Flash-console is a debugger/logger for flash, flex and AIR. It runs in the same flash you want to use logging on or use remoting to print logs on a flash remote (running on AIR / EXE / swf / swf in html – your choice).
The main advantage of console is that you can password protect and hide the console during beta / user testing stage of your flash project. This gives developers the ability to go into console on-site and see the traces. No special browser or player version is required to use. Console gives you access to flash objects and properties via commandLine, so narrowing down bugs, manipulating properties and variables can be very easy. Console can also track objects to see if they have been garbage collected during run time.
