My code Implementation as per the given documentation

I tried to use the package to get data from Spotify API. I made a new client as shown below

class SpotifyOAuth2Client extends OAuth2Client {
  SpotifyOAuth2Client(
      {@required String redirectUri, @required String customUriScheme})
      : super(
            authorizeUrl:
                'https://accounts.spotify.com/authorize', 
            tokenUrl:
                'https://accounts.spotify.com/api/token', 
            redirectUri: redirectUri,
            customUriScheme: customUriScheme) {
    this.accessTokenRequestHeaders = {'Accept': 'application/json'};
  }
}

I used this code to get data using the helper

    SpotifyOAuth2Client client = SpotifyOAuth2Client(
        customUriScheme: 'mypakagename',
        redirectUri: 'mypackagename:/oauth2redirect');

    OAuth2Helper helper = OAuth2Helper(client,
        grantType: OAuth2Helper.AUTHORIZATION_CODE, clientId: _keys[0]);

The Problem

This code works perfectly, except this wont store tokens Everytime this code is run, it redirects me to get an accesstoken again. So I tried the code below.

My improvisation

OAuth2Helper auth2helper = OAuth2Helper(client);
    auth2helper.setAuthorizationParams(
        grantType: OAuth2Helper.AUTHORIZATION_CODE,
        clientId: _keys[0],
        clientSecret: _keys[1]);
    auth2helper.getToken();

Error found during the improvisation When I execute this code I get the following error

Unhandled Exception: Exception: "state" parameter in response doesn't correspond to the expected value

Is there something wrong with the package or is my implementationwrong? Do help me out

Hi @hvkalayil, thank you for the detailed report. There was a problem when empty scopes (or no scopes at all) were used. It should be fixed now, can you check the latest release (1.4.3)?

[hvkalayil]

Thanks. Its working now. This package is extremely useful. Thanks for your work

I am experiencing this in version 2.3.2. For android its working perfectly but in iOS it keeps trying to redirect me to get an accesstoken again.

Hi @Mubaola23. I am facing the same issue. Did you found any fix? Note: It is happening only in some android devices.
