An extensible NMEA0183 parser.

Take a look at the [example](example/example.dart) to see how to use it.

## Usage

```dart

// 1. declare your sentences (use TalkerSentence and ProprietarySentence)

class AbcSentence extends TalkerSentence {

  AbcSentence({required super.raw});

  

  String get data => fields[1];

  

  @override

  bool get valid => super.valid && fields.length == 2;

}

// 2. register your sentences

final decoder = NmeaDecoder()

  ..registerTalkerSentence('ABC', (line) => AbcSentence(raw: line));

// 3. decode a line

final sentence = decoder.decode(r'$--ABC,123456789*5D');

// 4. consume your sentences

print(sentence.valid); // true

print(sentence.checksum); // 5D

print(sentence.source); // --

if (sentence is AbcSentence) {

  print(sentence.data); // 123456789

}

```

You can also use it as a StreamTransformer for a stream of Strings:

```dart

final stream = Stream.fromIterable([r'$--ABC,123456789*5D', r'$--DEF,987654321*5D']);

final transformed = stream.transform(decoder);

transformed.listen((sentence) {

  print(sentence.valid); // true

  print(sentence.checksum); // 5D

  print(sentence.source); // --

  if (sentence is AbcSentence) {

    print(sentence.data); // 123456789

  }

});

```
