Basic Usage

Import it to your project file

import 'package:circular_menu/circular_menu.dart';

And add it in its most basic form like it:

final circularMenu = CircularMenu(items: [
    CircularMenuItem(icon: Icons.home, onTap: () {
      // callback
    }),
    CircularMenuItem(icon: Icons.search, onTap: () {
      //callback
    }),
    CircularMenuItem(icon: Icons.settings, onTap: () {
      //callback
    }),
    CircularMenuItem(icon: Icons.star, onTap: () {
      //callback
    }),
    CircularMenuItem(icon: Icons.pages, onTap: () {
      //callback
    }),
  ]);

There are additional optional parameters to initialize the menu with.

  final circularMenu = CircularMenu(
      // menu alignment
      alignment: Alignment.bottomCenter,
      // menu radius
      radius: 100,
      // widget in the background holds actual page content
      backgroundWidget: MyCustomWidget(),
      // global key to control the animation anywhere in the code.
      key: // GlobalKey<CircularMenuState>(),
      // animation duration
      animationDuration: Duration(milliseconds: 500),
      // animation curve in forward
      curve: Curves.bounceOut,
      // animation curve in reverse
      reverseCurve: Curves.fastOutSlowIn,
	// first item angle
      startingAngleInRadian : 0 ,
	// last item angle
      endingAngleInRadian : pi,
      // toggle button callback
      toggleButtonOnPressed: () {
        //callback
      },
      // toggle button appearance properties
      toggleButtonColor: Colors.pink,
      toggleButtonElevation: 4.0,
      toggleButtonIconColor: Colors.white,
      toggleButtonMargin: 10.0,
      toggleButtonPadding: 10.0,
      toggleButtonSize: 40.0,
      items: [
        CircularMenuItem(
          // menu item callback
          onTap: () {
            // callback
          },
          // menu item appearance properties
          icon: Icons.home,
          color: Colors.blue,
          elevation: 4.0,
          iconColor: Colors.white,
          iconSize: 30.0,
          margin: 10.0,
          padding: 10.0,
          // when 'animatedIcon' is passed,above 'icon' will be ignored
           animatedIcon:// AnimatedIcon(),
        ),
        CircularMenuItem(
            icon: Icons.search,
            onTap: () {
              //callback
            }),
        CircularMenuItem(
            icon: Icons.settings,
            onTap: () {
              //callback
            }),
        CircularMenuItem(
            icon: Icons.star,
            onTap: () {
              //callback
            }),
        CircularMenuItem(
            icon: Icons.pages,
            onTap: () {
              //callback
            }),
      ]);

control animation anywhere in your code using a key:

  GlobalKey<CircularMenuState> key = GlobalKey<CircularMenuState>();
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Colors.pink,
        title: Text(
          'Flutter Circular Menu',

          ),
        ),
      ),
      body: CircularMenu(
        alignment: Alignment.bottomCenter,
        startingAngleInRadian: 1.25 * pi,
        endingAngleInRadian: 1.75 * pi,
        backgroundWidget: Center(
