# debug

This block is part of the [`state ui`](https://docs.rual.nl/block-types/state%20ui) group and was last modified in core [`v13.0.4`](https://docs.rual.nl/core-versions/130004).

Shows a debug modal to easily debug values within any flow

- flow `flow`

A typical wiring for [debug](https://docs.rual.nl/block-types/state%20ui/state_debug): a [function trigger](https://docs.rual.nl/block-types/globals/trigger_custom_function) starts the flow; the `flow` out pin feeds [debug](https://docs.rual.nl/block-types/state%20ui/state_debug).
