getFollowerConstraints abstract method
BoxConstraints
getFollowerConstraints({
- required Size targetSize,
- required BoxConstraints theaterConstraints,
Returns the layout constraints that are given to the follower element.
The targetSize
represents the bounds of the element which the follower
element should be anchored to. This must be the same value that is passed
to getFollowerOffset. No assumptions should be made about the coordinate
space, i.e. only the size of the target should be considered.
The theaterConstraints
represent the full available space to place the
follower element in. This is irrespective of where the target is
positioned within the full available space.
Implementation
BoxConstraints getFollowerConstraints({
required Size targetSize,
required BoxConstraints theaterConstraints,
});
