◆ fl_view_renderer_notify_frame()

void fl_view_renderer_notify_frame ( FlViewRenderer *  renderer)

fl_view_renderer_notify_frame: @renderer: an #FlViewRenderer.

Notifies that a frame has been rendered. Subclasses call this on each frame. The "first-frame" signal is emitted on the first call.

fl_view_renderer_paint_background: @renderer: an #FlViewRenderer. @cr: a #cairo_t to paint to.

Paints the background color behind the Flutter frame. Subclasses call this at the start of their draw implementation.
