	)

fl_view_monitor_new: @view: the view being monitored. @on_first_frame: the function to call when the first frame is rendered.

Helper class to allow the Flutter engine to monitor a FlView using FFI. Callbacks are called in the isolate this class was created with.

Returns: a new #FlViewMonitor.
