v2.0.1 throws MissingPluginException and crashes on Android

[davejlin]

MissingPluginException is thrown and crashes my app when I use v2.0.1 on Android. v2.0.0 on Android does not have this issue. v2.0.1 on iOS does not have this issue. Is there something I need to update to use v2.0.1 on Android?

Exception has occurred.
MissingPluginException (MissingPluginException(No implementation found for method getPage on channel flutter_plugin_pdf_viewer))

There is the error you mention, and also there should be a else block after the if here:

                               if (pageResult == null) {
                                    Log.d(TAG, "Retrieving page failed.");
                                    result.notImplemented();
                                }
                                mainThreadHandler.post(new Runnable() {
                                    @Override
                                    public void run() {
                                        result.success(pageResult);
                                    }
                                });
