toBase64Bytes function

Uint8List toBase64Bytes(List<int> input, { Base64Codec? codec, bool url = false, bool padding = true, })

Converts 8-bit integer sequence to Base-64 and returns the ASCII bytes.

This is the same as toBase64 but returns the encoded characters as a Uint8List of ASCII codes, skipping the intermediate String.

Parameters:

• input is a sequence of 8-bit integers
• If url is true, URL and Filename-safe alphabet is used.
• If padding is true, the output will have padding characters.
• codec is the Base64Codec to use. It is derived from the other parameters if not provided.

Implementation

Uint8List toBase64Bytes(
  List<int> input, {
  Base64Codec? codec,
  bool url = false,
  bool padding = true,
}) {
  codec ??= _codecFromParameters(
    url: url,
    padding: padding,
  );
  Uint8List out = codec.encoder.convert(input);
  if (!padding && _codecsWithPadding.contains(codec)) {
    out = Uint8List.fromList(
      out.takeWhile((x) => x != codec!.encoder.padding).toList(),
    );
  }
  return out;
}
