bitstring_as_the_bytes function

Uint8List bitstring_as_the_bytes(String bitstring)

[bitstring].length must be a multiple of 8.

Implementation

    if (bitstring.length % 8 != 0) {
        throw Exception('bitstring.length must be a multiple of 8 in this funcion');
    }
    List<int> bytes = [];
    for (int i=0;i<bitstring.length/8;i++) {
        bytes.add(int.parse(bitstring.substring(i*8,i*8+8), radix:2));
    }
    return Uint8List.fromList(bytes);
