Rectangle<T extends num> constructor
- T left,
- T top,
- T width,
- T height
Create a rectangle spanned by (left, top) and
(left+width, top+height).
The rectangle contains the points
with x-coordinate between left and left + width, and
with y-coordinate between top and top + height, both inclusive.
The width and height should be non-negative.
If width or height are negative, they are clamped to zero.
If width and height are zero, the "rectangle" comprises only the
single point (left, top).
Example:
var rectangle = const Rectangle(20, 50, 300, 600);
print(rectangle.left); // 20
print(rectangle.top); // 50
print(rectangle.right); // 320
print(rectangle.bottom); // 650
