spotify_sdk #
Description #
This is a flutter package that wraps the native iOS and Android Spotify "remote" SDKs as well as the Spotify Web Playback SDK for web. Since it wraps the native SDKs it has the same features and limitations.
Installation #
To use this plugin, add spotify_sdk as a dependency in your pubspec.yaml file like this
dependencies:
spotify_sdk:
copied to clipboard
This will get you the latest version.
Setup #
Android #
This package is using both the spotify-app-remote sdk and spotify-auth library. The auth library is needed to get the access token to work with the web api.
From the Spotify Android SDK Quick Start. You need two things:
Register your app in the spotify developer portal. You also need to create a sha-1 fingerprint and add this and your package name to the app settings on the dashboard as well as a redirect url.
download the current Spotify Android SDK. Here you need the spotify-app-remote-*.aar.
After you are all setup you need to add the SDKs *.aar file to your Android Project as Module. See the Spotify Android SDK Quick Start for detailed information.
Installation instructions for Android Studio 4.2+
Since Android Studio 4.2 you need to manually perform these steps in order to add .jar/.aar files:
Open the android folder of your flutter project as an Android Studio project
In the android root folder create a single folder for spotify-app-remote, place the corresponding aar file and create an empty build.gradle file, like on the screenshot below:
Content of the spotify-app-remote/build.gradle file:
configurations.maybeCreate("default")
artifacts.add("default", file('spotify-app-remote-release-x.x.x.aar'))

In the android root folder find settings.gradle file, open it and add the following line at the top of the file:
include ':spotify-app-remote'

iOS #
Register your app in the spotify developer portal. You also need to register your Bundle ID as well as a Redirect URI.
Follow the instructions in the section Setup the iOS SDK of Spotify iOS SDK Quick Start.
Web #
Register your app in the spotify developer portal. You need to provide a redirect URL which points to a dedicated page on a website you own.
Paste the following onto the webpage, which you linked to in your redirect URL.
<!DOCTYPE html>
<html>
<head>
<title>Authenticating Spotify</title>
</head>
<body>
<p>Please wait while we authenticate Spotify...</p>
<script type="text/javascript">
if(window.opener) {
window.opener.postMessage('?' + window.location.href.split('?')[1], "*");
} else {
window.close();
}
</script>
</body>
</html>
copied to clipboard
Optionally add this to your Flutter app web/index.html to avoid a Javascript TypeError: r.__extends is not a function error in development mode.
<script src="https://sdk.scdn.co/spotify-player.js"></script>
<script>
window.onSpotifyWebPlaybackSDKReady = (evt) => {};
</script>

You need Spotify Premium to access the Web SDK.
Usage #
To start using this package first import it in your Dart file.
import 'package:spotify_sdk/spotify_sdk.dart';
copied to clipboard
To connect to the Spotify app you can call connectToSpotifyRemote(...) or getAccessToken(...). In both of these methods you need the client id, which you will find in the Spotify developer dashboard and the redirect url you set there for that specific client.
await SpotifySdk.connectToSpotifyRemote(clientId: "", redirectUrl: "")
copied to clipboard
If you want to use the web api as well you have to use this method to get the access token.
You can specify multiple scopes by separating them with a comma "," as shown below. For more information on scopes you can refer to Spotify Authorization Scopes Guide
var accessToken = await SpotifySdk.getAccessToken(clientId: "", redirectUrl: "", scope: "app-remote-control,user-modify-playback-state,playlist-read-private");
copied to clipboard
On Web you can use the token that you get from getAccessToken(...) and then pass it to connectToSpotifyRemote(...). This will avoid having to send user through two Spotify OAuth prompts. You should not persist this token, nor supply a different token, because the refresh token is only set interally by getAccessToken or connectToSpotifyRemote.
On iOS you can store the token that you get from getAccessToken(...) and then pass it to connectToSpotifyRemote(...) during the next session. This will avoid having to switch to the Spotify app for establishing the connection. This library does not handle storing the token. It is up to you to persist it wherever you see fit. Keep in mind that this feature is currently quite buggy in the native iOS SDK and has many side effects like random disconnections. Proceed with caution.
On iOS Spotify starts playing music when attempting connection. This is a default behavior and there is no official way to prevent this with the currently supported authentication flows. You have the option to pass a Spotify URI upon connection or set it to a blank string to play the last played song. There is an undocumented workaround if you don't want music to start playing which is to pass an invalid Spotify URI instead. This is not officially supported by the Spotify SDK or this library and it can fail or stop working at any time!
Have a look in the example for detailed insights on how you can use this package.
Token Swap #
You can optionally specify "token swap" URLs to manage tokens with a backend service that protects your OAuth client secret. For more information refer to the Spotify Token Swap and Refresh Guide
SpotifySdkPlugin.tokenSwapURL = 'https://example.com/api/spotify/token';
SpotifySdkPlugin.tokenRefreshURL = 'https://example.com/api/spotify/refresh';
copied to clipboard
On web, this package will perform an Authorization Code (without PKCE) flow, then exchange the code and refresh the token with a backend service you run at the URLs provided.
Token Swap is for now "web only". While the iOS SDK also supports the "token swap", this flow is not yet supported.

On Web, an automatic call to play may not work due to media activation policies which send an error: "Authentication Error: Browser prevented autoplay due to lack of interaction". This error is ignored by the SDK so you can still present a button for the user to click to play or resume to start playback. See the Web SDK Troubleshooting guide for more details.
