![]() ![]() We'll remove some default code and add the simple MaterialApp pointing to the empty Container as a home page for now: import 'package:flutter/material. the conversation screen, which we are going to implement as a separate page, andįirst, we need to make some simple configurations to the default boilerplate code in the main.dart file.The Main Home Screen will contain 2 sections: Now, we are going to start building the UI for our chat application. If everything is properly set up, then in order to create a project we can simply run the following command in our desired local directory: flutter create ChatAppĪfter we've set up the project, we can navigate inside the project directory and execute the following command in the terminal to run the project in either an available emulator or an actual device: flutter runĪfter it's been successfully built, we will get the following result in the emulator screen: How to Create the Main Home Screen UI For that, make sure that you've installed the Flutter SDK and other Flutter app development-related requirements. So, let's get started! How to Create a New Flutter Projectįirst, we need to create a new Flutter project. Along with learning the awesome Chat UI implementation in Flutter, we will also learn how its coding workflows and structures work. In this tutorial, I am going to introduce you to a mix of both: we're going to build a chat app UI entirely on the Flutter/Dart coding environment. You can use it to create pixel-perfect UIs, and many development companies use Flutter today. ![]() The user interface (or UI) is the most impactful aspect of the overall user experience, so it's important to get right.įlutter app development has taken the world by storm in terms of cross-platform mobile application development. There is also high demand for intuitive and powerful user interfaces with state of the art features. This makes these messaging applications an essential medium of communication. Then create a StatefulWidget named ChatWidget this will contain the code for your chat application.These days, many people use chat applications to communicate with team members, friends, and family via their smart phones. Import 'package:socket_io_client/socket_io_client.dart' as IO Now update the file, and import the socket.io client import 'package:flutter/material.dart' Open the lib/main.dart file and delete everything in that file. Step 8: Importing Socket.io client in Flutter Run the above command to install the dependency. On the Server we are using socket.io so we will have to install socket_io_client package in the Flutter App to connect to our socket.io server. We have our backend ready now, we need to build our app that will connect to our backend to send and receive messages. We can start the chat backend by running the command node index.js Step 7: Setting up the Flutter App Sending the new message to call the connected clients RedisClient.lpush("chat_messages", JSON.stringify(newMessage)) ![]() Saving message in redis in list named "chat_messages" Id: uuidv4(), // Generating a unique id for the messageĬreated: new Date().getTime(), // Creating timestamp for the message If message is valid, then creating a new message object If the message is invalid, then sending errorĬonsole.log("Invalid message, error occurred", error) Get 222 flutter chat plugins, code & scripts on CodeCanyon such as Qertsa - Flutter Chat App UI Template, Flutter Chat App With Firebase Firestore Database. We will design a very simple model to store our chat messages = chatMessageSchema.validate(data) In this guide, we will build a chat application from scratch including the Flutter App and the Node.JS backend for our Flutter Chat application. Building Chat App from Scratch with Custom Backend If you want to learn how to launch a simulator you can learn more about it here Launching iOS Simulator and Launching Android Simulator. This will launch the application in iOS or Android simulator, but you need to have the simulator running. To run our flutter application we will type the command flutter run flutter create my_chat_appĪfter scaffolding the application we will cd into our application directory and launch the project in vscode. We will run the following command to scaffold a starter flutter application. If you don't have the Flutter Cli setup follow the Getting Started Guide on the flutter official website and setup your Flutter development environment. We first need to scaffold our application, we will use the flutter cli to scaffold our application. So now let's get started in building our chat application in Flutter without using Firebase. ![]()
