I am using Flutter (Channel dev, v0.3.5, on Mac OS X 10.13.5 17F45c, locale en-IN)
I am getting an assertion failed on the following file.

'package:flutter/src/material/chip_theme.dart': Failed assertion: line 218 pos 12: 'labelStyle != null': is not true.

When the exception was thrown, this was the stack:
