Descrizione

Description

During the development process, when adding or deleting hooks, the devServer was not compatible with the destructive modifications to the hook chain. Instead, it directly caused React Native to report an error, making the application unable to run anymore and requiring a restart.

Android Platform

React has detected a change in the order of Hooks called by App. This will lead to bugs and errors if not fixed. For more information, read the Rules of Hooks: https://react.dev/link/rules-of-hooks

  3. Fai un fork del repository e lavora su un branch.
  4. Apri una pull request che faccia riferimento al numero della issue.

Direzione di ricerca

Inizia con il reproducer obbligatorio e la riga 18 di App.tsx, quindi riproduci il problema su Android con React Native 0.82.1 commentando e decommentando ripetutamente l’hook. Analizza il comportamento di Fast Refresh e devServer in relazione alla catena di hook modificata. Il lavoro è completato quando il salvataggio di queste modifiche non lascia più l’app impossibilitata ad avviarsi e non richiede un riavvio.

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