◆ fl_mouse_cursor_channel_new()

FlMouseCursorChannel * fl_mouse_cursor_channel_new	(	FlBinaryMessenger *	messenger,
		FlMouseCursorChannelVTable *	vtable,
		gpointer	user_data
	)

fl_mouse_cursor_channel_new: @messenger: an #FlBinaryMessenger. @vtable: callbacks for incoming method calls. @user_data: data to pass in callbacks.

Creates a new channel that implements SystemChannels.mouseCursor from the Flutter services library.

Returns: a new #FlMouseCursorChannel.
