ValueUpdate constructor

ValueUpdate(Object? value, { String? ts, Map? meta, String? status, int count = 1, num sum = double.nan, num min = double.nan, num max = double.nan, })

Implementation

  this.sum = double.nan,
  this.min = double.nan,
  this.max = double.nan,
}) {
  ts ??= getTs();

  created = DateTime.now();

  if (meta != null) {
    if (meta['count'] is int) {
      count = meta['count'];
    } else if (value == null) {
      count = 0;
    }

    if (meta['status'] is String) {
      status = meta['status'];
    }

    if (meta['sum'] is num) {
      sum = meta['sum'];
    }

    if (meta['max'] is num) {
      max = meta['max'];
    }

    if (meta['min'] is num) {
      min = meta['min'];
    }
  }

  if (value is num && count == 1) {
    if (sum != sum) sum = value as num;
    if (max != max) max = value as num;

  }
