## Why

The official Twitch mobile app doesn't support emotes from [7TV](https://chrome.google.com/webstore/detail/7tv/ammjkodgmmoknidbanneddgankgfejfh), [BetterTTV (BTTV)](https://chrome.google.com/webstore/detail/betterttv/ajopnjidmegmdimjlfnijceegpefgped), and [FrankerFaceZ (FFZ)](https://chrome.google.com/webstore/detail/frankerfacez/fadndhdgpmmaapbmfcknlfgcflmmmieb) — third-party extensions for Twitch used by millions. As a result, only emote text names are rendered rather than their actual image or GIF, making the chat unreadable in many channels.

## Features

- Support for 7TV, BetterTTV, and FrankerFaceZ emotes and badges
- Browse followed streams, top streams, and top categories
- Autocomplete for emotes and user mentions
- Light, dark, and black (OLED) themes
- Search for channels and categories
- See and filter chatters in a channel
- Local chat user message history
- Theater and fullscreen mode
- Watch live streams with chat
- Picture-in-picture mode
- Block and report users
- Emote menu
- Sleep timer
- And more...

## Development setup

1. [Install Flutter](https://docs.flutter.dev/get-started/install).

2. Clone this repo (e.g., `git clone https://github.com/tommyxchow/frosty.git`).

3. Go to the [Twitch dev console](https://dev.twitch.tv/login) and register a new application to retrieve a **Client ID** and **Client Secret**.

4. Copy `.env.example` to `.env` and fill in your credentials:

   ```bash
   cp .env.example .env
   ```

5. Run `flutter pub get` to fetch all the dependencies.

6. Choose an emulator or device and run the app! The included VS Code launch configurations will automatically read your `.env` file.

7. (Optional) Run `dart run scripts/get_twitch_token.dart` to quickly get a user auth token. Long-press the **Anonymous** account tile in the app to log in.
