Translate other elements on DraggableScrollableSheet top-bottom movement

Hi I have to translate two of my widgets based on the DraggableScrollableSheet drag position (you can think this bottom sheet as in GMaps). The widgets I have to move/animates are:

• Text - It needs to translate & scale back-and-forth and in-out respectively following an arc path simultaneously. (See expected video)
• Row - It needs to translate a bit and then out. Again back-and-forth.

Trails -

• Text widget scaling in-out properly but translating in some weird way. (See actual video)

• Row widget is fading in-out fine, but having a hard time translating it.

Code -

  final Duration _animationDuration = const Duration(milliseconds: 300);
  bool _isNavShown = true;
  double yValue = -35.0;
  void _applyEffectsOnDrag(double factor) {
    print(factor);
    if (factor > 0.7) {
      _isNavShown = false;
    } else {
      _isNavShown = true;
    }
  }

  Widget _getNavigationButtons(BuildContext ctx, bool isHidden) {
    return Padding(
      padding: verticalAndHorizontailPadding,
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: [
          ...[1, 2, 3]
              .map(
                (e) => Container(
                  decoration: CircleStyles.navButton,
                  child: Column(
                    crossAxisAlignment: CrossAxisAlignment.center,

                    ],
                  ),
                ),
