CustomProgressDialog Widget Not Handling Internet Connectivity Properly

[may-tas]

Describe the bug

• The CustomProgressDialog widget does not correctly handle internet connectivity. It always displays the CupertinoActivityIndicator, even when there is no internet connection. According to the documentation, it should show a "No Internet" image and text when offline.

To Reproduce
Steps to reproduce the behavior:

1.Run the app with an active internet connection.
2.After logging in to the app, try creating an event normally.
3.Now turn off the internet connection and try creating an event.
3.Notice that the loading indicator still appears instead of the expected "No Internet" UI.
4.Compare it with the intended behavior in the documentation.

Expected behavior
When there is no internet connection, the CustomProgressDialog widget should display:

• A "No Internet" image
• A message saying "No Internet"

Actual behavior

• The widget always shows the CupertinoActivityIndicator, regardless of connectivity status.

Screenshots

Screenshot 2: Expected implementation as per documentation

Additional details

• We just have to add the correct implementation according to the documentation using the connectivity check (model.connectivityPresent).
