AlertDialog does not display body text-CodePudding

I am using an AlertDialog() to display a dialog for about in my app. I tried, adding html text to my Strings resource. And I am accessing this below. But, for some unknown reason nothing is rendering out. Text is just some simple lorem ipsum.

AlertDialog(
            onDismissRequest = {
                tosVisible = false
            },
            icon = { Icon(Icons.Filled.Favorite, contentDescription = null) },
            title = {
                Text(text = "About this app")
            },
            text = {
                SelectionContainer{
                    TextView(context).setText(Html.fromHtml(stringResource(R.string.about_app), Html.FROM_HTML_MODE_COMPACT))
                }
            },
            confirmButton = {
                TextButton(
                    onClick = {
                        tosVisible = false
                    }
                ) {
                    Text("Confirm")
                }
            },
            dismissButton = {
                TextButton(
                    onClick = {
                        tosVisible = false
                    }
                ) {
                    Text("Dismiss")
                }
            }
        )

Output:

Solution:

Text(modifier = Modifier.verticalScroll(rememberScrollState()),
     text = Html.fromHtml(stringResource(R.string.about_app), Html.FROM_HTML_MODE_COMPACT).toString())

Use Text under compose. Instead of TextView.

Try this tutorial i found in javatPoint

import 'package:flutter/material.dart';  
  
void main() => runApp(MyApp());  
  
class MyApp extends StatelessWidget {  
  @override  
  Widget build(BuildContext context) {  
    final appTitle = 'Flutter Basic Alert Demo';  
    return MaterialApp(  
      title: appTitle,  
      home: Scaffold(  
        appBar: AppBar(  
          title: Text(appTitle),  
        ),  
        body: MyAlert(),  
      ),  
    );  
  }  
}  
  
class MyAlert extends StatelessWidget {  
  @override  
  Widget build(BuildContext context) {  
    return Padding(  
      padding: const EdgeInsets.all(20.0),  
      child: RaisedButton(  
        child: Text('Show alert'),  
        onPressed: () {  
          showAlertDialog(context);  
        },  
      ),  
    );  
  }  
}  
  
showAlertDialog(BuildContext context) {  
  // Create button  
  Widget okButton = FlatButton(  
    child: Text("OK"),  
    onPressed: () {  
      Navigator.of(context).pop();  
    },  
  );  
  
  // Create AlertDialog  
  AlertDialog alert = AlertDialog(  
    title: Text("Simple Alert"),  
    content: Text("This is an alert message."),  
    actions: [  
      okButton,  
    ],  
  );  
  
  // show the dialog  
  showDialog(  
    context: context,  
    builder: (BuildContext context) {  
      return alert;  
    },  
  );  
}
