A major problem with the official Twitch app for many users is that emotes from services such as [BetterTTV (BTTV)](https://chrome.google.com/webstore/detail/betterttv/ajopnjidmegmdimjlfnijceegpefgped), [FrankerFaceZ (FFZ)](https://chrome.google.com/webstore/detail/frankerfacez/fadndhdgpmmaapbmfcknlfgcflmmmieb), and [7TV](https://chrome.google.com/webstore/detail/7tv/ammjkodgmmoknidbanneddgankgfejfh) 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).
1. Go to the [Twitch dev console](https://dev.twitch.tv/login) and register a new application to retrieve a **client ID** and **client secret** and add a **OAuth redirect URL**.
2. Clone the repo to a directory.
3. Navigate to `lib/constants/constants.dart` and replace the `clientId` and `secret` constants with your **client ID** and **client secret** (or better yet, if using VSCode use `--dart-define` to [define them as environment variables](https://dartcode.org/docs/using-dart-define-in-flutter/)).
4. Navigate to `android/app/src/main/AndroidManifest.xml` and under the `flutter_web_auth` intent filter replace the value of `android:scheme` to the scheme in your **OAuth redirect URL**.
5. Run `flutter pub get` to fetch all the dependencies.
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.
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.
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.
This seems to be caused by the Flutter framework itself (see [here](https://github.com/flutter/flutter/issues/24804) and [here](https://github.com/flutter/flutter/issues/29130)).
I'm limited to what is available in the [Twitch API](https://dev.twitch.tv/docs/api/reference), 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.
You can open a new issue [here](https://github.com/tommyxchow/frosty/issues) with the appropriate labels (e.g., "bug" or "feature request") and I'll take a look at it.
