lastfm

Description:

lastfm

Last.fm wrapper for Dart #
A package that aims to simplify accessing the Last.fm API from Dart, which can let your users look up song information, track their listening, and like songs, among other things.
Installation #
Add lastfm: ^0.0.1 to the dependencies in your pubspec.yaml or just run one of these:
flutter pub add lastfm
dart pub add lastfm

Usage #

Make sure you have created a Last.fm API account. Get the API key and shared secret into your code safely. DO NOT embed them into your code directly! Instead, write them down somewhere (such as a .gitignored .env file) and build them using --define or (if you're using Flutter) --dart-define.
Authorize your users:

LastFM lastfm = LastFMUnauthorized(apiKey, sharedSecret);
// you can stop here if all you need is to read public data
launch(await lastfm.authorizeDesktop()); //authorizeDesktop returns a URL
sleep(60*1000); //wait for user input here
lastfm = await lastfm.finishAuthorizeDesktop();

Call some methods:

// These all return [XmlDocument]s from the xml package.
// They are wrapped by default, and [LastFMError]s are thrown instead of passed.
final allAboutTool = await lastfm.read('artist.getInfo', {"artist": "Tool"}, false);
final toolsAlbums = await lastfm.read('artist.getTopAlbums', {"artist": "Tool"});
await lastfm.read('track.love', {"track": "Never Gonna Give You Up", "artist": "Rick Astley"});

Keep in mind:

The API key and secret are stored in memory and you don't have to regurgitate them for every request (see above).
The signature shenanigans are taken care of for authenticated read and write methods. If you're using read and you don't want it to be authenticated when it probably is, add a false parameter to the end of the read call (see allAboutTool above).
