SuperTokens Flutter SDK

About

This is a Flutter SDK written in pure dart that is responsible for maintaining a SuperTokens session for a Flutter app.

Usage

Initialise the SDK

import 'package:supertokens_flutter/supertokens.dart';

// Initialise the SDK on app launch
void main() {
    SuperTokens.init(apiDomain: "http://localhost:3001");
}

Checking if a session exists

import 'package:supertokens_flutter/supertokens.dart';

Future<bool> doesSessionExist() async {
    return await SuperTokens.doesSessionExist();
}

Usage with http

Making network requests

You can make requests as you normally would with http, the only difference is that you import the client from the supertokens package instead.

// Import http from the SuperTokens package
import 'package:supertokens_flutter/http.dart' as http;

Future<void> makeRequest() {
    Uri uri = Uri.parse("http://localhost:3001/api");
    var response = await http.get(uri);
    // handle response
}

The SuperTokens SDK will handle session expiry and automatic refreshing for you.

Using a custom http Client

If you use a custom http client and want to use SuperTokens, you can simply provide the SDK with your client. All requests will continue to use your client along with the session logic that SuperTokens provides.

// Import http from the SuperTokens package
import 'package:supertokens_flutter/http.dart' as http;

Future<void> makeRequest() {
    Uri uri = Uri.parse("http://localhost:3001/api");

    // provide your custom client to SuperTokens
    var httpClient = http.Client(client: customClient)

    var response = await httpClient.get(uri);
    // handle response
}

Usage with Dio

Add the SuperTokens interceptor

You can make requests as you normally would with dio.

import 'package:supertokens_flutter/dio.dart';

void setup() {
    Dio dio = Dio(...)
    dio.interceptors.add(SuperTokensInterceptorWrapper(client: dio));
}

Or use instance method instead.

import 'package:supertokens_flutter/dio.dart';

void setup() {
  Dio dio = Dio();  // Create a Dio instance.
  dio.addSupertokensInterceptor();
}

Making network requests

import 'package:supertokens_flutter/dio.dart';

void setup() {
    Dio dio = Dio(...)
    dio.interceptors.add(SuperTokensInterceptorWrapper(client: dio));

    var response = dio.get("http://localhost:3001/api");
    // handle response
}

Signing out

import 'package:supertokens_flutter/supertokens.dart';

Future<void> signOut() async {
    await SuperTokens.signOut();
}

Getting the user id

import 'package:supertokens_flutter/supertokens.dart';

Future<String> getUserId() async {
    return await SuperTokens.getUserId();
}

Manually refresh sessions

import 'package:supertokens_flutter/supertokens.dart';

Future<void> manualRefresh() async {
    // Returns true if session was refreshed, false if session is expired
    var success = await SuperTokens.attemptRefreshingSession();
}
