   we should probably add two things: a matcher that checks if a widget has a descendant, identified by finder:

      expect(find.byType(Foo), hasDescendantWidget(find.text('hello'));

   ...and a finder that takes two finders:

      find.descendant(of: find.byType(Foo), matching: find.text('hello'))

   Thanks! Github is also smart enough to auto-close issues when PRs land if we use the right wording in the PR:
