Imports not working

[KPS250]

Facing issues when we try to import custom widgets and library dependency imports.
Importing custom button widget gives error: import 'button.dart';

EvalExample.dart

import 'package:flutter/material.dart';
import 'package:flutter_eval/flutter_eval.dart';

class EvalExample extends StatelessWidget {
  const EvalExample({super.key});

  @override
  Widget build(BuildContext context) {
    return const CompilerWidget(
      packages: {
        'example': {
          'main.dart': '''
           import 'package:flutter/material.dart';
           import 'button.dart';
            
            class MyApp extends StatelessWidget {
            
              @override
              Widget build(BuildContext context) {
                return Scaffold(

                    ),
                  ),
                );

[ali-1989]

I have this issue.

[thePrivacyFanatic]

also having this and need to know if this can be bypassed
(sorry i need to know wether to give up on this quickly)

ok edit:

1. maybe you should add button.dart near main.dart and see if that works
2. turns out it happens for me even without any import
   both of these make me think this is not an import issue
