# Using Flutter SDK

Embedded Wallets provides a comprehensive set of functions to handle authentication, user management, and blockchain interactions in your Flutter applications. These functions allow you to implement features like user sign-in, Multi-Factor Authentication (MFA), private key retrieval, and Wallet Services with minimal effort. Each function is designed to handle a specific aspect of Embedded Wallets' functionality, making it easy to integrate into your Flutter projects.

## List of functions

tip

For detailed usage, configuration options, and code examples, refer to the dedicated documentation page for each function.

The code samples use `log` from `dart:developer` and `PlatformException` from `package:flutter/services.dart`. Add these imports to your file:

```dart
