sqflite_sqlcipher: ^2.0.0

This may be a problem with sqlcipher. Quite a lot, I just copied part of it.

Do you get a crash at the end, or are those "just" warnings? The warnings are generated by the official SqlCipher native library which it is outside this repository. This package is just a wrapper around that library, so I cannot do anything about it. Unfortunately one has to live with those warnings...

These are just warnings and did not crash my app, but there are a lot of warnings, with more than 120 repeated warnings. If there is no way to solve it, it can only be so.

@HeebeLee Yes, as far as I know, we cannot do anything about it here. I don't know if there are ways to ignore warnings for certain libraries when compiling.
