Webargs es una herramienta que fue creada para proporcionar esa funcionalidad sobre varios frameworks, incluido Flask.

Usa Marshmallow por debajo para hacer la validación de datos. Y fue creada por los mismos desarrolladores.

Es una gran herramienta y la he usado mucho también, antes de tener **FastAPI**.

The build session state is managed by the `BuildSessionState` class.
An instance is created at the start of a Gradle invocation and discarded at the end of that invocation.

The build session state also includes "cross session" state that is shared with any "nested" sessions that need to be created.
