How to use own firebase_core_linux plugin

[mateusz-grzegorzek]

Hello again,

I've create an initial firebase_core_linux plugin
based on url_launcher_linux plugin.
But I don't know how to call MethodChannel initializeCore.
When running flutter-pi it crashed with:

flutter: Observatory listening on http://127.0.0.1:33735/fASSxqf3JC4=/
[ERROR:engine/src/flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: MissingPluginException(No implementation found for method Firebase#initializeCore on channel plugins.flutter.io/firebase_core)

Do you want to use flutter-pi or the official linux desktop embedding? Since you're using GTK and flutter_linux headers in your plugin, neither of which are present in flutter-pi. The whole flutter plugin API is not present in flutter-pi.

If you want to add native code to flutter-pi, you need to write it inside flutter-pi. See the src/plugins directory. So just create a fork and write your plugin in there. I know, that's suboptimal and isn't really "compliant" with the flutter way of doing things, but there's no better solution.
