[How to use] Web deployment: Uncaught UnimplementedError

Hengry commented 3 months ago

Platforms

Web

Description

I've read the Web section on README, and I've already added <script src="https://unpkg.com/pica/dist/pica.min.js" ></script> in web/index.html. It runs well in my local including IOS and also web. But when I built and deployed, it always shows Uncaught UnimplementedError in console. Did I missed anything?

My code

import 'package:flutter_image_compress/flutter_image_compress.dart';
// ...
final result = await FlutterImageCompress.compressWithList(
  imageBytes,
  minHeight: 768,
);

  <body>
    <script src="https://unpkg.com/pica/dist/pica.min.js"></script>
    <script>
      window.addEventListener('load', function (ev) {
        // Download main.dart.js
        _flutter.loader.loadEntrypoint({
          serviceWorker: {
            serviceWorkerVersion: serviceWorkerVersion,
          },
          onEntrypointLoaded: function (engineInitializer) {
            engineInitializer.initializeEngine().then(function (appRunner) {
              appRunner.runApp();
            });
          },
        });
      });
    </script>
  </body>
</html>

Try do it

I've tried add <script src="https://unpkg.com/pica/dist/pica.min.js" ></script> on either head or body, also <script src="https://cdn.jsdelivr.net/npm/pica@9.0.1/dist/pica.min.js" ></script> on either head or body.

But none of them works.

Same here, local it works, once deployed it fails.

I just found out that my issue was related to brave browser shield, after turning shields down it worked without uncaught exceptions
