addAttribute method

void addAttribute(
  1. String key,
  2. dynamic value
)

Adds a custom attribute with key and value to all future events sent by the RUM monitor. Note that value must be supported by StandardMessageCodec. Passing a value of null is the same as calling removeAttribute

Implementation

void addAttribute(String key, dynamic value) {
  if (value == null) {
    removeAttribute(key);
    return;
  }
  wrap('rum.addAttributes', logger, {'value': value}, () {
    return _platform.addAttribute(key, value);
  });
}
