addresses accessibility issues, proposing some new solutions. In conclusion, we define our results by trying to understand if the new mobile content accessibility guidelines are important and we analyze and understand how accessible the Flutter framework is for all categories of users.
