ExpandedTileController class
A controller for ExpandedTile.
An ExpandedTileController would let you control programatically the expansion state of an ExpandedTile widget.
If you are going to use in a ListView builder, assign a controller constructor 'ExpandedTileController()' not an initialized one.
