fromBase64 static method
Creates a lazy strict canonical padded standard Base64 source.
Decoding occurs during run. URL-safe, unpadded, whitespace-containing, and otherwise noncanonical representations are rejected.
Implementation
static CryptoFlow<Uint8List> fromBase64(String value) => CryptoFlow._(
_FlowSource('source.base64', () => CryptoBytes.decodeBase64(value)),
const [],
);
