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.
Implementing the “Remember Me” Functionality
To add the “Remember Me” functionality to your login page in Flutter, follow these steps:
- Create a boolean variable, let’s call it
rememberMe
, and set its initial value tofalse

rememberMe
variable. - When the user taps on the checkbox, update the value of
rememberMe
accordingly. - When the user submits the login form, check the value of
rememberMe
. If it’strue
, securely store the login credentials locally on the device using a secure storage plugin like flutter_secure_storage. - Upon launching the app, retrieve the stored credentials from the secure storage and prepopulate the login fields if

By following these steps, you can easily add the “Remember Me” functionality to your login page in Flutter. Remember to handle any potential security concerns, such as encrypting the stored credentials and protecting them against unauthorized access.
