--- id: setup sidebar_position: 2 title: Setup --- Understanding Setup For stream_chat_flutter ### Add pub.dev dependency First, you need to add the `stream_chat_flutter` dependency to your `pubspec.yaml`. You can either run this command: ``` flutter pub add stream_chat_flutter ``` OR Add this line in the dependencies section of your pubspec.yaml after substituting latest version: ``` dependencies: stream_chat_flutter_core: ^latest_version ``` ### Details On Platform Support `stream_chat_flutter` was originally created for Android and iOS mobile platforms. As Flutter matured, additional platforms were added and the package now has experimental support for web and desktop as [detailed here](https://getstream.io/blog/announcing-experimental-multi-platform-support-for-the-stream-flutter-sdk/). However, platforms other than mobile may have additional constraints due to not supporting all plugins, which will be addressed by the respective plugin creators over time. ### Setup: iOS The library uses [flutter file picker plugin](https://github.com/miguelpruivo/flutter_file_picker) to pick files from the os. Follow [this wiki](https://github.com/miguelpruivo/flutter_file_picker/wiki/Setup#ios) to fulfill iOS requirements. We also use [video_player](https://pub.dev/packages/video_player) to reproduce videos. Follow [this guide](https://pub.dev/packages/video_player#installation) to fulfill the requirements. To pick images from the camera, we use the [image_picker](https://pub.dev/packages/image_picker) plugin. Follow [these instructions](https://pub.dev/packages/image_picker#ios) to check the requirements. ### Setup: Web Due to Moor web (for offline storage) you need to include the sql.js library: ``` ``` You can grab the latest version of sql-wasm.js and sql-wasm.wasm [here](https://github.com/sql-js/sql.js/releases) and copy them into your `/web` folder.
