Enum PageTransitionsBuilder 

pub enum PageTransitionsBuilder {
    Zoom,
    Cupertino,
    FadeForwards,
}

One of the reference’s page transitions.

Variants

Zoom

The page zooms in from 85 % over a scrim, the one under it grows a little; popping, the page shrinks away and fades (ZoomPageTransitionsBuilder). What the desktops use by default, and what a platform with no builder falls back to.

Cupertino

The page slides in from the end edge while the one under it drifts a third of the way towards the start, as iOS pages do (CupertinoPageTransitionsBuilder).

FadeForwards

The page slides a quarter of the way in as it fades in, and the one under it a quarter of the way out as it fades out, as Android’s own pages do (FadeForwardsPageTransitionsBuilder). What Android uses when no back gesture is under way.

Implementations

impl PageTransitionsBuilder

pub fn transition_duration(self) -> f32

How long a push or a pop takes, in seconds: 300 ms for the zoom, 500 for the iOS slide, 450 for the fade (page_transitions_builder.dart:66, route.dart:155, page_transitions_theme.dart:470).

pub fn frame( self, progress: f32, forward: bool, gesture: bool, ) -> TransitionFrame

What is painted progress of the way through a transition, 0 being the old page at rest and 1 the new one. forward is a push; otherwise a pop, where the top page is the one leaving. gesture is a finger dragging a pop: the motion follows it linearly, as the reference’s does while a pop gesture is under way.
