+/**
+ * `LoadingPageWidget` - Displays a loading screen while awaiting the result of a re-login attempt
+ * and redirects the user based on the result.
+ * 
+ * @remarks
+ * This widget is used to show a loading indicator while the app awaits the result of a re-login attempt.
+ * Once the result is available, it navigates to the appropriate screen:
+ * - If the re-login is successful, the user is redirected to the main app page.
+ * - If the re-login fails, the user is redirected to the splash screen.
+ * The widget ensures that any necessary updates, such as notifying listeners, are completed before navigating.
+ * 
+ * @param relogResult - The [Future<bool>] representing the result of the re-login operation.
+ *   - `true`: If the re-login attempt is successful, the user is redirected to the main page.
+ *   - `false`: If the re-login attempt fails, the user is redirected to the splash screen.
