GPoint class

The GPoint object represents a location in a two-dimensional coordinate system, where x represents the horizontal axis and y represents the vertical axis.

The following code creates a point at (0,0):

final myPoint = GPoint();

Constructors

GPoint([double x = 0, double y = 0]): Creates a new GPoint instance with the specified x and y coordinates.

Methods

add(GPoint point) → GPoint: Adds the coordinates of another point to the coordinates of this point and returns the result as a new point.
clone() → GPoint: Creates a copy of this GPoint object.
equals(GPoint point) → bool: Checks if this GPoint is equal to another GPoint by comparing their x and y coordinates. Returns true if they are equal, otherwise false.
multiply([double dx = 1, double dy = 1]) → void: Multiply the coordinates of this GPoint by given dx and dy values.
normalize(double thickness) → void: === Mutators === The following methods modify the current point. Normalizes the GPoint to have the specified thickness but keeping its direction.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
offset(double dx, double dy) → void: Offsets this point's coordinates by dx along the x-axis and by dy along the y-axis.
setEmpty() → GPoint: Sets the x and y values of this point to zero.
setTo(double x, double y) → GPoint: Sets the x and y values of this GPoint to the provided x and y values respectively.
subtract(GPoint point) → GPoint: Subtracts the coordinates of another point from the coordinates of this point to create a new point.
toNative() → Offset: Creates a Dart Offset instance from this GPoint.
toString() → String: Returns a string that contains the values of the x and y coordinates.
override

Operators

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

Static Methods

distance(GPoint p1, GPoint p2) → double: Returns the distance between p1 and p2.
fromNative(Offset nativeOffset) → GPoint: Creates a point instance from an dart Offset.
interpolate(GPoint a, GPoint b, double f) → GPoint: Returns the point that is at the position specified by the interpolation factor f between points a and b.
polar(double length, double angle) → GPoint: Returns a new GPoint object in polar coordinates based on a length and an angle.
