Decodes the data as a collection of key-value pairs. The pairs are decoded in order of appearance in the encoded data.
Implementation
@override
KeyedDecoder decodeKeyed() {
throw CodableException.unsupportedMethod('CsvDecoder', 'decodeKeyed',
reason: 'Row-level decoding only supports decodeKeyed() and decodeMapped().');
}
