NSLocale objectForKey: may return nil for NSLocaleLanguageCode and
NSLocateCountryCode in certain cases.
This adds a defensive nil check for such cases.
Place all iOS code that relies on APIs introduced in iOS versions later
than our base SDK version (iOS 8) behind @available checks. This allows
us to enable the -Wunguarded-availability compiler flag for iOS builds
in the buildroot repo.
This reverts commit 89b6d435205d9bcdf8dde965dd1b0432482407c5.
Apparently the clang toolchain is still hitting issues. Will give this
another go after the next clang toolchain update.
Guard code that deals with iOS safe area insets behind an @available
check.
This cleans up some old TODOs from before out clang toolchain supported
@available.
This change ensures that touches are mapped to the Flutter view
co-ordinate system. In the case of a Flutter view that doesn't share the
same origin and orientation as the screen co-ordinate system, touches
were appled in the wrong location. This bug affected Flutter views whose
origin was not the screen origin and Flutter apps running with the
in-call status bar on iPhones other than the iPhone X.
This adds support for scrolling the primary scroll view to the top on
status bar touches, on the iPhone X.
Notes:
1. The iPhone X status bar doesn't change height when in in-call/etc.
mode, and unlike other iPhones, does scroll to top when in in-call mode.
2. No matter which model of iOS device, the top safe area inset doesn't
change when in in-call mode. In in-call mode, the OS reduces the app
view height by 20px off the top, and the double-height 'in-call' status
bar covers this new inset (outside the view) and there continues to be a
20px safe area in the app.
On iOS 11, rather than comparing status bar height to a hardcoded 20px
'standard height' we now compare to the top safe area inset (which is
always the standard status bar height, regardless of device). On iOS
versions prior to iOS 11, we use the previous logic.
Fixesflutter/flutter#13439
Keyboard height is now treated as a view inset, which could be used to
shrink the content area of the app as is done in the Material Scaffold,
rather than padding, which is used to indicate content areas where user
interaction should be avoided.
This allows for us to start migrating framework classes (notably
Scaffold) to use window.viewInsets.bottom to get the keyboard height.
Once framework updates have landed, we will land an engine patch to
expose the iOS bottom safe area inset as padding.
This change is already landed for Android.
Related issue: flutter/flutter#12098
Previously, we failed to clear/update the mark text range on updates
from the framework. This resulted in a crash if the incoming text value
was shorter than the current mark range when iOS attempts to extract the
mark range substring from the text.
Fixesflutter/flutter#12585
Window.viewInsets is the set of window-relative insets that describe the
area of the window that an application may want to treat as effectively
reducing the size of the content. Typically this is due to system UI
that fully obscures underlying content, such as the keyboard.
This area differs from padding in that padding is the set of insets that
describe the area of the window that may be partially (or fully)
obscured by system UI or physical intrusions into the view area (e.g.
iPhone X sensor housing, status bar, or the iPhone X home indicator
widget).
This patch does not yet enable the iOS bottom edge safe area. Once the
framework has been updated to use viewInsets for bottom-edge occlusions
(today, the keyboard), the bottom safe area will be enabled and
framework patches that depend on it, landed.
With the update to HEAD of the Fuchsia buildtools repo, the new clang
toolchain picked up caused link-time breakage in android x86_64
libFlutter.so builds.

This reverts commit 8ad42f0dae3cb1267c2b9ab99db80e4696ddbc3d.
* Roll Fuchsia buildtools to 85907c59e97527d79bbfdfd849d8e85c24959cc5
This also updates Flutter buildroot to a6e52dbb776c45cc8c57d7143b8eb8b2e762fdfb
which disables -Wtautological-constant-compare temporarily until
https://reviews.llvm.org/D39462 lands in clang. This is in line with
Fuchsia's compiler options.
* Apply clang-format diffs
No logical changes. This applies clang-format from the latest Fuchsia
buildtools to the engine codebase.
There are two different sets of view insets that applications may want
to track in order to avoid unwanted interaction with system UI:
1. OS UI that effectively shrinks the Flutter view from a UX point of
view: e.g., when the keyboard opens, it occludes the bottom of the
screen and the view should be adjusted such that the bottom, for the
purposes of scrolling is just above the keyboard.
2. OS UI that is overlaid over the application, but into which the
application should draw. e.g., the Home indicator on the iPhone X
typically appears near the bottom of the screen, overlaid over app
content. Content should be rendered within this 'safe area' but apps
should avoid requiring user interaction there. For example, list
views may want to include some small amount of additional padding to
ensure the last list item can scroll above this area.
Since Flutter does not currently distinguish between these two cases,
this patch disables the bottom safe area inset until API is added to
support these separately.
This change exposes the view safe area insets (introduced in iOS 11) to
the framework via MediaQuery.of(context).padding. Safe area insets are
the view insets (padding) inside of which content can be relied on to
display without truncation/clipping, as would occur with e.g. the iPhone
X sensor notch.
As this API was added in iOS 11, we place it behind a runtime guard
checking OS level.
Until the runtime support for @avialable lands in the next Fuchsia
buildtools rev, ignore -Wunguarded-availability-new around the safe area
insets check and use an FML runtime check instead.
