+# betrayal
+
+A tray icon plugin for Windows.
+
+## Getting Started
+
+This project is a starting point for a Flutter
+[plug-in package](https://flutter.dev/developing-packages/),
+a specialized package that includes platform-specific implementation code for
+Android and/or iOS.
+
+For help getting started with Flutter, view our
+[online documentation](https://flutter.dev/docs), which offers tutorials,
+samples, guidance on mobile development, and a full API reference.
+
+## TBD
+- FIXME Find out all possible errors and repackage / handle them
+- TODO Write documentation
+- TODO Support Windows default icons ([MAKEINTRESOURCE....](https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-loadicona))
+- TODO Support images
+  - TODO Find out, communicate and memoize the correct system metrics (icon resolution)
+- TODO Support interaction
+  - TODO Support menus
+- TODO Add function to configure a TrayIcon in one call (maybe via a dynamic map actually)
+  - FIXME Use OnWidgetUpdated or smth like that to diff changes between widget dependencies and flush them to the plugin
+- TODO Add second example using the Widget API
+- TODO Support setting titlebar / application icon
+
+Use [https://www.conventionalcommits.org/en/v1.0.0/](https://www.conventionalcommits.org/en/v1.0.0/) for commits.
