How to write a binary literal in Dart

Question

How do you write a Binary Literal in Dart?

I can write a Hex Literal like so:

Int Number = 0xc

If I try the conventional way to write a Binary Literal:

Int Number = 0b1100

I get an error. I've tried to look it up, but I've not been able to find any information other than for hex.

It's not supported in dart. See this Github issue – Colombes

Answer 1

There are currently no built-in binary number literals in Dart (or any base other than 10 and 16).

The closest you can get is: var number = int.parse("1100", radix: 2);.

Maybe you can use this:

// 0b1100 -> 1 at 3th bit and 1 at 2nd bit
final number = 1 << 3 | 1 << 2;

// Print binary string
print(number.toRadixString(2)) // 1100

Try binary package:

import 'package:binary/binary.dart';

void main() {
  // New API.S
  print(0x0C.toBinaryPadded(8)); // 00001100
}

Simple workaround using extensions

void main() {
  print(1110111.b); //prints 119
}

extension Binary on int {
  int get b {
    return int.parse(toRadixString(10), radix: 2);
  }
}
