Getting Started

Installation

• Method 1 (Recommended):

  run this command in your terminal:

  flutter pub add flutter_context_menu

• Method 2:

  add this line to your pubspec.yaml dependencies:

  dependencies:
      flutter_context_menu: ^0.2.0

  then, run this command in your terminal:

  flutter pub get

Usage

1. First, import the package:

   import 'package:flutter_context_menu/flutter_context_menu.dart';

2. Then, initialize a ContextMenu instance:

   // define your context menu entries
   final entries = <ContextMenuEntry>[
     const MenuHeader(text: "Context Menu"),
     MenuItem(
       label: 'Copy',
       icon: Icons.copy,
       onSelected: () {
         // implement copy
       },
     ),
     MenuItem(
       label: 'Paste',
       icon: Icons.paste,
       onSelected: () {
         // implement paste
       },
     ),
     const MenuDivider(),
     MenuItem.submenu(
       label: 'Edit',
       icon: Icons.edit,
       items: [
         MenuItem(
           label: 'Undo',
           value: "Undo",
           icon: Icons.undo,
           onSelected: () {
             // implement undo
           },
         ),
         MenuItem(
           label: 'Redo',
           value: 'Redo',
           icon: Icons.redo,
           onSelected: () {
             // implement redo
           },
         ),
       ],
     ),
   ];
   
   // initialize a context menu
   final menu = ContextMenu(
     entries: entries,
     position: const Offset(300, 300),
     padding: const EdgeInsets.all(8.0),
   );

3. Finally, to show the context menu, there are two ways:

   • Method 1: Directly calling one of the show methods.

     This will show the context menu at the manually specified position.

     showContextMenu(context, contextMenu: menu);
     // or 
     final selectedValue = await menu.show(context);
     print(selectedValue);

   • Method 2: Using the ContextMenuRegion widget to show the context menu when the user right-clicks or long-presses the region area.

     This will show the context menu where the user clicks when the position property is not specified in the ContextMenu constructor.

     ...
     
     @override
     Widget build(BuildContext context) {
       return Column(
         children: [
           ContextMenuRegion(
             contextMenu: contextMenu,
             onItemSelected: (value) {
               print(value);
             },
             child: Container(
               color: Colors.indigo,
               height: 300,
               width: 300,
               child: const Center(
                 child: Text(
                   'Right click or long press!',
                 ),
               ),
             ),
           )
         ],
       );
     }

Customization

Theme: By default, the context menu and its items uses the MaterialApp's theme data for styling. However, you can customize the appearance and behavior of the context menu by modifying the theme data. Or individually by specifying a BoxDecoration in the boxDecoration property of the ContextMenu.

Custom Entries: You can create your own context menu entries by subclassing the ContextMenuEntry class. This allows you to customize the appearance, behavior, and functionality of the context menu items.
