parse static method

int parse(dynamic v)

Parses a dynamic value v into an integer.

Tries to convert the dynamic value v into an integer. It supports parsing from int, BigInt, List<int>, and String types. If v is a String and represents a hexadecimal number (prefixed with '0x' or not), it is parsed accordingly.

Parameters:

• v: The dynamic value to be parsed into an integer.

Returns:

• An integer representation of the parsed value.

Implementation

static int parse(dynamic v) {
  try {
    if (v is int) return v;
    if (v is BigInt) return v.toInt();
    if (v is List<int>) {
      return fromBytes(v, sign: true);
    }
    if (v is String) {
      int? parse = int.tryParse(v);
      if (parse == null && StringUtils.ixHexaDecimalNumber(v)) {
        parse = int.parse(StringUtils.strip0x(v), radix: 16);
      }
      return parse!;
    }
  } catch (_) {}
  throw const ArgumentException("invalid input for parse int");
