Scrolling thumb height depends on currently visible position inside ScrollView. The longer ScrollView content height is, the shorter thumb height will be. You can't set it manually, moreover I don't see any reason to do it.

@Mol0ko What if designers require this? Why are you denying the motivation for this question? I need this, because it is specifically required in my current design document. I'll try to make a workaround and post it here. My idea is to create two `ScrollControllers` that manipulate each other, but are displayed in different Widgets.
