Taking Picture

Taking picture

it's very simple to take pictures with Camposer, there are some methods to save with CameraState:

• ContentValues + MediaStore
• File
• ImageCapture.OutputFileOptions

All of these options use the method CameraState.takePicture, which has the last parameter: the callback with image capture result, if successful, it contains the saved URI.

Here is an example using the file:

val cameraState = rememberCameraState()
val context = LocalContext.current
CameraPreview(
  cameraState = cameraState,
) {
  Box(
    onClick = { 
      cameraState.takePicture(file) { result -> 
        if (result is ImageCaptureResult.Success) { // result.savedUri might be useful to you
          Toast.makeText(context, "Success!", Toast.LENGTH_LONG).show()
        }
      } 
    }
  ) {
    Text(text = "Take picture")
  }
}

There's also support to suspend functions! Using suspend functions TakePicture it's return savedUri or throw throwable, so be careful when used it.
