@NonNull abstract fun filter(@NonNull cameraInfos: MutableList<CameraInfo!>): MutableList<CameraInfo!>
Filters a list of CameraInfos and returns those matching the requirements.
If the output list contains CameraInfos not in the input list, when used by a androidx.camera.core.CameraSelector then it will result in an IllegalArgumentException thrown when calling bindToLifecycle.
The CameraInfo that has lower index in the list has higher priority. When used by androidx.camera.core.CameraSelector.Builder#addCameraFilter(CameraFilter), the available cameras will be filtered by all CameraFilters by the order they were added. The first camera in the result will be selected if there are multiple cameras left.

| Return | |

MutableList<CameraInfo!> |
The output list of CameraInfos that match the requirements. Users are expected to create a new list to return with. |
