Base64Decoder class final
Decoder for base64 encoded data.
This decoder accepts both base64 and base64url ("url-safe") encodings.
The encoding is required to be properly padded.
Throws a FormatException if the input is not valid base64 data.
Example:
final base64Decoder = base64.decoder;
const base64Bytes = 'RGFydCBpcyBvcGVuIHNvdXJjZQ==';
final decodedBytes = base64Decoder.convert(base64Bytes);
// decodedBytes: [68, 97, 114, 116, 32, 105, 115, 32, 111, 112, 101, 110,
// 32, 115, 111, 117, 114, 99, 101]
// Print as string using UTF-8 decoder
print(utf8.decode(decodedBytes)); // Dart is open source
