Implementation

@override
Future<String> readAll() async {
  var finalString = '';
  await for (final chunk in this) {
    try {
      finalString += utf8.decode(chunk.content.toList());
    } catch (e) {
      throw DataStreamError(
        message: 'Failed to decode chunk data: $e',
        reason: DataStreamErrorReason.DecodeFailed,
      );
    }
