**You can customize the UI with the type of** QuestThemeConfig **would be**

```dart

          themeConfig: QuestThemeConfig(
              secondaryColor: Colors.red,
              primaryColor: Colors.blue,
              buttonColor: Colors.yellow,
              backgroundColor: Colors.yellow,
              fontStyle: "libre baskerville",
              borderColor: Colors.red
          )
```

### **Basic Usage:**

* In your `main()` function, ensure you initialize the app and dependencies as follows:

```dart
void main() {
  runApp(const MyApp());
  getItInit();
  getIt<SharedPref>().init();
}
```

* Add the following `BlocProvider` setup to your `providers` list to initialize the `ShareWithComponentCubit` for state management:

```dart
providers: [
  BlocProvider(
            create: (context) => getIt<ShareWithComponentCubit>(),
          ),
],
```

Ensure you provide your entity ID, API key, token, user ID, and quest ID

```dart
import 'package:flutter/material.dart';
import 'package:flutter_bloc/flutter_bloc.dart';
import 'package:questlabs_flutter_sdk/questlabs_flutter_sdk.dart';

void main() {

  getItInit();
  getIt<SharedPref>().init();
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});
  @override
  Widget build(BuildContext context) {
    return MultiBlocProvider(
      providers: [
        BlocProvider(
          create: (context) => getIt<ShareWithComponentCubit>(),
        ),
      ],
      child: MaterialApp(
        title: 'Flutter Demo',
        home: CrossSellingComponent(
          questProvider: QuestProvider(
              apiKey: "apiKey",
              entityId: "entityId",
              themeConfig: QuestThemeConfig(
                  // secondaryColor: Colors.red,

              )
          ),
          crossSellingUiPropsModel: CrossSellingUiPropsModel(

            // isEmail: false,
          ),
        )
