The project has one source file, FlashLightU.pas, which contains the main form class.
TFlashLightForm represents the main form of the application. It contains the following components:
- The main form contains two TImage objects: ImageOff and ImageOn that are shown or hidden depending on whether the flash is active.
- The flashlight and the light on the screen are also two TImage objects on which two effects are applied: TGlowEffect and TShadowEffect.
