@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),

class MyHomePage extends StatefulWidget {

final String title;

}

class _MyHomePageState extends State<MyHomePage> {
final TextEditingController _textEditingController = TextEditingController();

String? url;

@override
void initState() {
_textEditingController.addListener(() {
// `getUrls` is a util function used to search for urls in a given text
String? url = getUrls(_textEditingController.text).firstOrNull;
// By default, a change event is fired when the user taps different parts of the text field. So we ensure we're only setting the url when a user changes the first url text and not any other text
if (this.url != url) {
setState(() {
this.url = url;
});
}
});
super.initState();
}

@override
Widget build(BuildContext context) {
return Scaffold(

backgroundColor: Theme.of(context).colorScheme.inversePrimary,
title: Text(widget.title),
),
body: SingleChildScrollView(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
if (url != null) LinkPreviewTile(url: url!),
Container(
padding: const EdgeInsets.all(20),
margin: const EdgeInsets.symmetric(horizontal: 10),
decoration: BoxDecoration(
color: Theme.of(context).primaryColor,
borderRadius: BorderRadius.circular(20),
