EasyDropdown class

A widget that provides dropdown functionality.

The EasyDropdown widget wraps an existing child widget and adds the ability to display a dropdown list of items when activated. It is typically used to create dropdown menus.

Example usage:

EasyDropdown(
  key: _dropDownKey, // GlobalKey<EasyDropdownState>
  config: const EasyDropdownConfig(
    radius: 16,
  ),
  items: Future.sync(() async {
    await Future.delayed(const Duration(seconds: 2));
    return [
      EasyDropdownTile(title: 'Test', onPressed: () {}),
      EasyDropdownTile(title: 'Test 1', onPressed: () {}),
      EasyDropdownTile(title: 'Test 2', onPressed: () {}),
    ];
  }),
  // items: [
  //    EasyDropdownTile(title: 'Test', onPressed: () {}),
  //    EasyDropdownTile(title: 'Test 1', onPressed: () {}),
  //    EasyDropdownTile(title: 'Test 2', onPressed: () {}),
  //  ],
  child: RaisedButton(
    onPressed: () {
      _dropDownKey.currentState?.showOverlay();
    },
    child: Text(
      'A selected field',
    ),
  ),
);
