Returns a Future<String> containing the JSON string of the rendered data.

Implementation

Future<String> renderData({
  required Map<String, Object?> data,
  int status = 200,
}) async {
  try {
    try {
      response.statusCode = status;
      response.headers.contentType = ContentType.json;
    } catch (e) {
      Console.i(e);
    }

    var renderString = WaJson.jsonEncoder(data, rq: this);
    await writeAndClose(renderString);
    return renderString;
  } catch (e) {
    try {
      response.statusCode = 502;
      response.headers.contentType = ContentType.json;
    } catch (e) {
      Console.i(e);
    }

    return jsonEncode({
      'status': 502,
      'error': e,
    });
  }
}
