A major problem with the official Twitch app for many users is that emotes from services such as BetterTTV (BTTV), FrankerFaceZ (FFZ), and 7TV are not officially supported. Twitch is unaffiliated with these services, hence why they haven’t been integrated officially.
As a result, the millions of users of these services have an unideal viewing experience on the official Twitch app. In the stream chat, only text is positioned where emotes should be (imagine only being able to see :emoji_code: rather than the emojis themselves).
Frosty aims to bring these emotes and other general quality of life features to both iOS and Android.
Go to the Twitch dev console and register a new application to retrieve a client ID and client secret and add a OAuth redirect URL.
Clone the repo to a directory.
lib/constants/constants.dartand replace the
secretconstants with your client ID and client secret (or better yet, if using VSCode use
--dart-defineto define them as environment variables).
android/app/src/main/AndroidManifest.xmland under the
flutter_web_authintent filter replace the value of
android:schemeto the scheme in your OAuth redirect URL.
flutter pub getto fetch all the dependencies.
Choose an emulator or device and run the app!
Can I change the quality of the stream?
On Android, you can change the stream quality by turning off the custom stream overlay in the settings and tapping the gear icon on the bottom right.
On iOS, sadly quality options aren’t available through the native player and rely on an “auto” setting. There is no official API for getting the live stream URLs so specific quality options are not possible at this time.
Why is there no picture-in-picture (PiP) on Android?
I’ve looked into implementing it for Android a while back but web browsers on Android don’t support the web Picture-in-Picture API. The reason I’m using the web PiP API is due to limitations in the Twitch API (the stream is just the Twitch channel website in fullscreen rather than an actual video player). I might be able to figure something out by working with the native Android code but I’ll have to learn that first.
Why do certain animations and scrolling appear to be janky?
Due to the Flutter framework, there may be some stutter and jank on the first installation and launch. After using and moving around the app for a bit the jank will be mitigated through shader warmup/caching and should be minimal on subsequent launches. Watching a stream with a relatively fast chat for a couple of minutes usually resolves it.
Why isn’t the video stream playing on Android?
If you’re on an older version of Android (below 7.1.1), the video stream will not play properly due to the reliance on Twitch’s web player. Older Android versions use an older version of the native web browser (WebView), resulting in many compatibility issues with newer websites.
Why am I getting ads even though I’m subscribed to the channel or have Turbo?
Even if you’ve logged in to the app, you’ll still have to log in to the WebView so that you can be identified when the stream plays. You can do so by going to the settings and then under the “Account” section tap the “Log in to WebView” button.
Why is there a delay between the stream and chat?
On Android, the delay should be minimal. Try refreshing the player if you have a delay.
On iOS, there seems to be delays up to 15 seconds due to the native player so unfortunately it’s out of my control. The best you can do for now is refreshing or pausing/playing the stream until the delay is minimized.
UPDATE: Starting with version 1.4.0, there is a new message delay option that lets you set the delay (in seconds) before each message is rendered.
Why are some GIFs either slow or very fast?
Why is ProMotion (120hz) not working?
This is caused by the Flutter framework and is being worked on (see here).
UPDATE: With Flutter 3 and version 1.3.0 of the app, ProMotion should be working.
Why is feature “X” from Twitch not in the app as well?
I’m limited to what is available in the Twitch API, so certain features from the Twitch web or mobile app (e.g., voting on predictions and category viewer count) are sadly not available at the moment.
Other features related to ad-blocking or utilizing private APIs will likely not be implemented officially because they would violate Twitch’s terms of service. My highest priority currently is staying on the app stores and focusing on making features for those builds.
I’ll try to add as many features as possible but occasionally I may take a break or be limited in time due to studies and personal reasons.
Where can I report a bug or request a new feature?
You can open a new issue here with the appropriate labels (e.g., “bug” or “feature request”) and I’ll take a look at it.
