How Do You Develop Flex Applications?

Flex is mainly used to create highly interactive and rich web applications which are supported on any browser. And, those Flex Applications are delivered on the web via the Flash Player and to the desktop via Adobe Air.

What do you need to develop Flex Applications?

• Flex Software Development Kit (SDK)
• Knowledge of Action Script 3 and MXML
• Flex builder IDE (However, it’s not compulsory)
• Blaze Data Services or LiveCycle Data Services
• Flash Player
  

You can develop Flex Applications using MXML and Action Script 3. And, following are some basic steps which you can follow to develop applications:

• Define an application interface using a set of pre-defined components (forms, buttons, and so on)
• Arrange components into a user interface design
• Use styles and themes to define the visual design
• Add dynamic behavior (one part of the application interacting with another, for example)
• Define and connect to data services as needed
• Build the source code into an SWF file that runs in the Flash Player
  

Once you done with Flex Application Development, you need to test your applications. You run the application using compiler in the SDK into SWF. If you get any error you can use debugging tool like Flex Builder Debugger. Debugging tools are used to set and manage breakpoints in your code; control application execution by suspending, resuming, and terminating the application, and so on.

Using Flex Technology you can develop and deliver highly expressive, high performance, rich and interactive web applications.
