Search not working

[mjuszczyk1]

I have spotify_io imported like

import 'package:spotify/spotify_io.dart';

Copied the search from the examples directory on this repo

var credentials =
    new SpotifyApiCredentials(spotifyClientId, spotifyClientSecret);
var spotify = new SpotifyApi(credentials);
var search = await spotify.search
    .get("metallica")
    .first(2)
    .catchError((err) => print((err as SpotifyException).message));

And I get a couple errors, the first one seems like a pretty simple fix:

1. [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: type '_TypeError' is not a subtype of type 'SpotifyException' in type cast - this error can be fixed by removing the as SpotifyException cast. I first solved the issue by simply removing the catchError method, which revealed the second bug.

[ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: type 'String' is not a subtype of type 'Map<String, dynamic>'
E/flutter ( 5063): #0      SpotifyApi.handleErrors      package:spotify/src/spotify_io.dart:37
E/flutter ( 5063): #1      SpotifyApi._postImpl         package:spotify/src/spotify_io.dart:21

I dug into this one a bit, but I'm pretty new to Dart/Flutter in general so I couldn't figure out a fix. I believe I traced it, at least, to a line in endpoint_paging.dart - specifically line 163. It seems the _get method is where this bug is actually being generated - I can get a breakpoint to hit on var jsonString = await _api._get(path);, but if I remove it and add one to the next line (var map = json.decode(jsonString);), it never gets hit. I also can't get breakpoints to work in that _get method, so I think this is pretty close to where the bug is coming from, but I'm currently stuck scratching my head.

Figured this out a while ago, forgot to update this.

This can probably be closed, as it's not necessarily a problem with search, per se - the problem was, due to some lazy copy/pasting, I was using spotifyClientId for spotifyClientSecret so I was getting a 401 error.
The part that could be improved is actually throwing that as an error because it does not appear in a debug console (personally just using VisualStudio Code for running/debugging).

I'll release a new package tomorrow, when I'm back on a real computer :)

@mjuszczyk1 does the #29 PR solve this issue? @rinukkusu Can this be closed?
