This repo contains sample code for Stream's Build Viking activity.
This to run this application, you must have the following:
- Flutter
1.24.0-7.0.preor higher installed - A Stream account
- An
api.dartfile inlib/containing the following:
class API {
static const apiUrl =
"YOUR_API_URL";
static const streamApi = "YOUR_STREAM_API_KEY";
}This project consists of two parts, the application (this repo) and a simple API that verifies a Flutter Viking ticket ID and creates a [Stream] user associated with that ID.
You can implement a custom API using the sample code below or remove it entirely by eliminating the call to __fetchUserAccount on line 20 of lib/services/api_service.dart. In its place, you can return an instance of VikingUser containing placeholder information.
Note, if you chose the latter, you would need to generate a user token manually using our online tool.
import { StreamChat } from 'stream-chat';
import axios from 'axios';
export const stream = async event => {
const data = JSON.parse(event.body);
try {
const res = await axios.get(`${process.env.TICKET_URL}${data.id}`, {
headers: {
Authorization: `Token token=${process.env.TICKET_SECRET}`,
'Content-Type': 'application/json',
},
});
const client = new StreamChat(process.env.STREAM_API_KEY, process.env.STREAM_API_SECRET);
const ticket = res.data.ticket;
const user = {
id: ticket.id.toString(),
name: ticket.name,
role: 'channel_member',
image: 'https://stream-blog-v2.imgix.net/blog/wp-content/uploads/35e4570ddc67c374f9dbbf57c743acaa/dash.png',
};
const token = client.createToken(user.id);
await client.upsertUser(user);
return {
statusCode: 200,
headers: {
'Access-Control-Allow-Origin': '*',
},
body: JSON.stringify({
data: {
token,
id: user.id,
name: user.name,
image: user.image,
},
}),
};
} catch (error) {
console.error(error);
return {
statusCode: error.response.status,
headers: {
'Access-Control-Allow-Origin': '*',
},
body: JSON.stringify({
message: error.message,
}),
};
}
};Finally, you can run the application using regular Flutter build commands.
- Run
flutter packages getto install the project dependencies - Launch the application in debug mode using
flutter run -d <name-of-your-device>
Happy Hacking!
