* Add indent option to logger and indent non-flutter nested output

* Add a missed override

* Formatting

Move the back button and drawer opening logic into the app bar.

Move the tap-status-bar-to-scroll-to-top logic to using
ScrollControllers. Provide a PrimaryScrollController and a `primary`
flag on scroll views.

Make it possible to track when a route becomes or stops being poppable.

* Allow for customization of hintText in InputField

* Adding tests.

* disables all `flutter test` and `flutter drive` tests on Windows as those two commands are not fully implemented on Windows yet
* fixes other failures on Windows

All clients have moved to PageView.

This manual test has used the PageView widget for a while already.

...for the case where there's no right or bottom padding.

Tabs are now fully driven by slivers.

Turns out when I added tests, I broke the actual underlying functionality.

This reverts commit ea21d0c5 which
didn't resolve the pagination control overflow issue. Commit
7425940d replaces this as an alternate
workaround. Once flutter/flutter#7980 is resolved, we should revert
7425940d and scroll instead.

Once engine commit d49a6b110bced49fa318b0dd45bf409218df9ee5 rolls into
Flutter rolls in, we get correct font metrics for the Ahem font, used in
headless sky_shell test runs. Ahem has much wider glyphs than the system
font, which causes the PaginatedDataTable bottom bar to be much wider
and overflow the previous and next controls offscreen.

This commit reduces the number of rows such that the prev/next controls
are still just barely onscreen.

Fixes #7119

The Ahem font has a much wider average text width than most fonts.

Now that ensureVisible works, we can use ListView instead of Block in
this demo.

* improve the logger ui a bit for elapsed times

* invert param

* update daemon.dart

Also, switch Stepper over to using sliver-based scrolling.

Differentiate between the not-installed and the out-of-date scenario.

Call `pub upgrade` instead of manually deleting `pubspec.lock` and then calling `pub get`. `pub upgrade` ignores the `pubspec.lock`, but is otherwise identically to 'pub get' (https://www.dartlang.org/tools/pub/cmd/pub-upgrade).

Add a user friendly error message when no development team is selected for physical deployment (#7879)

Bump to keep up w/ DDC fixes.

Support for thinning app frameworks to the target architecture was added
in 708909fc. This commit adds support
and error-checking for non-fat frameworks that are not of the target
architecture. In such cases, we now fail the build, and emit an error
message and the contents of lipo -info for the affected framework.

This patch improves PageView to the point where we can use it in the date
picker. Specifically, you now get onPageChanged notifications and you can
control which page is visible using a PageController.

There appears to be an issue with children before the center widget.
I've filled a bug about that issue and will follow up in a later patch.

We need to study these benchmark numbers more carefully. See #7937

* Support thinning iOS frameworks to supported architectures

When building against frameworks that are distributed as
multi-architecture fat binaries, we want to strip the frameworks we
distribute down to only the architectures specified in $ARCHS.

This patch adds:
* The ability to specify commands to xcode_backend.sh (if none is
  specified, run BuildApp for backward compatibility).
* A 'thin' command that invokes lipo to thin down the distributed as
  described above.

* Add framework thinning step to iOS build

Invokes xcode_backend.sh thin on the build application.

* Limit architectures to arm64 in Xcode template

Flutter does not yet support armv7 iOS devices. Limit the $ARCHS build
variable to arm64 until then.

* has all the cherry-picks fixing known issues merged.
