You can't do that directly. The tune editor will only apply to the background image. If you need this functionality, you can create a custom solution by using the ColorFilterGenerator widget from the image editor and wrapping your layer inside it. Here’s an example:

ColorFilterGenerator(
  filters: [],
  tuneAdjustments: [
    TuneAdjustmentMatrix(
      id: 'brightness',
      matrix: ColorFilterAddons.brightness(0.4),
      value: 0.4,
    ),
  ],
  child: YOUR_WIDGET,
  )
