Direzione di ricerca

Inizia riproducendo l’errore nello scenario Flutter myapp e segui lo stack trace fino a _deserializeEvent nel client iniettato. Esamina come BuiltJsonSerializers.deserialize gestisce il payload dell’evento e determina perché un _JsonMap viene trattato come una List<Object?>. Il lavoro è completo quando il TypeError segnalato non si verifica più durante la deserializzazione dell’evento.

Scritto dal modello di indicizzazione a partire dal testo della issue.
