Trait RendererBindingOverridesObject 

pub trait RendererBindingOverridesObject: Sized + 'static {
    // Required methods
    fn will_draw_frame(self: Handle<Self>, app: &mut App);
    fn did_draw_frame(self: Handle<Self>, app: &mut App);

    // Provided method
    fn did_handle_metrics_changed(self: Handle<Self>, app: &mut App) { ... }
}

The object side of Flutter’s WidgetsBinding overrides of RendererBinding.drawFrame: the widget layer builds before the renderer’s frame and finalizes its tree after it. Implement it on the binding above and register Rc::new(handle) with RendererBinding::set_overrides; Handle<T> is then RendererBindingOverrides.

Required Methods

fn will_draw_frame(self: Handle<Self>, app: &mut App)

Runs at the start of RendererBinding::draw_frame, before layout.

fn did_draw_frame(self: Handle<Self>, app: &mut App)

Runs at the end of RendererBinding::draw_frame, after compositing.

Provided Methods

fn did_handle_metrics_changed(self: Handle<Self>, app: &mut App)

Runs at the end of RendererBinding::handle_metrics_changed: Flutter’s WidgetsBinding.handleMetricsChanged override, which tells its observers.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
