How to Show a Loading Widget While Waiting for Google Sign-In in Flutter

When developing apps with Flutter, you might encounter situations where the user interface doesn't behave as smoothly as intended. A common scenario is during the Google Sign-In process, where users may experience brief moments of confusion—such as a black screen—before being redirected to their user information. This can detract from your app's user experience.

In this guide, we will guide you through the process of displaying a loading widget while your app waits for Google sign-in to complete, ensuring a seamless transition for your users.

Understanding the Problem

When users attempt to sign in with Google, they often see an unexpected black screen before getting to their personal information. This hiccup can cause anxiety, especially if users are unsure whether the app is still responding. To remedy this, we can display a loading widget to signal users that the app is processing their request.

Key Points:

Black screen transitions during sign-in are confusing and may lead to poor user experience.

A loading widget can provide visual feedback, assuring users that the process is ongoing.

Solution Overview

To solve this issue, we can follow a few simple steps to integrate a loading widget into the Google sign-in process. The plan is to display the loading widget when the sign-in button is pressed and to hide it once the sign-in process is complete.

Steps to Implement the Loading Widget

Create Loading Methods:
First, we need to define two methods: one for displaying the loading widget and another for hiding it after the sign-in process completes.

Modify the Login Button Logic:
Next, we update the onPressed method in our LoginButton widget to show the loading dialog when the button is clicked.

By implementing these changes, the loading widget will appear as soon as the user clicks the sign-in button, providing immediate visual feedback.
