Thanks this is very cool.
However I don't think a widget contributed should use text instead of label as a label unless its clear why - you're causing an app to have a mix of text display when that may not be wanted. Would widget.Label work here?

Hi @andydotxyz I made some tests with widget.Label but this widget inherits a lot of settings from theme (like padding for example). That make the text very hard to place under the led icon. (In alternative I would have to make a very bigger led).

This object i more like a gauge so I think the text under it can be considered more like any other graphical item and in this way the coanvas.text give us more freedom to handle it.

If you want to use the canvas.Text in this way it will need to respect the theme for at least the colour, if not the size information as well.

And you should test that it updates when the theme changes too!
