hashTypedData function

Uint8List hashTypedData(
  1. String typeTag,
  2. Uint8List data
)

Generates a Sha3256 hash of typed data as a base64 string.

Implementation

Uint8List hashTypedData(String typeTag, Uint8List data) {
  final typeTagBytes = "$typeTag::".codeUnits;

	final dataWithTag = Uint8List(typeTagBytes.length + data.length);
	dataWithTag.setAll(0, typeTagBytes);
	dataWithTag.setAll(typeTagBytes.length, data);

	return keccak256(dataWithTag);
}
