Change destination polyline color and driver arrow icon

[Abbasi233]

I examined the GoogleMapsNavigationView class and the GoogleNavigationViewController class, but I could not find a parameter to customize the destination and marker. This kind of feature could be useful for customers who do not want the standard Google navigation theme.
In fact, it would be quite exciting to be able to display the header and footer views as we wish with a builder parameter in GoogleMapsNavigationView :)

Thank you for this feature request, @Abbasi233.

Since this package is only a wrapper for features supported by the Android and iOS SDKs, and those SDKs currently do not support changing route colors or the driver arrow icon, this feature cannot be added to the package at this time.

The idea of adding a builder for a custom footer and header is great, and we can include it in our list of potential future improvements.

Please note that it is already possible to hide the default footer and header and use turn-by-turn events to create custom overlays on the map. You can refer to the turn-by-turn example at: Turn-by-Turn Example.
