generic_dropdown_widget 2.1.0

A generic dropdown for flutter. Enables displaying arbitrary content with an arbitrary toggle anywhere in the app.

Generic Dropdown Widget

The generic dropdown Flutter widget is a customizable component that allows users to toggle between two states: a closed state and an open state, revealing content. This widget is designed to support arbitrary toggle and content widgets. Developers can define their own widgets to be used as the toggle button and the content within the dropdown.

Head over to the storybook to see it in action. (Much love to storybook_flutter at this point!)

Usage

Import the package and then use the GenericDropdown widget. The widget itself is well documented, so there is not much need of explaining it here. The following example shows how to use the dropdown with two simple containers:

// imports and stuff.

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) => GenericDropdown(
      toggleBuilder: (context, isOpen) => Container(
        height: 50,
        width: 50,
        color: isOpen ? Colors.green : Colors.red,
      ),
      contentBuilder: (context, repaint, close) => Container(
        height: 100,
        width: 100,
        color: Colors.blue,
      ),
    );
}

A note about the GenericDropdownConfigProvider: If the root renderbox of the dropdown is not the original root (e.g. if the dropdown is inside a Storybook), you need to provide a GlobalKey with the root screen render box reference. Otherwise, the position of the content will be calculated incorrectly.
