## ◆ fl_view_new()

G_BEGIN_DECLS G_MODULE_EXPORT FlView* fl_view_new | ( | FlDartProject * | project | ) |

FlView:

#FlView is a GTK widget that is capable of displaying a Flutter application.

The following example shows how to set up a view in a GTK application: |[ FlDartProject *project = fl_dart_project_new (); FlView *view = fl_view_new (project); gtk_widget_show (GTK_WIDGET (view)); gtk_container_add (GTK_CONTAINER (parent), view);

FlBinaryMessenger *messenger = fl_engine_get_binary_messenger (fl_view_get_engine (view)); setup_channels_or_plugins (messenger); ]| fl_view_new: @project: The project to show.

Creates a widget to show a Flutter application.

Returns: a new #FlView.
