Flutter widget test scroll

WebIs there a way to detect if a widget is on screen/seen anywhere on the app. For example in a TabBar or a PageView. I already know that I could use the widget's build method to detect this, but this results in some really weird behavior where sometimes the widget has already been built and when the user navigates to the screen nothing happens. WebMy widget renders a list of photos and installs a ScrollController to detect when the user scrolls to the bottom so new photos can be loaded. On some devices however the initial loaded photos don't cover the whole screen. In this case I want to load more photos until the whole screen is covered. How can I achieve that?
