dismissThresholds property Null safety
final
The offset threshold the item has to be dragged in order to be considered dismissed.
Represented as a fraction, e.g. if it is 0.4 (the default), then the item has to be dragged at least 40% towards one direction to be considered dismissed. Clients can define different thresholds for each dismiss direction.
Flinging is treated as being equivalent to dragging almost to 1.0, so flinging can dismiss an item past any threshold less than 1.0.
Setting a threshold of 1.0 (or greater) prevents a drag in the given
DismissDirection
even if it would be allowed by the direction
property.
