# Logto Flutter SDK
[](https://github.com/logto-io/dart/actions/workflows/main.yml)
This project is the official Flutter SDK for [Logto](https://logto.io). It provides a simple way to integrate Logto into your Flutter project.
In the background, this SDK uses the [flutter_web_auth_2](https://pub.dev/packages/flutter_web_auth_2) package to handle the OAuth2 flow.
## Installation
Add the following dependencies to your `pubspec.yaml` file:
```yaml
dependencies:
logto_dart_sdk: ^3.0.0
```
Then run `flutter pub get` to install the package.
Or directly install the package by running:
```bash
flutter pub add logto_dart_sdk
```
Check out the package on [pub.dev](https://pub.dev/packages/logto_dart_sdk).
## Setup
- iOS: No additional setup required.
- [Android](https://github.com/ThexXTURBOXx/flutter_web_auth_2?tab=readme-ov-file#android).
- [Web](https://github.com/ThexXTURBOXx/flutter_web_auth_2?tab=readme-ov-file#web)
Learn more about the [flutter_web_auth_2 setup](https://github.com/ThexXTURBOXx/flutter_web_auth_2?tab=readme-ov-file#setup).
## Usages
### Init Logto SDK
```dart
final logtoConfig = const LogtoConfig(
endpoint: "",
appId: ""
);
void _init() {
logtoClient = LogtoClient(
config: logtoConfig,
httpClient: http.Client(), // Optional http client
);
render();
}
```
### Sign in and sign out
```dart
// Sign in
await logtoClient.signIn(redirectUri);
// Sign out
await logtoClient.signOut(redirectUri);
```
### Full SDK documentation
Check [Flutter SDK guide](https://docs.logto.io/quick-starts/flutter) for more details.
## Supported platforms
iOS, Android, Web
## Migration guide
:::note
For SDK version before 3.0.0, this SDK uses the [flutter_web_auth](https://pub.dev/packages/flutter_web_auth) package.
:::
1. Upgrade to the latest version
```yaml
dependencies:
logto_dart_sdk: ^3.0.0
```
2. Update the manifest files (Android platform only)
Replace the flutter_web_auth callback activity with the new `flutter_web_auth_2` in the AndroidManifest.xml file.
- FlutterWebAuth -> FlutterWebAuth2
- flutter_web_auth -> flutter_web_auth_2
3. `redirectUri` parameter is now required for the `signOut` method.
```dart
await logtoClient.signOut(redirectUri);
```
