海外TECH	DEV Community	How you can use WebSockets with Flutter	https://dev.to/vibalijoshi/how-you-can-use-websockets-with-flutter-ipn	How you can use WebSockets with FlutterWebSockets are clearly taking the industry by storm With Google s Flutter framework on the rise too it would give you a big boost knowing how to integrate both of these technologies What are WebSocketsWebSockets represent a long awaited evolution in the client server web technology It defines a fully duplex bi directional communication channel between the client and server Related What do you mean by client and a server In simple words once after the initial handshake where the server and the client agree to upgrade to WebSockets from HTTP the client and the server can talk in real time without having to continuously make requests like loading the page again and again Only the client side problems of developing a dependable WebSocket based solution for realtime Flutter apps are discussed in this article On the server side you must determine which solution you wish to utilise You can use an open source library like Socket IO if you haven t already How to connect to a WebSocket server with Flutter web socket channel packageWe will use this package to acquire the tools we need to connect to a WebSocket server The web socket channel basically works with the StreamChannel class which is an abstract class representing a two way communication channel as in the case for WebSockets Each StreamChannel exposes a Stream for receiving data A Stream is like a pipe you put a value on the one end and if there s a listener on the other end that listener will receive that value It also exposes StreamSink used to push messages to the server In short words the package allows you to both listen for messages from the server and push messages to the server i e fully duplex bi directional communication channel InstallationFollow the installation given here Basic IdeaWe d have a textfield in our app where the user could type a message The data that we input would be displayed on the screen after pressing a button The data displayed comes from the server response which is an echo server in this case meaning it sends back what it receives These servers are used to determine whether or not a connection to a server is successful Here we would be using them to maintain simplicity for this example Here is the boiler plate we will be using How to connect to serverFirst let us connect to a WebSocket server As discussed above we will be using an echo webSocket server WebSocketChannel channel IOWebSocketChannel connect wss ws ifelse io WebSocketChannel A StreamChannel class representing a two way communication that communicates over a WebSocket IOWebSocketChannel A WebSocketChannel that communicates using a dart io WebSocket IOWebSocketChannel connect Creates a new WebSocket connection and connects to url using WebSocket connect and returns a channel that can be used to communicate over the resulting socket Here wss ws ifelse io is an echo WebSocket server Please note that the mostly used echo server ws echo websocket org is no longer in service How to listen to the serverNow that we ve established a connection let us listen to messages from the server After sending a message to the test server it sends the same message back echo We will use a StreamBuilder widget to listen for new messages and a Text widget to display them A StreamBuilder Can listen to exposed streams Return widgetsCatch snapshots of got stream information StreamBuilder stream widget channel stream builder context snapshot return Padding padding const EdgeInsets all child Text snapshot hasData snapshot data Watch this video to get a better idea about StreamBuilder How to Send data to the serverWe will add a function sendData responsible for sending data to the stream whenever the floating button is pressed void sendData if controller text isNotEmpty widget channel sink add controller text channel sink add for sending values to the other endpoint of the stream i e the server using the sink property of the WebSocketChannel To make sure we are printing not empty data we add a How to close the connection Using the close method we can disconnect from the server void dispose widget channel sink close super dispose Final Code If you successfully connected to the server then you would see this on the emulator This is how your app should would look at the end Where can you use it The realtime web existed before WebSockets but it was difficult to accomplish often slower and based on hacking web technologies that weren t built for realtime applications The WebSocket protocol paved the path for a genuinely real time web and expanded the possibilities of Internet communication USE CASES Web based gamesChatting Applications	2021-10-12 19:43:41
