Example app doesn't work

[12people]

The example app is using an outdated Flutter version as well as updated libraries and doesn't build with the latest Flutter version out of the box.

I am using it in an App, I like so much this lib, I hope that anyone can continue developer it. I use Flutter 3.16.5

Hi @12people, @rodrideveloper,
I confirmed that PR:#117 works well on my Android phone (Google Pixel6a) with Flutter 3.22.1.
If you have iOS, please try PR:#125 also.
