ButtonStyle with shape or side params failed in flet 0.7.0

[david-shu]

example:

elevated-buttons example

failed in flet version 0.7.0.

maybe side and shape args in ButtonStyle not work.

My web app suddenly fails with this release. It is using some elevated buttons with ButtonStyle.

I have to go back to previous version for now which still works both locally and in fly.io.

This is the stack at the point of error.

This is the error text: App.on_error Invalid argument (index): "type"
