# Why
When using the stack navigator on iOS, it takes a (too) long time before the `didFocus` and stack `onTransitionEnd` lifecycle events are triggered. The visual animation is typically completed well within 500 msec, but it takes around 1000 msec before the previously mentioned events are emitted. This causes problems with for instance `react-navigation-shared-element`, which relies on these events to fire in a timely manner(https://github.com/IjzerenHein/react-navigation-shared-element/issues/24)
# How
This PR updates the resting threshold so that the underlying spring settles faster. No visual differences or differences in smoothness were witnessed during testing.
## Before
Time to settle `didFocus`: **941**
Time to settle `stack.onTransitionEnd`: **924**
```
15:59:55.743 [ListViewStack]startTransition, closing: false, nestingDepth: 1
15:59:55.744 [ListViewStack]willFocus, scene: "DetailScreen", depth: 1, closing: false
15:59:55.745 Transition start: "ListScreen" -> "DetailScreen"
15:59:56.667 [ListViewStack]endTransition, closing: false, nestingDepth: 1
15:59:56.668 Transition end: "DetailScreen"
15:59:56.685 [ListViewStack]didFocus, scene: "DetailScreen", depth: 1
```
## After
Time to settle `didFocus`: **529**
Time to settle `stack.onTransitionEnd`: **512**
```
15:55:00.686 [ListViewStack]startTransition, closing: false, nestingDepth: 1
15:55:00.687 [ListViewStack]willFocus, scene: "DetailScreen", depth: 1, closing: false
15:55:00.687 Transition start: "ListScreen" -> "DetailScreen"
15:55:01.198 [ListViewStack]endTransition, closing: false, nestingDepth: 1
15:55:01.199 Transition end: "DetailScreen"
15:55:01.216 [ListViewStack]didFocus, scene: "DetailScreen", depth: 1
* Add padding bottom to ios presentation modal
Because of the translateY moving the screen out to the bottom of view by 10 pt, these 10pt are hidden under the screen, or steal this size from the safe area. To avoid cutting elements, the size of the screen could be decreased by the `topOffset` using padding on the bottom. Fixes#7856
* Update packages/stack/src/TransitionConfigs/CardStyleInterpolators.tsx
