BroadcastChannel is not a type.

[jay-athelas]

I am trying to use the BroadcastChannel api , to send communication between a service worker and the main thread. Our app is hybrid, currently support web, ios and android.

Even when importing from import 'package:universal_html/html.dart'; I get a compilation error when trying to build for ios, stating that BroadastChannel is not a type. I can click on it and see the definition in html_dart2js.dart. What is going on here?

To replicate:

• Import universal html
• Use BroacastChannel BroadcastChannel? _channel;
• Compile for ios

You can use 1 of the following 2 ways:

1. Use of conditional imports/exports

• Create 'broadcast_channel_stub.dart' to use for mobile:

class BroadcastChannel {
   final String name;

   BroadcastChannel(this.name);

   Stream<dynamic> get onMessage => const Stream.empty();
}

• Create 'broadcast_channel_web.dart' to use for web:

export 'dart:html' show BroadcastChannel;

• Create 'broadcast_channel.dart' to use for all platforms:

export 'broadcast_channel_stub.dart' if (dart.library.html) 'broadcast_channel_web.dart';

2. Wait for PR #97 to be merged for use.
