Alternative routes with on press event

Hello,

How can we show all the routes possible with each one of these a color, and we have on press event to select the route we want? I think we can pass the alternatives=true but the on press how?

The issue mentions the alternatives=true option and asks about selecting a route with an on-press event, but names no files, tests, or entry points. Start by reviewing the component's route-rendering and event API, then define the expected behavior for coloring alternatives and selecting one before implementation. Done should include documented, working alternative-route selection behavior.
