Enum UserScroll 

pub enum UserScroll {
    WhenOverflowing,
    Always,
    Never,
}

Whether the user may scroll an area (milestone 649): the reference’s AlwaysScrollableScrollPhysics and NeverScrollableScrollPhysics, and the rule they both override.

Whatever it says, the application still moves the area: a controller’s jump, a “bring this into view”, a page turned in code. This is about the user’s drag, fling and wheel only.

Variants

WhenOverflowing

When there is content outside the viewport to reveal, or a pull to refresh above — the reference’s default rule.

Always

Always, even with everything in sight: a short list still bounces, and still takes the drag from the area around it.

Never

Never: the drag, the fling and the wheel go to the area around it, as if it were not a scrollable at all.
