Extra widgets you want to fade. Make the map's key the name of the widget and set an array of properties with namedefining the properties you want to keep highlighted. In case of a property which is a function like StreamBuilder's builder set the "type":"function" or in case of a property that has multiple values like Column's children set the "wrapper": "[]". See the full list for more examples.
Updates
v0.2.0
Switched to a list of properties, to support builder and delegated widgets.
v0.1.0
Had a major rewrite to support optionaly empty (no children) widgets. Both Container(width: 250, child: ... ) and Container(height: 250) are valid widgets.
Added fade for the whole widget, not just until the property.
Ex. Container(width: 250, child: ..., padding: ... ) now both width and padding are dimmed.
Bundle size reduced from 22MB to 980KB.
