As I'm learning more about Windows, I think this should be:

'<(PRODUCT_DIR)/<(EXECUTABLE_PREFIX)dart<(EXECUTABLE_SUFFIX)',

+            '<!@(["python", "scripts/list_files.py"])',
+          ],
+          'outputs': [
+            '<(PRODUCT_DIR)/api_docs',

I think this output is a directory. That is still a problem for the same reasons
I mentioned in my previous comments.

+            '<(PRODUCT_DIR)/dart',

See comment above.

+            'apidoc.dart',
+            '--out=<(PRODUCT_DIR)/api_docs',
+            '--mode=live-nav'
+          ],
+        },
+      ],
+    }
+  ],
