Using custom States #

All user interface can be customized through custom States, including:

  • CameraPickerState
  • CameraPickerViewerState

After override States, pass them through the picking method, more specifically:

  • CameraPicker.pickFromCamera(createPickerState: () => CustomCameraPickerState());
  • CameraPickerViewer.pushToViewer(..., createViewerState: () => CustomCameraPickerViewerState());

Frequently asked question 💭 #
