isNullOrBlank method

bool isNullOrBlank(
  1. dynamic value
)

Checks if data is null or blank (empty or only contains whitespace).

Implementation

static bool isNullOrBlank(dynamic value) {
  if (isNull(value)) {
    return true;
  }

  if (value is String) {
    return value.toString().trim().isEmpty;
  }

  // Pretty sure that isNullOrBlank should't be validating
  // iterables... but I'm going to keep this for compatibility.
  return _hasIsEmpty(value) ? value.isEmpty as bool : false;
}
