描述
Describe the bug
Calling the clear method on map.polylines throws "Unhandled Exception: Unsupported operation: Cannot change an unmodifiable set"
To Reproduce
Steps to reproduce the behavior:
- Just add a clear() call somewhere, though may need to add a few polylines if you don't have them in the sample.
Expected behavior
the set should be mutable and the clear should remove all displayed polylines.
Screenshots
