SongInfo is not comparable #5

Closed dvorapa closed 4 years ago

dvorapa commented 4 years ago

Try:

Stream<List<SongInfo>> _songStream =
    Stream.fromFuture(audioQuery.getSongs());
_songStream.listen((List<SongInfo> _songList) {
  _songList.sort();
});

Error thrown in my code:

Recommended patch:

class SongInfo implements Comparable<SongInfo> {

or maybe:

class DataModel implements Comparable<DataModel> {

instead of:

class SongInfo {

A possible workaround until a solution would be:

_songList.sort((a, b) => a.filePath.compareTo(b.filePath));

Closed as solved or closed as wontfix?
