Manage multiple icons 👨‍👩‍👦‍👦,

and compose them just like a widget 🎶

Features

pub score pub version (including pre-releases) pub publisher

  • Control multiple tray icons
  • Many options for setting the tray icons image
    • .ico file either from the file system or the Flutter assets directory
    • Set the pixels directly through an image buffer - you can use this to dynamically create an image via canvas!
    • Use default system icons like the ❔ or the elevation prompt 🛡️
  • Widget api - treat the tray icon as part of your UI and compose it in your build methods

Usage

After you've added betrayal to your dependencies via flutter pub add betrayal and flutter pub get, you can start to use it:

import 'package:betrayal/betrayal.dart';

// ...

@override
Widget build(BuildContext context) => MaterialApp(
  home: Scaffold(
    appBar: AppBar(
      title: const Text("Look at the system tray 👀")
    ),
    body: Center(
      // The icon will be visible aslong as the [TrayIconWidget] will be built
      child: TrayIconWidget(
        winIcon: WinIcon.application,
        tooltip: "Here I am!"
        child: FlutterLogo()
      )
    )
  )
);

If you just want a tray icon, that's pretty much all you need to know.

There is, however, also a quick-guide README.md, four example applications and of course the API docs, if you do want to learn more.

Don't hesitate to file an issue, I'll have a look at it eventually 😊
