putRawEntry method
Copies an encoded value verbatim, for forward-compatibility round trips.
start must point at the first byte of the value (just past the key) and
end just past it. Wire-type-specific framing is preserved as-is.
Implementation
void putRawEntry(
int fieldId,
int wireType,
Uint8List source,
int start,
int end,
) {
_ensureOpen();
_sink.putRawEntry(fieldId, wireType, source, start, end);
}
