This reverts commit
d24c01bd0c.
The original change was reverted because it caused some apps to get
stuck on the splash screen on some phones.
An investigation determined that this was due to a rounding error.
Example: The device reports a physical size of 1008.0 x 2198.0 with a
dpr of 1.912500023841858. Flutter would translate that to a logical size
of 527.0588169589221 x 1149.2810314243163 and use that as the input for
its layout algorithm. Since the constraints here are tight, the layout
algorithm would determine that the resulting logical size of the root
render object must be 527.0588169589221 x 1149.2810314243163.
Translating this back to physical pixels by applying the dpr resulted in
a physical size of 1007.9999999999999 x 2198.0 for the frame. Android
now rejected that frame because it didn't match the expected size of
1008.0 x 2198.0 and since no frame had been rendered would never take
down the splash screen.
Prior to dynamically sized views, this wasn't an issue because we would
hard-code the frame size to whatever the requested size was.
Changes in this PR over the original PR:
* The issue has been fixed now by constraining the calculated physical
size to the input physical constraints which makes sure that we always
end up with a size that is acceptable to the operating system.
* The `ViewConfiguration` was refactored to use the slightly more
convenient `BoxConstraints` over the `ViewConstraints` to represent
constraints. Both essentially represent the same thing, but
`BoxConstraints` are more powerful and we avoid a couple of translations
between the two by translating the` ViewConstraints` from the
`FlutterView` to `BoxConstraints` directly when the `ViewConfiguration`
is created.
All changes over the original PR are contained in the second commit of
this PR.
Fixes b/316813075
Part of https://github.com/flutter/flutter/issues/134501.
This PR adds `String? identifier` to `Semantics` and `SemanticsProperties`. The `identifier` will be exposed on Android as `resource-id` and on iOS as `accessibilityIdentifier`.
Mainly targeted at #17988

iOS Engine PR: https://github.com/flutter/engine/pull/48858
### Migration
This change breaks the SemanticsUpdateBuilder API which is on the Framework<-->Engine border. For more details see [engine PR](https://github.com/flutter/engine/pull/47961).
Steps:
part 1: [engine] add `SemanticsUpdateBuilderNew` https://github.com/flutter/engine/pull/47961
**part 2: [flutter] use `SemanticsUpdateBuilderNew`** <-- we are here
part 3: [engine] update `SemanticsUpdateBuilder` to be the same as `SemanticsUpdateBuilderNew`*
part 4: [flutter] use (now updated) `SemanticsUpdateBuilder` again.
part 5: [engine] remove `SemanticsBuilderNew`
Towards https://github.com/flutter/flutter/issues/134501.
This change is based on https://github.com/flutter/engine/pull/48090. It changes the `RenderView` to be dynamically sized based on its content if the `FlutterView` it is configured with allows it (i.e. the `FlutterView` has loose `FlutterView.physicalConstraints`). For that, it uses those `physicalConstraints` as input to the layout algorithm by passing them on to its child (after translating them to logical constraints via the device pixel ratio). The resulting `Size` that the `RenderView` would like to be is then communicated back to the engine by passing it to the `FlutterView.render` call.
Tests will fail until https://github.com/flutter/engine/pull/48090 has rolled into the framework.
* Adds `TestDisplay`
* Updates `TestPlatformDispatcher` to wrap all `Display`s and relate them to their appropriate `TestFlutterView`
* Updates `TestFlutterView` to tie `devicePixelRatio` to its display as per the documentation on `Display`
