FusedTransformer class
A Transformer that has a fast path for decoding UTF8-encoded JSON. If the response is utf8-encoded JSON and no custom decoder is specified in the RequestOptions, this transformer is significantly faster than the default SyncTransformer and the BackgroundTransformer. This improvement is achieved by using a fused Utf8Decoder and JsonDecoder to decode the response, which is faster than decoding the utf8-encoded JSON in two separate steps, since Dart uses a special fast decoder for this case. See https://github.com/dart-lang/sdk/blob/5b2ea0c7a227d91c691d2ff8cbbeb5f7f86afdb9/sdk/lib/_internal/vm/lib/convert_patch.dart#L40
By default, this transformer will transform responses in the main isolate, but a custom threshold can be set to switch to an isolate for large responses by passing contentLengthIsolateThreshold.

it is passed to
ResponseInterceptor.override
