desktop_multi_window crashes with a Firebase project

[macwilko]

When adding firebase to the project, and creating a new window, the project will crash before rendering the new window.

The following error is logged:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)

@mattsrobot this happens because the instance of the Flutter Engine that corresponds to the new window doesn't get access to the plugins from the main instance. You need to write an interoperable layer that the windows can use to communicate with each other by way of the invokeMethod function.
