Debug printing widgets was quite verbose. While developing a widget, you often want to see a full debug printout, but this feature assumes that debug printing a WidgetInstance should show a summary of the widget, not a full debug printout containing cached glyph information of every label. By default, summarize just calls Debug, but this extra layer allows widgets to provide a more condensed summary and exclude details like caches. Originally, adding dbg!() around the theme example's UI yielded a whopping 20,324 lines of text. The summary code only prints 3,858 lines.
