i have a scaling animation whenever the below widget initialises. it’s working fine but i would want the scaling to start from the top left instead of the center, kind of like an “revealing” animation. i have tried using align (to top left) but it doesnt work. also, the below widget is a child of a stack. tia for all inputs

late final AnimationController _scaleController = AnimationController(
    duration: const Duration(seconds: 1),
    vsync: this,
  );

ScaleTransition(
      scale: _scaleAnimation,
      child: Scaffold(
        body: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text(
              'Hi'
            ),
            
          ],
        ),
      ),
    );
