Register plugin from isolate

[Galeen]

If I want to use another plugin that starts in isolate and auto register plugins(like foreground service), there is an issue.
The problem is that flt_worker requires an activity and crashes on registration, which leads to registering only the plugins that was before it in the GeneratedPluginRegistrant
The problem is here :

          final MethodChannel channel = new MethodChannel(registrar.messenger(), CHANNEL_NAME);
          channel.setMethodCallHandler(new FltWorkerPlugin(registrar.activity()));

I have changed it manually on my side to :

    try {
          final MethodChannel channel = new MethodChannel(registrar.messenger(), CHANNEL_NAME);
          channel.setMethodCallHandler(new FltWorkerPlugin(registrar.activity()));
      } catch (Exception e) {
          Log.e("Error","FltWorkerPlugin.registerWith", e );
      }

And now can see the crash in the logs, but is handled and GeneratedPluginRegistrant can continue with the other plugins. Also I don't use flt_worker from other isolates and above approach is saving me

Btw, I haven't checked if your plugin really needs an activity? If not you can pass a context only. Bellow code does not log a crash when is started from another isolate and also works when I tested it in my app

  public static void registerWith(Registrar registrar) {
      try {
          final MethodChannel channel = new MethodChannel(registrar.messenger(), CHANNEL_NAME);
          channel.setMethodCallHandler(new FltWorkerPlugin(registrar.context()));
      } catch (Exception e) {
          Log.e("Error","FltWorkerPlugin.registerWith", e );
      }
  }
