[abbashosseinii]

The app crashes on iOS devices due to exceeding the memory limit (1450 MB). The crash occurs in the pdfrx package when processing large files. Android works fine, but iOS fails with the following error:

* thread #35, name = 'DartWorker', stop reason = EXC_RESOURCE (RESOURCE_TYPE_MEMORY: high watermark memory limit exceeded) (limit=1450 MB)

Lost connection to device.

Steps to Reproduce:
