Response.internalServerError constructor

Response.internalServerError({ Object? body, Map<String, Object>? headers, Encoding? encoding, Map<String, Object>? context, })

Constructs a 500 Internal Server Error response.

This indicates that the server had an internal error that prevented it from fulfilling the request.

body is the response body. It may be either a String, a List<int>, a Stream<List<int>>, or null to indicate no body.

If the body is a String, encoding is used to encode it to a Stream<List<int>>. It defaults to UTF-8. If it's a String, a List<int>, or null, the Content-Length header is set automatically unless a Transfer-Encoding header is set. Otherwise, it's a Stream<List<int>> and no Transfer-Encoding header is set, the adapter will set the Transfer-Encoding header to "chunked" and apply the chunked encoding to the body.

If encoding is passed, the "encoding" field of the Content-Type header in headers will be set appropriately. If there is no existing Content-Type header, it will be set to "application/octet-stream". headers must contain values that are either String or List<String>. An empty list will cause the header to be omitted.

Implementation

Response.internalServerError({
  Object? body,
  Map<String, /* String | List<String> */ Object>? headers,
  Encoding? encoding,
  Map<String, Object>? context,
}) : this(
        500,
        headers: body == null ? _adjustErrorHeaders(headers) : headers,
        body: body ?? 'Internal Server Error',
        context: context,
        encoding: encoding,
      );
