hey, @ziye201810 thanks for submitting work.

Polyline icons must also support predefined SymbolPaths. Can you add that to google-types?

[puneet24]

Is there any alternative of implementing icons property till icons property is added in agm-polyline

[jimmykane]

Hi any news on this ?

[ghost]

the creator of the PR is not responding to my change request, but this is a high priority thing so I think I'll just fork it and do it myself. Not promising, but should be done by end of week.

[jimmykane]

@doom777 Got it. Yeah sorry I commented too fast. Have been requesting this (and monitoring the closed issues) for quite some time now.

Indeed this is becoming quite high prio as most maps need those kinda arrows and so on.

Thanks for the reply, good luck and you have already my kudos!
