Values

latestPointer → const MultitouchDragStrategy

Only the latest active pointer is tracked by the recognizer.

If the tracked pointer is released, the latest of the remaining active pointers will continue to be tracked.

This is the behavior typically seen on Android.

sumAllPointers → const MultitouchDragStrategy

All active pointers will be tracked together. The scrolling offset is the sum of the offsets of all active pointers.

When a Scrollable drives scrolling by this drag strategy, the scrolling speed will double or triple, depending on how many fingers are dragging at the same time.
