* Revert "Temporarily comment out this condition so the install runs on Travis"

This reverts commit 74db9366b4b1b094369388ef50fb26f3b7fd3104.

* Pin to nodejs v8.1

* Include stdout/stderr in failure messages

Sometimes some of these tests unexpectedly fail with a non-zero exit code. This ensures stdout/stderr is included in the test failure message when this happens so that we can track down the issue.

* Remove redundant info about exit code

* Remove unnecessary indenting

The [markers] make it fairly clear so this just makes the test code noisy.

Fixes #18995.

This logic is described in the test as looking for a scroll ending
very close to a new page, but in fact its behavior is more like
"very close to a page to the right": if we're not very, very close
to any page, it will pick the page to the left, not an old page.

There's no reason this should be left-right asymmetrical.
Instead, pick the nearest page.

In practice, the case where this makes a difference never arises when
the scroll runs undisturbed to completion; but when the user taps on
the page to hold or drag, the scroll will be interrupted before it
gets within tolerance of a particular page, and this case does arise.

This fixes a glitch that is hard to trigger without time dilation,
but is quite conspicuous with it:

 * Open a tab view with at least 4 tabs, e.g. the Buttons screen
   of the gallery (with "Animate Slowly" on.)
 * Starting at tab 0, tap tab 2.
 * When the animation is nearly complete, tap the page a couple
   of times, as if to drag it around to scroll.  Then let the
   page view settle ballistically toward page 2.
 * Before it finishes, tap tab 3.
 * Suddenly page 1 fills the view, replacing page 2, before we
   scroll from there to page 3.

With this fix, the animation in the last step moves smoothly from
where we are when it starts onward to page 3.

Also:
 * Export TextInputAction from `text_field.dart` to parallel `TextInputType`.

Before a severe log would be raised when timeout happens. Now that
testing connections requires potentially running into a timeout, this
will cause failures when there shouldn't be any.

* Support all keyboard actions. (#11344)

Fixes #18829

Otherwise on Windows these will fail as an unsupported platform when things try to read defaultTargetPlatform in flutter apps.

This fixes #18727 

Goldens for flutter/flutter#18729

Our first step towards https://github.com/flutter/flutter/issues/18727

This test was designed to ensure flutter_tester keeps running (previously it would quit immediately). However it's turned out ot be rather flaky and we have new tests on the way that supersede this by actually testing real things (debug stepping, reloading, expression evaluation).

* Remove the 'app' domain from flutter daemon

By default the daemon won't register the "app" domain, you need to opt-in (which the 'run' command does, as well as the tests for the app functionality).

Fixes #6658.

* Tweak text

* Put restart/callServiceExtension/stop back into daemon mode

* Add a comment about removing discoverApps

* Fix typo

* Add emulator.create to Daemon API

* Swap order of daemon changelog entries

Add iOS module template

This will enable integration of flutter-views into existing iOS project.

See https://github.com/flutter/flutter/issues/13379#issuecomment-400984667.

This reverts commit 8be198d8 that broke the build.
