Table of Contents #

Usage #

Wrap the widget that should respond to gestures with the PieMenu widget, and provide the menu with an array of PieActions to display as circular buttons.

PieMenu(
  onPressed: () => print('pressed'),
  actions: [
    PieAction(
      tooltip: const Text('like'),
      onSelect: () => print('liked'),
      child: const Icon(Icons.favorite), // Can be any widget
    ),
  ],
  child: ChildWidget(),
),

💡 Don't forget that you can only use PieMenu as a descendant of a PieCanvas widget.

Wrap your page, or any other desired widget for drawing the menu and the background overlay, with PieCanvas widget.

For instance, if you want the menu to be displayed at the forefront, you can wrap your Scaffold with a PieCanvas like following:

PieCanvas(
  child: Scaffold(
    body: YourScaffoldBody(
      ...
        PieMenu(),
      ...
    ),
  ),
),

💡 You can utilize the onPressed callback defined in PieMenu to manage tap events without the need for an extra widget such as GestureDetector.

Customization #

You can customize the appearance and behavior of menus using PieTheme.

Using the theme attribute of PieCanvas widget, you can specify a theme for all the descendant PieMenu widgets.

PieCanvas(
  theme: PieTheme(),
  ...
    PieMenu(), // Uses the canvas theme
  ...
    PieMenu(), // Uses the canvas theme
  ...
),

But if you want to specify menu specific themes, you can also use the theme attribute of PieMenu widget.

PieMenu(
  theme: PieTheme(), // Overrides the canvas theme
),

It is also possible to copy the canvas theme with additional parameters, but make sure you are accessing it with the right context.

PieMenu(
  theme: PieTheme.of(context).copyWith(
    ...
  ),
),

Button themes #

Buttons' background and icon colors are defined by theme's buttonTheme and buttonThemeHovered. You can create a custom PieButtonTheme instances for your canvas and menu themes.

PieTheme(
  buttonTheme: PieButtonTheme(),
  buttonThemeHovered: PieButtonTheme(),
),

You can even give the buttons custom styles using decoration property of PieButtonTheme.

PieButtonTheme(
  decoration: BoxDecoration(),
),

Custom button widgets #

If you wish to use custom widgets inside buttons instead of just icons, it is recommended to use PieAction.builder() with a builder which provides whether the action is hovered or not as a parameter.

PieAction.builder(
  tooltip: const Text('like'),
  onSelect: () => print('liked'),
  builder: (hovered) {
    return Text(
      '<3',
      style: TextStyle(
        color: hovered ? Colors.green : Colors.red,
      ),
    );
  },
),

Tap, long press or right click to activate the menu #

You may set delayDuration of your theme to Duration.zero to activate the menu as soon as the child is pressed.

PieTheme(
  delayDuration: Duration.zero,
),

Using rightClickShowsMenu and leftClickShowsMenu attributes of PieTheme, you can customize the mouse button behavior.

PieTheme(
  rightClickShowsMenu: true,
  leftClickShowsMenu: false,
),

Adjust display angle of menu buttons #

If you don't want the dynamic angle calculation and have the menu appear at a fixed angle, you can set customAngle and customAngleAnchor attributes of PieTheme.

PieTheme(
  customAngle: 90, // In degrees
  customAngleAnchor: PieAnchor.center, // start, center, end
),

You can also use customAngleDiff or spacing to adjust the angle between buttons, and angleOffset to rotate the menu.
