Error: dart library ‘dart:ui’ is not available on this platform

Error: dart library ‘dart:ui’ is not available on this platform

Explanation:

This error occurs when you are trying to use the ‘dart:ui’ library in a platform where it is not available. The ‘dart:ui’ library provides access to low-level and platform-specific code for building user interfaces.

However, ‘dart:ui’ is only available for use in Flutter projects, which are specifically designed for building cross-platform mobile applications. If you are encountering this error outside of a Flutter project, it means that you are trying to use Flutter-specific code in a non-Flutter environment.

Example:

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Dart UI Error Example'),
        ),
        body: Center(
          child: Text(
            'Hello World',
            style: TextStyle(fontSize: 24),
          ),
        ),
      ),
    );
  }
}

In the above example, we have a simple Flutter app that displays a ‘Hello World’ message. The ‘dart:ui’ library is not required here because we are not using any advanced platform-specific features.

If you are not working with Flutter and still encountering this error, make sure you are not using any Flutter-specific code or libraries that rely on ‘dart:ui’ in your non-Flutter project.
