Fixed the problem that the initial 'pdf' is not displayed in the 'android 12' version. It was a problem with `sync`. But still pdf doesn't change in `release`.

Starting from version 12, the check for `sha256_cert_fingerprints ` values ​​has been strengthened. Check if the `sha256_cert_fingerprints` value in the `assetlinks.json` file is correct.

Using the key value solves it, but this does not apply in release. can you help me with this issue?

I'm having the same problem. The first load of the pdf and the load of the new pdf incrementally increases the memory. Did you ever solve the problem?
