Overflow when adding anything to Header

[murphycrosby]

Had to not use the Header component, but put everything in a stack.

upperLayer: Stack(
  children: <Widget>[
    Container(
      height: 69.0,
      child: ListView.builder(
          physics: NeverScrollableScrollPhysics(),
          itemCount: 1,
          itemBuilder: (BuildContext context, int index) {
            return _getHeaderLayer();
          }
      ),
    ),
    Transform.translate(
      offset: Offset(0, 69.0),
      child: _getUpperLayer(state),
    ),
  ]
),

Following your suggestion, It should be fixed now.
The bottom sheet also accepts a new parameter called headerHeight, in the future I'll try to find a way to automatically detect the height of the header
