# `ExGram.FSM.Filter.InFlow`
[🔗](https://github.com/rockneurotiko/ex_gram_fsm/blob/v0.1.0/lib/ex_gram/fsm/filter/in_flow.ex#L1)

An `ExGram.Router.Filter` that matches when any FSM flow is active.

This filter is automatically registered as the `:in_flow` alias when
`use ExGram.FSM` detects that `use ExGram.Router` has also been called on
the same module.

## Usage

Use in a scope to match when any flow is active:

    scope do
      filter :in_flow
      handle &MyBot.Handlers.in_flow/1
    end
