Question: How to Guard a Modal?

[Hackmodford]

Is it correct that guards are not run for modal flows?

Edit: I found this in the comments.

  /// Guards on the main router are **not** rerun when starting a flow
  /// (a flow is its own transient state, not a navigation on the main
  /// stack). The sub-router has no guards by default; pass [flowGuards]
  /// if you need them.

Maybe this would be worth pointing out in the docs.

Edit 2: Are guards not run for the first route in a flow? It might also be worth adding the reevaluateOn parameter to running modal flows. Also, having a way to dismiss a modal flow with a guard would be useful.

Edit 3: Now I'm confused why sometimes you can add flowGuards and sometimes it's not an option.
