In Flutter, how can I print out the current widget tree in a widget unit test, in order to understand the current state of the UI for debugging?
(For example, in React/Ensyme, I could use debug(). Is there something comparable in Flutter?)

You can use debugDumpApp
This will print the widget tree based on the Diagnosticable interface, which both Widget, RenderObject and Element implements.
Note that for custom made widgets, you'll have to implement a method for their content to display in that tree: debugFillProperties
