Unhandled Exception: MissingPluginException

[mateusz-grzegorzek]

Hello,

I was trying to run simple application with url_launcher plugin and it crashed with following exception:

[ERROR:engine/src/flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: MissingPluginException(No implementation found for method canLaunch on channel plugins.flutter.io/url_launcher)
#0      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:157:7)
<asynchronous suspension>
#1      MethodChannel.invokeMethod (package:flutter/src/services/platform_channel.dart:332:12)
#2      MethodChannelUrlLauncher.canLaunch (package:url_launcher_platform_interface/method_channel_url_launcher.dart:18:21)

In README I found:

You can now theoretically run every flutter app you want using flutter-pi, including apps using extensions & plugins, 
just that you'd have to build the platform side of the plugins you'd like to use yourself.

So how can I build this platform side of the plugin and then use it with flutter-pi?
I see that url_launcher have linux platform code, so I need to somehow port this code to RPi?

Thanks in advance!

You can't open multiple windows on headless linux. That's the thing about flutter-pi: there's only one window, which is flutter-pi. There's no window manager running in the background (Wayland or X11) like in desktop linux. If you want multiple windows, you may have better luck with the official linux desktop embedding.
