putString method

BatchEventData putString(
  1. String key,
  2. String value
)

Add a string attribute for the given key.

The attribute key should be a string composed of letters, numbers or underscores ([a-z0-9_]) and can't be longer than 30 characters.

The attribute string value can't be empty or longer than 64 characters. For better results, you should trim/lowercase your strings and use slugs when possible.

Implementation

BatchEventData putString(String key, String value) {
  if (_validateAttributeKey(key)) {
    _attributes[key.toLowerCase()] =
        TypedAttribute(type: TypedAttributeType.string, value: value);
  }
  return this;
}
