Flutter is a versatile framework that allows developers to build beautiful and efficient mobile applications. One essential feature of any login page is the “Remember Me” option, which allows users to stay logged in even after they close the app. In this article, I will guide you through the process of adding the “Remember Me” functionality to a login page in Flutter, sharing my personal experience and insights along the way.
Understanding the “Remember Me” Feature
Before we dive into the implementation details, let’s take a moment to understand the “Remember Me” feature. The purpose of this feature is to provide convenience to users by allowing them to save their login credentials, such as username and password, so they don’t have to re-enter them every time they open the app.
When a user selects the “Remember Me” option, the app securely stores their login credentials locally on the device. The next time the user opens the app, the stored credentials are retrieved and automatically populated in the login fields, saving valuable time and effort.
