-Style text as _italic_, __bold__, or `inline code`.
-- Use bulleted lists
-- To better clarify
-- Your points
-## Links
-You can use [hyperlinks](hyperlink) in markdown
-## Images
-You can include images:
-![Flutter logo](https://flutter.io/images/flutter-mark-square-100.png#100x100)
-## Markdown widget
-This is an example of how to create your own Markdown widget:
-    new Markdown(data: 'Hello _world_!');
