Streching rectangle

[Basavaraj-PN]

rectangle is not properly stretching, can anyone explain?

def lerp(a,  b, t) -> float:
    return a + (b - a) * t

class StretchRectangle(Scene):
    def construct(self):

        rectangle = Rectangle()
        self.add(rectangle)  # Add the rectangle to the scene

        t = ValueTracker(0)

        def lerp_updater(rec):
            t_ = t.get_value()
            v = lerp(-2, 2, t_)
            rec.stretch_about_point(v, 0, rec.get_left())

        rectangle.add_updater(lerp_updater)
        self.play(
            t.animate.set_value(1),
            run_time=8,
            rate_func=smooth,
        )
        self.wait(1)  # Wait for 1 second at the end
