ViewportTransform class



ViewportTransform(Vector2 extents, Vector2 center, double scale)


center Vector2
center of the viewport.
extents Vector2
This is the half-width and half-height. This should be the actual half-width and half-height, not anything transformed or scaled.
hashCode int
The hash code for this object.
no setterinherited
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
scale double
Returns the scaling factor used in converting from world sizes to rendering sizes.
getter/setter pair
translation Vector2
The current translation is the difference in canvas units between the actual center of the canvas and the currently specified center. For example, if the actual canvas center is (5, 5) but the current center is (6, 6), the translation is (1, 1).
getter/setter pair
yFlip bool
if we flip the y axis when transforming.
getter/setter pair


noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
screenToWorld(Vector2 argScreen) Vector2
Takes the screen coordinates and return the corresponding world coordinates.
setCamera(double x, double y, double s) → void
Sets the transform's center to the given x and y coordinates, and using the given scale.
toString() String
A string representation of this object.
worldToScreen(Vector2 argWorld) Vector2
Takes the world coordinates and return the corresponding screen coordinates.


operator ==(Object other) bool
The equality operator.
