Blur text inside a container

Here is an example, of how to blur text inside a container.

import 'dart:ui';

import 'package:flutter/material.dart';

main(List<String> args) {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @
override

  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(body: MyHomePage()),
    );
  }
}

class MyHomePage extends StatelessWidget {
  @
override

  Widget build(BuildContext context) {
    return Center(
        child: ImageFiltered(
      imageFilter: ImageFilter.blur(sigmaX: 8, sigmaY: 8),
      child: Container(
        color: Colors.green,
        child: Text(
          'Hello World!',
          style: TextStyle(fontSize: 50),
        ),
      ),
    ));
  }
}

Thanks,
