I think you are looking for ExpansionTile widget. This takes a title property which is equivalent to header and children property to which you can pass widgets to be shown or hidden on toggle. You can find an example of how to use it here.

Simple Example Usage:

new ExpansionTile(title: new Text("Numbers"),
      children: [
        new Text("Number: 1"),
        new Text("Number: 2"),
        new Text("Number: 3"),
        new Text("Number: 4"),
        new Text("Number: 5")
      ],
),

Hope that helps!
