AppVisibilityManager class

A widget that manages the visibility of its child based on the app's lifecycle state.

The AppVisibilityManager listens to the app's lifecycle changes and updates the visibility of the child widget accordingly. When the app is inactive or paused, the child widget is hidden, and a custom image is displayed. When the app resumes, the child widget is shown again.

The child parameter is the main widget that will be managed, and the image parameter is the widget that will be displayed when the child is hidden.
