To have access to the latest features, bug fixes, and performance improvements, it's important to keep your FlutterFlow version up to date. In this article, we'll guide you through the process of upgrading to the latest version of FlutterFlow.

The first step in upgrading to the latest version of FlutterFlow is to refresh the application. To do this, follow these steps:

If you're using Windows, press the "Ctrl" and "R" keys simultaneously (Ctrl + R).

If you're using a Mac, press the "Command" and "R" keys simultaneously (Cmd + R).

This action will trigger FlutterFlow to check for any available updates and download the latest version.

After refreshing FlutterFlow, it's crucial to clear your browser cache. This ensures that any outdated files or data are removed, allowing the latest version of FlutterFlow to run smoothly. The process of clearing your browser cache may vary depending on the browser you're using

If you encounter an error in FlutterFlow related to insufficient permissions for the firebase@flutterflow.io account, follow these steps to resolve the issue:
