toInteger static method

int? toInteger(
  1. dynamic value
)

Tries to parse value into integer.

null, int, double, bool, String

If none found, then 'null' is returned.

Implementation

static int? toInteger(dynamic value) {
  if (value is int) {
    return value;
  }

  if (value == null) {
    return null;
  }

  if (value is double) {
    return value.toInt();
  }

  if (value is bool) {
    return value ? 1 : 0;
  }

  if (value is String) {
    return int.tryParse(value) ?? double.tryParse(value)?.toInt();
  }

  return null;
}
