A: Are "strong passwords" at all meaningful? Disclaimer: I am not a security expert nor a security professional. There is, of course, a relevant XKCD comic for this: XKCD comic about how short passwords with special symbols and numbers are less secure and harder to remember than long passwords with only alphabetic characters The entrop...

I do not like the speed of SQLite or the fact that it does not enforce column datatypes and want to use something like PostgreSQL or MySQL with my desktop app. Is there a way to do this in Flutter that doesn't r...
