FlashMode

Kotlin |Java

class FlashMode

androidx.camera.core.FlashMode

The flash mode options when taking a picture using ImageCapture.

Applications can check if there is a flash unit via CameraInfo#hasFlashUnit() and update UI component if necessary. If there is no flash unit, then the FlashMode set to ImageCapture#setFlashMode(int) will take no effect for the subsequent photo capture requests and they will act like FlashMode#OFF.

When the torch is enabled via CameraControl#enableTorch(boolean), the torch will remain enabled during photo capture regardless of flash mode setting. When the torch is disabled, flash will function as specified by ImageCapture#setFlashMode(int).
