Better typesafety for getRoutes function

[max-programming]

This PR uses the types from the backend libraries and makes the getRoutes function more typesafe

Let me know if any further changes are required

Hi @max-programming! Thank you so much for this PR and apologies for late response here.
You're importing types from all packages that user may not have - would that cause issues for them?

[max-programming]

@VladimirMikulic I don't think that will be a problem. Because the packages are installed here in the route-list library.

Secondly we're only importing types just for better type checking when the users use the library

[VladimirMikulic]

@max-programming they are installed but as dev dependencies?

[max-programming]

I think because we only use the types, we don't really need them in dependencies
As the code is not going to run on the runtime, it's just the types
