Previously, the usage analytics would generate a write to the user's
HOME directory during the Fuchsia build. We're tightening down the
environment in which we run the Fuchsia build, and these writes are now
more obvious.

This patch removes the usage analytics during the Fuchsia build,
avoiding the write to the user's HOME directory.

Archive builds for upload to iTunes Connect should always be built in
release mode, not doing so results in crash on startup.

* fix updrade script; upgrade to the latest package versions

* exclude special dependencies from transitive closure

* fix stack trace handling in flutter_test due to stack_trace change

* change type on _emptyStackTrace

Use a `package:` import when referencing source under test in test template.

This is the prefered style and plays nice w/ automated refactoring.

* Add a pageSnapping parameter to PageView

Setting the pageSnapping property allows extending the PageView scroll
behavior, such as custom scroll animations or custom scroll bars.

* Apply pageSnapping CR feedback

- Remove _kNonSnappingPhysics, use null instead.
- Minor code style fixes.
- It turns out that the forth state is Arkansas, not California.

This adds an optional character counter and maxLength parameter to the TextField, as described in the Material Design Spec.

The counter text and style in the input decorator may be specified, but will default to the "right thing" if not specified, where the "right thing" is a counter that looks like "3 / 10" (if there are three characters entered into a field where maxLength is set to 10).

To limit the number of characters entered, I created a LengthLimitingTextFormatter that will limit the number of characters (Unicode runes) in the input, which can be used independently. The formatter is applied after the other formatters supplied (if any). Even if there is no decorator, the text field will limit the number of characters input if maxLength is set.

If maxLengthEnforced is set to false (it defaults to true), then the max length will not be enforced. In that case, if the text exceeds the length, then the counter will turn red, and it will make the divider turn red.

Revert "Fixes InputDecorator to work with textScaleFactor, fixes Material Design differences. (#12595)" (#12678)

This reverts commit 67cf7918.

Reverting because this causes scuba regressions that I'd like to
address in another PR that is pending, but we'd like to roll Flutter.

* Revert "Construct the accessibility channel's events by SemanticsEvent. (#12638)"

It may (or may not) have caused a performance regression. Hard to say.

* Theme provides all TextStyle properties

* match field declaration order in the test

* Theme.of returns text style with inherit == false

* change TextStyle.inherit logic; docs

* add TextStyle.debugLabel

* address comments

* add debug labels to Typography text styles

This avoids some code duplication that existed before and will make
further modifications easier.
