valueOfString static method

Long valueOfString(
  1. String str, [
  2. int radix = 10
])

Returns a Long instance from a string.

str the string representation radix the radix to use for parsing (default is 10)

A wrapper class for large integers that provides Java-like functionality.

This class wraps Dart's int type but is designed for large integer values, similar to Java's Long class.

Example usage:

Long a = Long(9223372036854775807);
Long b = Long.valueOf(1000000000000);
Long c = Long.parseLong("123456789012345");

print(a.toString()); // "9223372036854775807"
print(a.compareTo(b)); // 1

Implementation

static Long valueOfString(String str, [int radix = 10]) {
  return parseLong(str, radix);
}
