starlight_dart_socket_io is a dart base socket server that can be used as socket io.
Add starlight_dart_socket_io as dependency to your pubspec file.
starlight_dart_socket_io:
git:
url: https://github.com/YeMyoAung/starlight_dart_socket_io.gitNo additional integration steps are required for Android and Ios.
First of all you need to import our package.
import 'package:starlight_dart_socket_io/starlight_dart_socket_io.dart';And then you can use easily.
You can create a socket io server by invoking StarlightSocketIo.
final StarlightSocketIo socketIo = StarlightSocketIo(
host: '127.0.0.1',
port: 8080,
);You can check whether your server is created or not by checking isCreated
socketIo.isCreated;You can check your clients count by using users
socketIo.users;You can check your rooms by using rooms
socketIo.rooms;You can listen with on method
socketIo.on('connection', (socket) {
print("new user connect ${socket.id}");
socket.on('_counter', (socket) {
print("_counter $socket");
socketIo.sockets.emit('_counter', socket);
});
});You can also emit all users or user by using emit
socketIo.sockets.emit("_counter",1);
socket.emit("_counter",1);You can close your connection by using close
socketIo.close();
socket.close();import 'package:starlight_dart_socket_io/starlight_dart_socket_io.dart';
void main(List<String> args) {
final StarlightSocketIo socketIo = StarlightSocketIo(
host: '192.168.1.5',
port: 8080,
);
socketIo.on('connection', (socket) {
print("new user connect ${socket.id}");
socket.on('disconnect',(data){
socket.close();
});
socket.emit('_counter', 1);
socket.on('_counter', (data) {
print("_counter $data");
socketIo.sockets.emit('_counter', socket);
});
});
socketIo.close();
socketIo.sockets.emit('_counter', 1);
