I modified TextAlign docs because the descriptions of TextAlign.center and Center Widget are so similar that they cause confusion.

Fixes https://github.com/flutter/flutter/issues/5805

Integration tests must only go through the real file system/process manager/platform. The global indirection makes this code harder to understand than if it directly referred to the concrete instances that are being used.

Update the integration shard to use a const instance of a LocalFIleSystem, LocalProcessManager, and LocalPlatform. Remove global usage and apply testWithoutContext.

Currently the framework uses fairly large "hit slop" values to disambiguate taps from drags/pans. This makes sense on touch devices where the interaction is not very precise, on mice however it can feel as if the UI is lagging. This is immediately noticeable on our infra dashboard, where it takes almost half of a grid square of drag before the actual drag kicks in.

One potential solution is to always use smaller constants depending on whether the interaction is mouse or touch based. The only reasonable choice is to use the pointer device kind and not target platform - same platform can have different input sources. This requires exposing the pointer device kind in a few new places in several of the gesture detectors, and using the enum to compute the correct hit slop from an expanded set of constants.

This almost works, however there are a few places (notably ListViews) which uses the touch hit slop as a default value in scroll physics. It does not seem like it will be easy to disambiguate a user provided scroll physics constant from the default and/or adjust it somehow - this might require significant changes to scroll physics which I have left out of this PR.

This PR does not adjust:

kTouchSlop used in scroll_physics.dart's minFlingDistance
kTouchSlop used in PrimaryPointerGestureRecognizer/LongPressGestureRecognizer

Allow Developers to enable Accessibility testing on WebFlutterDriver and get the underlying webDriver (#65051)

This allows us to rationalize the nullability of some of our APIs.
Prior to this we'd end up in a situation where Container assumed that
getClipPath would be non-null but Decoration was ok with return null.

In order to share logic across build/archive/ipa commands, move the project parsing/validation into a different function. #64683

Fix run release/profile modes generating a full service worker.

Currently flutter run -d web creates a server with the x-frame-options: SAMEORIGIN added by default (shelf add it's by default). This doesn't allow you to use it inside a frame.

I am trying to build an embedded simulator in vscode and it requires using an iframe.

With this PR I remove the header for debug and profile mode.

Previously, the CPU/GPU measurement using gauge happened after the
driver test is done. Now, the measurement happens within the driver
test. So we need to properly increase the delay and duration to get a
comparable reading as the old gauge measurements.

Those 2 tests have been green for the last 10 runs

The flutter tool is currently unable to detect missing permissions in gradle/gradle.bat that would cause a gradle build to fail via process exception. Rather than crashing and exiting, we can display the exception as an error message and tool exit.

While linux/macOS are able to add the +x bit, this is not possible on windows with our current file system/OS API. These crashes represent a substantial amount of crash reporting, but are otherwise not actionable on our end.

More work to prevent current #2 crash issue on stable. If adb is not located do not list/create android devices.
