Floating Menu Expendable #

A draggable floating handle that opens a customizable panel (side or vertical).

Designed for:

• Quick actions / shortcuts
• Floating toolbars
• Chat / support / menu buttons

Features #

• Draggable and snaps to the nearest screen edge
• Two open modes:
  • FloatingMenuExpendableOpenMode.side: panel opens horizontally next to the handle
    • FloatingMenuExpendableOpenMode.vertical: panel opens below the handle (or above if near bottom)
• Background barrier with blur + color, dismissible on tap
• UI customization via FloatingMenuExpendableStyle
• FloatingMenuExpendableController for open/close/toggle and side tracking

New:

• Expand from the handle (unified handle + panel) using expandPanelFromHandle
• Switch handle content while open using handleOpenChild (defaults to a close icon)

Default behavior:

Expand-from-handle behavior:

Installation #

Add the package to your pubspec.yaml.

Import #

import 'package:floating_menu_expendable/floating_menu_expendable.dart';

Quick usage #

final controller = FloatingMenuExpendableController();

Stack(
	children: [
		FloatingMenuExpendable(
			controller: controller,
			panelWidth: 320,
			panelHeight: 240,
			handleChild: const Icon(Icons.menu),
			panelChild: const ColoredBox(color: Colors.white),
		),
	],
)

Expand from handle (new) #

If you want the panel to expand from the same handle (so it looks like one widget), enable expandPanelFromHandle.

FloatingMenuExpendable(
	controller: controller,
	panelWidth: 320,
	panelHeight: 240,
	expandPanelFromHandle: true,
	// Optional: what to show inside the handle when open.
	handleOpenChild: const Icon(Icons.close_rounded),
	handleChild: const Icon(Icons.menu),
	panelChild: const ColoredBox(color: Colors.white),
)

Customize the UI (Style) #

Use FloatingMenuExpendableStyle to customize blur, barrier color, panel radius, and handle ink effects.

FloatingMenuExpendable(
	controller: controller,
	panelWidth: 320,
	panelHeight: 240,
	handleChild: const Icon(Icons.menu),
	panelChild: const ColoredBox(color: Colors.white),
	style: const FloatingMenuExpendableStyle(
		// Background barrier
		showBarrierWhenOpen: true,
		barrierDismissible: true,
		barrierColor: Color(0x66000000),
		barrierBlurSigmaX: 10,
		barrierBlurSigmaY: 10,

		// Panel
		panelBorderRadius: BorderRadius.all(Radius.circular(18)),
	),
)

Controller #

controller.open();
controller.close();
controller.toggle();

You can also listen to where the handle is docked:

• controller.physicalSide (left / right)
• controller.verticalSide (top / bottom) when using vertical mode

Example app #

See the runnable Flutter demo in the example/ folder.

Notes #

• The widget is intended to be used inside a Stack.
• Provide your own panelChild and handleChild to match your app UI.
