There's nothing in the documentation that would indicate steps required to make this work with some changes. But I tried updating to gradle 8.7 in gradle-wrapper.properties and it still errors.

Also there is no such thing as android tools 8.7, 8.4 is the latest.

I was able to sort of get around this be going into the package cache for this library and adding this to the build.gradle:

namespace "dev.dint.cryptography_flutter"

That eliminated the error. There are TONS of depreciation warnings though from this library.

Also need to remove package property in AndroidManifest.xml
