Installation

Add the following line to pubspec.yaml:

dependencies:
  draggable_home: ^1.0.0

Basic setup

DraggableHome requires you to provide title, headerWidget and body:

• title widget is basically for title in AppBar. For no title in appbar, simply put an empty Contnainer.
• headerWidget is the expanded widget just above body when not fully expanded.
• body is in the form of Column which requires list of widget or a widget. Do not add any verically scrollable widge or you may just disable the scroll.

  physics: const NeverScrollableScrollPhysics()

Sample code

DraggableHome(
  title: Text("Ttitle"),
  headerWidget: headerWidget(),
  body: [
    Container(...),
    (...),
  ]
);

  body: [
    Container(...),

    // shrinkWrap true required for ListView.builder()
    // disable the scroll for any verically scrollable widget
    ListView.builder(
      physics: NeverScrollableScrollPhysics(),
      shrinkWrap: true,
      itemCount: list.length,
      itemBuilder: (context, index) => Card(
