PanelSnapping enum

Apply snapping effect to panel while opening / closing.

i.e., If the user is swiping the panel and leaves panel in any position between PanelState.closed and PanelState.expanded, it will be animated to the NEAREST PanelState.

For two-state panels, PanelState.collapsed is not used.

Values

disabled → const PanelSnapping

Don't snap the panel to the nearest position when user leaves the panel.

enabled → const PanelSnapping

Bring the panel to the nearest position when the user leaves the panel. More precisely, when user drags the panel in a direction and leaves, the panel moves to NEXT PanelState, which seems to be the nearest one to current position.

Note that, snap is ONLY applied, when dragging stops with a non-zero velocity. It means, if user stops dragging AFTER keeping panel idle under finger for one second, snapping will NOT be applied.

forced → const PanelSnapping

Same as enabled, but snapping is applied, even with zero dragging velocity. So, if user keeps the panel held for some time and then leaves, panel will still snap.
