Making progress (bars) with Slides Add-ons

Google Slides Add-ons have been introduced to allow developers to enhance the functionality of Google Slides by integrating features from their own applications, with possibilities extending to other Google apps like Docs, Sheets, and Gmail. One innovative use case demonstrated by G Suite Developer Advocate Wesley Chun and Engineer Grant Timmerman involves creating progress bars within presentations using Google Apps Script. This add-on enables users to display or hide progress bars, represented as rectangles at the bottom of slide pages, providing a visual indication of progress during presentations. The implementation involves a script that calculates the completion ratio and adjusts the rectangle size accordingly, showcasing the potential of Apps Script to transform and automate Google Slides functionalities. For those interested in exploring further, resources such as the Google Slides Add-on Quickstart and additional examples of programmatic access to Google Slides are available, offering a gateway to developing various add-ons through Apps Script.
