Checkout QCameraFlashControl

Specifically call setFlashMode with QCameraExposure::FlashTorch.

To get the current flash mode use

QCamera* camera = new QCamera; QCameraExposure* cameraExposure = camera.exposure();

FlashModes flashMode = cameraExposure->flashMode();

To set a flash mode (for example always on) use

QCamera* camera = new QCamera; QCameraExposure* cameraExposure = camera.exposure();

cameraExposure->setFlashMode(QCameraExposure::FlashTorch);
