DoesHandlePlatformMessageOnPlatformThread()

virtual bool flutter::PlatformViewEmbedder::EmbedderPlatformMessageHandler::DoesHandlePlatformMessageOnPlatformThread ( ) const

inlinevirtual

Returns true if the platform message will ALWAYS be dispatched to the platform thread.

Platforms that support Background Platform Channels will return false.

Implements flutter::PlatformMessageHandler.

Definition at line 34 of file platform_view_embedder.cc.

                                                                 {
    return true;
  }

HandlePlatformMessage()

virtual void flutter::PlatformViewEmbedder::EmbedderPlatformMessageHandler::HandlePlatformMessage ( std::unique_ptr< PlatformMessage >  message )

inlinevirtual

Ultimately sends the PlatformMessage to the host platform. This method is invoked on the ui thread.

Implements flutter::PlatformMessageHandler.

                                                                             {
    platform_task_runner_->PostTask(fml::MakeCopyable(
        [parent = parent_, message = std::move(message)]() mutable {
          if (parent) {
            parent->HandlePlatformMessage(std::move(message));
          } else {
            FML_DLOG(WARNING) << "Deleted engine dropping message on channel "
                              << message->channel();
          }
        }));
  }

InvokePlatformMessageEmptyResponseCallback()

virtual void flutter::PlatformViewEmbedder::EmbedderPlatformMessageHandler::InvokePlatformMessageEmptyResponseCallback ( int  response_id )

inlinevirtual

Performs the return procedure for an associated call to HandlePlatformMessage where there is no return value. This method should be thread-safe and able to be invoked on any thread.

Implements flutter::PlatformMessageHandler.

InvokePlatformMessageResponseCallback()

virtual void flutter::PlatformViewEmbedder::EmbedderPlatformMessageHandler::InvokePlatformMessageResponseCallback ( int  response_id, std::unique_ptr< fml::Mapping >  mapping  )

inlinevirtual

Performs the return procedure for an associated call to HandlePlatformMessage. This method should be thread-safe and able to be invoked on any thread.

Implements flutter::PlatformMessageHandler.
