StarMenu

Contextual popup menu with different shapes and multiple ways to fine-tune animation and position. The menu entries can be almost any kind of widgets.

Every widgets can now popup a menu on tap! There are currently 3 shapes to choose:

• linear: items are lined by a given angle with a given space between them and with a 3-way alignment.
• circle: items are lined up in a circle shape with a given radius and a star-end angle.
• grid: items are aligned in a grid shape with N columns and a given horizontal and vertical shape.

Using the package is pretty simple:

• make your widget a child of StarMenu:

StarMenu(
  params: StarMenuParameters(),
    onItemTapped: (index, controller) {
      if (index == 7)
        controller.closeMenu();
    }
  ),
  items: entries,
  child: FloatingActionButton(
    onPressed: () {print('FloatingActionButton tapped');},
    child: Icon(Icons.looks_one),
  ),
)

• add the provided addStarMenu() Widget extension to your widget:

FloatingActionButton(
  onPressed: () {print('FloatingActionButton tapped');},
  child: Icon(Icons.looks_one),
).addStarMenu(context, entries, StarMenuParameters()),

where entries is a List<Widget> for the menu entries and StarMenuParameters() is defined as follow:
