What are the alternatives of Flex builder for flex development (Free ware, open source preferred). I know one that is FlashDevelop, but it is not matured/full fledged flex IDE.
Actually FlashDevelop is the only open-source solution. The other solutions are:
- IntelliJ IDEA
- SapphireSteel (a plugin for VisualStudio, they have a free Personal edition)
- FDT (primarily ActionScipt IDE, but seems they have some support for MXML too.)
Eclipse with Flex Builder plugin. While Flex Builder is based on Eclipse, I prefer the former because I often find myself programming in other languages also (namely Java). That and the fact that I never managed to make subclipse plugin to work on Flex Builder and the showing of .svn directories in the Navigator view annoyed me to no end.
Actually, FlashDevelop is quite mature. I like to work in it, and since Flex is a text-only language (XML and AS), it's easy to write it in a text editor. Furthermore, FD has support for Flash / Flex like code completion, etc.
Google how to set up FD with flex.
Alternatively, you can also download the monster file that is the Flex Builder 3 installer. The 60 day trial is longer than it seems, and it costs nothing compared to Flash studio or Dreamweaver.
Or you can arrange your company to buy it for you:-) I did.
Actually there's an open-source alternative: AXDT: open-source cross-platform alternative for Flash development
It's not a competitor to Flash Builder or FDT (that I think is the best IDE out there), but it makes a good setup for small things or for those just starting to develop for Flash Platform.
