I hope to solve this error because most of the applications that I work on are giving the same or similar error

I tried downgrading the sdk to a lower level but it gives the same error

" The current Dart SDK version is 2.19.0-146.2.beta. Because movies_booking requires SDK version >=3.0.0 <4.0.0, version solving failed "

The app was working fine and after the latest update to flutter it is giving this error

    You need to check what version you have of Flutter and Dart and use the right one in the code. check [this answer](https://stackoverflow.com/a/73426677/13058371) ... Also, always make sure to use packages where their creator keeps the package up-to-date, that would be better, I am saying this just cause I didn't find it on `pub.dev` – Remoo Jun 14 '23 at 07:06
