Struggling with rendering dynamic routes with current folder structure in Nextjs

[abish396]

Below is the image of my folder structure.

I want to know, how to name the dynamic routes and where to place that file so that I can render component with the path https://localhost:3000/treks/[id] like this.
I am facing this issue only with the way shadcn structure the nextjs project. If I use a raw nextjs project then it has a different folder structure.
