# RtkProvider

A foundational widget that initializes and provides the RealtimeKit environment for a Flutter application. `RtkProvider` acts as a context wrapper that sets up design tokens, client configurations, and UI Kit information required by RealtimeKit components.

## Properties

| Property  | Type                    | Required | Default | Description                                                       |
| --------- | ----------------------- | -------- | ------- | ----------------------------------------------------------------- |
| child     | Widget                  | ✅        | \-      | The widget below this widget in the tree                          |
| meeting   | RealtimekitClient       | ✅        | \-      | Meeting client instance                                           |
| uiKitInfo | RealtimeKitUIInfo       | ✅        | \-      | UI Kit configuration info including design tokens and UI settings |
| observers | List<ProviderObserver>? | ❌        | null    | Riverpod provider observers for debugging                         |

## Usage Examples

### Basic Usage

Dart

```
import 'package:realtimekit_ui/realtimekit_ui.dart';
RtkProvider(  meeting: yourMeetingInstance,  uiKitInfo: yourUiKitInfo,  child: MaterialApp(    home: YourAppHome(),  ),)
```

### With Properties

Dart

```
import 'package:realtimekit_ui/realtimekit_ui.dart';
class MyApp extends StatelessWidget {  @override  Widget build(BuildContext context) {    return RtkProvider(      meeting: RealtimekitClient(        // Client configuration      ),      uiKitInfo: RealtimeKitUIInfo(        // UI Kit information and design tokens      ),      observers: [MyProviderObserver()],      child: MaterialApp(        home: HomeScreen(),      ),    );  }}
```

Note

You do not need to wrap the root of your application inside `RtkProvider`. You can wrap a specific subtree where you use RealtimeKit components. A `MaterialApp` widget must exist below `RtkProvider` in the widget tree.
