int_range.dart

// https://dartpad.dev/?id=dad879af094b27b24fd6070e1175e791

// Pending feature request: https://github.com/dart-lang/sdk/issues/41717
// Note: this requires Dart 2.14 and above (to support the >>> operator)

class IntRange {
  // based on: https://stackoverflow.com/a/75928881
  static const int maxValue = (-1 >>> 1);
  static const int minValue = -1 - maxValue;
}

void main() {
  print('int: ${IntRange.minValue} to ${IntRange.maxValue}');
}

// in DartPad (32-bit), this will print "int: -2147483648 to 2147483647"
// on Android (64-bit), this will print "int: -9223372036854775808 to 9223372036854775807"
