How widespread are Actionscript3 naming conventions?

In 90% of the example projects I see for ActionScript / Flex I notice the 开发者_开发百科following two coding conventions:

1) private member variables with getters/setters start with an underscore as in "_credentials"

and

2) interfaces start with the letter "I" as in "ISessionInfo"

Coming from the Java world, I find both of these conventions unnecessary and annoying. I am about to start a new Flex project and was planning on NOT following these conventions unless they are truly are widespread, standard conventions in the Actionscript/Flex world.

Those conventions are used wherever I've been involved with ActionScript, but you are certainly free to do what works for you, your team, or your company.
