{"answer":"In Expo/React Native runtimes that do not provide `TextDecoderStream`, install `@stardazed/streams-text-encoding` (and the AI SDK guide's `@ungap/structured-clone` companion polyfill), register `TextEncoderStream` and `TextDecoderStream` as globals before using the AI SDK streaming path, and use `expo/fetch` for chat-response streaming where applicable.","applicability":{"state":"partial","text":"Expo/React Native configurations where AI SDK streaming fails because `TextDecoderStream` is absent or not constructible.
