The QCameraFlashControl class allows controlling a camera's flash.
You can set the type of flash effect used when an image is captured, and test to see if the flash hardware is ready to fire.
You can retrieve this control from the camera object in the usual way:
Some camera devices may not have flash hardware, or may not be configurable. In that case, there will be no QCameraFlashControl available.
The interface name of QCameraFlashControl is org.qt-project.qt.cameraflashcontrol/5.0 as defined in QCameraFlashControl_iid.

[protected] QCameraFlashControl::QCameraFlashControl(QObject *parent = nullptr)Constructs a camera flash control object with parent.
[virtual] QCameraFlashControl::~QCameraFlashControl()Destroys the camera control object.
[pure virtual] QCameraExposure::FlashModes
QCameraFlashControl::flashMode() constReturns the current flash mode.
See also setFlashMode().
[signal] void QCameraFlashControl::flashReady(bool
ready)Signal emitted when flash state changes to ready.
[pure virtual] bool QCameraFlashControl::isFlashModeSupported(QCameraExposure::FlashModes mode) constReturn true if the reqested flash mode is supported. Some QCameraExposure::FlashMode values can be combined, for example QCameraExposure::FlashManual | QCameraExposure::FlashSlowSyncRearCurtain
[pure virtual] bool QCameraFlashControl::isFlashReady() constReturns true if flash is charged.
[pure virtual] void QCameraFlashControl::setFlashMode(QCameraExposure::FlashModes mode)Set the current flash mode.
Usually a single QCameraExposure::FlashMode flag is used, but some non conflicting flags combination are also allowed, like QCameraExposure::FlashManual | QCameraExposure::FlashSlowSyncRearCurtain.
See also flashMode().
