Debug/Release behavior on Flutter 1.5.4

[alextekartik]

Thanks for your plugin that I use as a way to encode a database as an example in sembast.

After some tests, I found that indeed xxtea gives different results on debug and release!

xxtea.encryptToString('value', 'test')

When used in current Flutter stable, it gives NMvXe7aiJfgaFlsx on debug and something different (randomly) on release (but that could be possible in some encryption algorithm but I think not here). But it also cannot decrypt the debug value:

xxtea.decryptToString('NMvXe7aiJfgaFlsx', 'test')

gives something different each time ('Falue', '\nalue'...) where the first letter is messed up.

According to a user, it was working fine on Flutter 1.2.1.
