Hi asep,
Thanks for contacting Syncfusion support.
This is the behavior in Flutter framework itself when you use nested scroll views. The horizontal scrollbar can be viewed only when the vertical scrollbar is fully scrolled to its maximum offset. We have logged issue report in framework to show both the scrollbars always. They have already considered as feature.
