PullDownButton

PullDownButton is a widget used to show the pull-down menu.

While the pull-down menu is opened, the button from where this menu was called will have lower opacity.

PullDownButton(
  itemBuilder: (context) => [
    PullDownMenuItem(
      title: 'Menu item',
      onTap: () {},
    ),
    const PullDownMenuDivider(),
    PullDownMenuItem(
      title: 'Menu item 2',
      onTap: () {},
    ),
  ],
  buttonBuilder: (context, showMenu) => CupertinoButton(
    onPressed: showMenu,
    padding: EdgeInsets.zero,
    child: const Icon(CupertinoIcons.ellipsis_circle),
  ),
);

PullDownMenuItem

PullDownMenuItem is a widget used to create cupertino-style pull-down menu item.

PullDownMenuItem(
  onTap: () {},
  title: 'Pin',
  icon: CupertinoIcons.pin,
),
PullDownMenuItem(
  title: 'Forward',
  subtitle: 'Share in different channel',
  onTap: () {},
  icon: CupertinoIcons.arrowshape_turn_up_right,
),
PullDownMenuItem(
  onTap: () {},
  title: 'Delete',
  isDestructive: true,
  icon: CupertinoIcons.delete,
),

PullDownMenuItem.selectable

PullDownMenuItem.selectable is a widget used to create cupertino-style pull-down menu item with selection state.

PullDownMenuItem.selectable(
  onTap: () {},
  selected: true,
  title: 'Green',
  icon: CupertinoIcons.circle_fill,
  iconColor: CupertinoColors.systemGreen.resolveFrom(context),
),
PullDownMenuItem.selectable(
  onTap: () {},
  selected: false,
  title: 'Orange',
  icon: CupertinoIcons.circle_fill,
  iconColor: CupertinoColors.systemOrange.resolveFrom(context),
),
PullDownMenuItem.selectable(
  onTap: () {},
  selected: false,
  title: 'Indigo',
  icon: CupertinoIcons.circle_fill,
  iconColor: CupertinoColors.systemIndigo.resolveFrom(context),
),

PullDownMenuActionsRow

PullDownMenuActionsRow is a widget used to create cupertino-style pull-down menu row of actions (small or medium size).

PullDownMenuActionsRow.medium(
  items: [
    PullDownMenuItem(
      onTap: () {},
      title: 'Reply',
      icon: CupertinoIcons.arrowshape_turn_up_left,
    ),
    PullDownMenuItem(
      onTap: () {},
      title: 'Copy',
      icon: CupertinoIcons.doc_on_doc,
    ),
    PullDownMenuItem(
      onTap: () {},
      title: 'Edit',
      icon: CupertinoIcons.pencil,
    ),
  ],
),

PullDownMenuItem is used to populate PullDownMenuActionsRow.items. Depending on PullDownMenuActionsRows size, PullDownMenuItem might be either icon only or icon and title in a vertical array.

PullDownMenuDivider

PullDownMenuDivider.large is a widget used to create cupertino-style pull-down menu large divider.

There is no need in adding PullDownMenuDivider by hand, pull-down menu does it automatically!

PullDownMenuTitle

PullDownMenuTitle is a widget used to create cupertino-style pull-down menu title (usually at the top of menu).

const PullDownMenuTitle(title: Text('Menu title')),

PullDownMenuHeader

PullDownMenuHeader is a widget used to create cupertino-style pull-down menu document header (usually at the top of menu).

PullDownMenuHeader(
  leading: ColoredBox(
    color: CupertinoColors.systemBlue.resolveFrom(context),
  ),
  title: 'Profile',
  subtitle: 'Tap to open',
  onTap: () {},
  icon: CupertinoIcons.profile_circled,
),

showPullDownMenu

An alternative way of displaying pull-down menu via a function call.

onPressed: () async {
  /* get tap position and / or do something before opening menu */

  await showPullDownMenu(
    context: context,
    items: [...],
    position: position,
  );
}

PullDownMenu

Another alternative way of displaying the pull-down menu as a simple widget, with no animations or adding routes to the navigation stack.

PullDownMenu(
  items: [
    PullDownMenuItem(
      title: 'Menu item',
      onTap: () {},
    ),
    const PullDownMenuDivider(),
    PullDownMenuItem(
      title: 'Menu item 2',
      onTap: () {},
    ),
  ]
),

Theming

This package also provides additional customization. By default, the iOS 16 theme is used, but it is also possible to override defaults with widget properties (see above) or with PullDownButtonTheme theme extension.

Light Theme	Dark Theme

PullDownButtonTheme

To use PullDownButtonTheme define it in your ThemeData as follows:

ThemeData(
  ...,
  extensions: [
    PullDownButtonTheme(
      routeTheme: PullDownMenuRouteTheme(
        backgroundColor: Colors.grey,
      ),
      itemTheme: PullDownMenuItemTheme(
        destructiveColor: Colors.red,
      ),
      dividerTheme: PullDownMenuDividerTheme(
        dividerColor: Colors.black,
      ),
    ),
  ],
),

PullDownButtonTheme uses a set of sub-themes (for items, dividers, the menu itself, etc.) to define the needed theme. See below for every property each sub-theme provides.

PullDownButtonInheritedTheme

If defining PullDownButtonTheme in ThemeData is not possible, for example, if you are using CupertinoApp, you can use PullDownButtonInheritedTheme:

CupertinoApp(
  builder: (context, child) => PullDownButtonInheritedTheme(
    data: const PullDownButtonTheme(
      ...
    ),
    child: child!,
  ),
  home: ...,
),

Here is an example of using PullDownButtonTheme with Material 3 color scheme colors (generated from CupertinoColors.systemBlue with ColorScheme.fromSeed) from Material 3 Menu specs.
