I was learning Flutter web. Now I want to deploy this code in the real server. The flutter code here: in the lib folder
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter layout demo',
home: Scaffold(
appBar: AppBar(
title: Text('Flutter layout demo'),
),
body: Center(
child: Text('Hello World'),
),
),
);
}
}
How can I deploy this code on the server ? I am new on the Flutter web.
[UPDATE]
To create a production build for web, you can now directly run flutter build web
command similar to other platforms (android and ios)
and you will see build/web
folder generated with the assets folder and you can simply deploy it on your server.
[OLD ANSWER STEP 1 & 2 No longer required ]
you need to do a production build by using a webdev
tool,
To install webdev
you need a pub tool.
so go to the location where you have dart SDK
installed and inside the bin folder you should have a pub batch file. You need to provide the bin folder's path to the environment variable in order to use pub from cmd.
open cmd/terminal run the below command to install webdev
pub global activate webdev
now go to the root folder of your project and do a build in release mode
flutter build web
you should see a build folder (/build/web
) in the root directory, just copy that folder and host it on a web server.
I used the same way to deploy it to GitHub pages here's how in detail guide.
Some useful link: https://dart.dev/tools/webdev#build
Here's the running flutterweb app
You can deploy your flutter web app in a shared hosting with Nodejs or in VPS server with Python Follow this Medium Blog Post
After you build your flutter web app with "flutter build web" and you want to host it in a shared hosting plan prepare your nodejs app as a simple server for your flutter web app here is sample code
app.js
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var app = express();
app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public-flutter')));
module.exports = app;
package.json
{
"name": "flutter-web-app",
"version": "0.0.0",
"private": true,
"scripts": {
"start": "node ./bin/www"
},
"dependencies": {
"cookie-parser": "~1.4.4",
"debug": "~2.6.9",
"express": "~4.16.1",
"morgan": "~1.9.1"
}
}
Create a folder and name it (“public-flutter”) and then put your flutter web app in the folder you have just created so nodejs can serve it through his server if you are in a shared hosting just continue with the Blog Post here
and if you are in a VPS server then run this command if you want to server the nodejs app
node app.js
or if you don't want nodejs just use python in your flutter web app to serve it as a simple http server with this command
nohup python -m SimpleHTTPServer 8000 &
Just make sure you are in your web app folder when you run the command. “nohub” will let the command keep running even if you closed the SSH session on Linux . Or you can server your app through Dart pub/webdev tools by using the dhttpd package.
if you want to use your own server over web e.q your virtual private host or other host over net :
go to the root folder of your project and do a build in release mode flutter build web
,then
upload (/build/web)
directory to your server ,
you can follow this link and configure IIS on windows server.
