fl.controls namespace is a part of Flash Pro.

To integrate with Flash Builder, you can either add the package by SWC or via code:

Adding Flash Components to Flash Builder:

Adding by SWC:

• Right-click on your project in Flash Builder, and go to Properties.
• Select “ActionScript Build Path” from the left.
• Go to the “Libary path” tab now available on the right.
• Click “Add SWC…”
• Add libs from Flash such as flash.swc or IK, depending on what version of the Flash IDE you have and where you installed it.

Windows:
C:\Program Files (x86)\Adobe\Adobe Flash CS5.5\Common\Configuration\ActionScript 3.0\libs\flash.swc

Mac OS X:
/Applications/Adobe Flash CS5/Common/Configuration/ActionScript 3.0/libs/flash.swc

Adding by source folder:

• Right-click on your project in Flash Builder, and go to Properties.
• Select “ActionScript Build Path” from the left.
• Go to the “Source path” tab now available on the right.
• Click “Add Folder…”
  The Flash components should be in a location with a path similar to the following, depending on what version of the Flash IDE you have and where you installed it.

Windows:
C:\Program Files (x86)\Adobe\Adobe Flash CS5.5\Common\Configuration\Component Source\ActionScript 3.0\User Interface

Mac OS X:
/Applications/Adobe Flash CS5.5/Common/Configuration/Component Source/ActionScript 3.0/User Interface
