App crashed when package is used on iOS 18

Hi everyone,

I am facing this bug when running my flutter code on iOS. The app crashed only when I use my flutter_pdfview package. The app is able to be built but just crashed when that package is used.

Only happened to iOS 18

Tried looking for answers online but found none close to what I am experiencing. Hypothesis is something to do with the package.

Hope to get any insights. Thanks!
