Hello friend, I have corrected the code today 2024: import 'package:flutter/material.dart'; void main() => runApp(MyApp()); class MyApp extends StatelessWidget { const MyApp({super.key}); @override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter TextField Demo', theme: ThemeData( primarySwatch: Colors.blue, ), home: MyHomePage(title: 'Flutter TextField Demo'), ); } } class MyHomePage extends StatefulWidget { const MyHomePage({super.key, required this.title}); final String title; @override _MyHomePageState createState() => _MyHomePageState(); } class _MyHomePageState extends State<MyHomePage> { String _inputtext=''; TextEditingController inputtextField = TextEditingController(); void _processText() { setState(() { _inputtext = inputtextField.text; }); } @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text(widget.title), ), body: Center( child: Column( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ Padding( padding: const EdgeInsets.all(16.0), child: TextField( controller: inputtextField, decoration: InputDecoration( border: OutlineInputBorder(), labelText: 'Enter some text' ), ), ), Padding( padding: const EdgeInsets.all(16.0), child: Text( '$_inputtext', style: Theme.of(context).textTheme.headline5, ), ), ElevatedButton( onPressed: _processText, child: Text('Process Text'), ) ], ), ), ); } }
