# Famedly Matrix SDK
Matrix SDK for the famedly talk app written in dart.
## Native libraries
For E2EE, libolm must be provided.
Additionally, OpenSSL (libcrypto) must be provided on native platforms for E2EE.
For flutter apps you can easily import it with the [flutter_olm](https://pub.dev/packages/flutter_olm) and the [flutter_openssl_crypto](https://pub.dev/packages/flutter_openssl_crypto) packages.
## API
The API is documented here: [famedly.gitlab.io/famedlysdk/](https://famedly.gitlab.io/famedlysdk/)
## How to use this
1. Import the sdk
```yaml
famedlysdk:
git:
url: https://gitlab.com/famedly/famedlysdk.git
```
```dart
import 'package:famedlysdk/famedlysdk.dart';
```
2. Create a new client:
```dart
final client = Client("HappyChat");
```
The SDK works better with a Moor database. Otherwise it has no persistence. [Take a look here for an example store](https://gitlab.com/famedly/fluffychat/-/tree/main/lib/utils/database).
3. Connect to a Matrix Homeserver and listen to the streams:
```dart
client.onLoginStateChanged.stream.listen((bool loginState){
print("LoginState: ${loginState.toString()}");
});
client.onEvent.stream.listen((EventUpdate eventUpdate){
print("New event update!");
});
client.onRoomUpdate.stream.listen((RoomUpdate eventUpdate){
print("New room update!");
});
try {
await client.checkHomeserver("https://yourhomeserver.abc");
await client.login("username", "password");
}
catch(e) {
print('No luck...');
}
```
4. Send a message to a Room:
```dart
await client.getRoomById('your_room_id').sendTextEvent('Hello world');
```
