class MyApp extends StatelessWidget {

  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  [@override](/user/override)
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Demo Home Page'),
      ),
      body: SafeArea(
        child: Container(
          padding: EdgeInsets.all(8.0),
          child: Column(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: <Widget>[
              UrlText(

              ),
              SizedBox(height: 20),

              SizedBox(height: 20),
              UrlText(

                style: TextStyle(color: Colors.green),
              ),
              SizedBox(height: 20),

              SizedBox(height: 20),

                urlStyle: TextStyle(
