When i press a butoon i just want to send some text from flutter to my node js app.
I want to send "text2" to a node js app using http.dart
When i press my raised button i want it to send an http string with the variable text 2 to a node js app.
i'd like to get a link of a tutorial do that or just some help, bc i don't find anything on the web, thx.
My flutter code :
import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
void main() {
runApp(new MyApp());
}
var text2;
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Bot Discord App',
theme: new ThemeData(
primarySwatch: Colors.blue,
primaryColor: const Color(0xFF2196f3),
accentColor: const Color(0xFF2196f3),
canvasColor: const Color(0xFFfafafa),
),
home: new MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key}) : super(key: key);
@override
_MyHomePageState createState() => new _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
final myController = TextEditingController();
@override
void dispose() {
// Clean up the controller when the widget is disposed.
myController.dispose();
super.dispose();
}
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text('Bot Discord App'),
),
body:
new Column(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
new SizedBox(
width: 100.0,
height: 100.0,
child:
new Padding(

new Text(

),
new TextField(

]
),
padding: const EdgeInsets.all(10.0),
),
),
new SizedBox(
width: 100.0,
height: 50.0,
child:
new Padding(
child:
new RaisedButton(key:null,
onPressed: () {
return
text2 = Text(myController.text) as String;
},
color: const Color(0xFFe0e0e0),
child:
new Text(
"UPDATE",
