Custom preview screen when swiping between apps

[tigrenok00]

Hi,
Can we control the UI of the preview screen that will be shown at secured/locked state when swiping between apps? It currently shows white blank screen for me. But I know other apps that set a custom screen in this case. I'm using a lockedBuilder with custom UI but this is not what is shown when swiping between apps (tested on android for now).

Because of the lifecycle of android Flutter does not have the time to render a new view when going to app switcher.
