* Widget Inspector support for tracking Widget creation locations.

* Add arguments to dartdoc.dart for Dartdoc's grinder and travis

* Fix bug in filter

Fixes https://github.com/flutter/flutter/issues/14393

For example, so that the gallery can override the media query globally.

* work around const lints

* update nonconst doc

* bump the dart sdk version to 2.0.0-dev.17.0

* 2.0.0-dev.20.0

* 2.0.0-dev.19.0

* Flatten change out from lots of merges and temporary hacks for #7224

* Expand fakes to cover cases where doctor passes

* -v != --verbose

* Cosmetic touchups

* delint

* Clean up summary line, add a switch for review comments

* Review comments

* nit

* review comment

* review comments

* Populate AnsiTerminal in context for daemon launches

* Strip out AnsiTerminal additions to context since they are no longer needed

Using a void list literal in this case is valid and correct, and will be
required for dart 2.

Note: void can be inferred here, but followed the lints to write it
explicitly even though that's arguably a bit weird in this case and less
backwards compatible.

Note: also fixes a bug wherein bottom media padding was applied even in the
presence of persistent footer buttons.

The material spec states that the keyboard should be positioned on top
of any bottom navigation bar or persistent footer buttons widget(s).

We no longer inset the bottom of bottom navigation bars / persistent
footer buttons by the bottom viewInset.

Body content bottom (and the bottom of bottom sheets) is now determined
by the greater of:
  1. bottom view inset (the keyboard height)
  2. bottom elements (nav bar, footer buttons)
relative to the window max-Y.

Add meta tag @optionalTypeArgs to the mixin classes where we don't expect a generic type to be specified at the points where the mixin is applied. This suppresses the analyzer warnings.

0672055a changed the Material widget to
always use Paths for representing the outline.
These paths are later used for clipping and drawing a shadow.
This changed introduced a performance regression, see:
https://github.com/flutter/flutter/issues/14403

We did not expect a path that is a rounded rectangle to be less
performant than a rounded rectangle, as Skia should be able to tell the
path is just a rounded rectangle.
Until we find a solution for this regression, we keep using RRect when
we can represent the shape with it.

In a scaffold, snackbars are positioned above the BottomNavigationBar
and/or PersistentBottomButtons, if present. In such cases, they should
not apply bottom media padding to their widget sub-tree.

With a little refactor and unification of how availability of copy/cut/paste is determined across platforms.

that was changed between the generation of the package file and the
initial upload).

This triggered an analysis failure only on the devicelab.

For backward compatibility we keep supporting specifying the shape as a
combination of MaterialType and borderRadius, and we just use that as a
default when shapeBorder is null.

To cleanup the implementation if shapeBorder was not specified we just
translate the specified shape to a shapeBorder internally.
I benchmarked paint, layout and hit testing, with the specialized shape
clippers vs. the equivalent path clippers and did not see any
significant performance difference.

For testing, I extended the clippers/physicalShape matchers to match either the
specialized shape or the equivalent shape.

This updates the CupertinoAlertDialog to respect text scale factor more properly. Before this, it would scale, but would clip the action buttons at large scales, and would draw in the safe area. It also didn't match the iOS alert because the content didn't scroll. Now it does those properly.

I didn't address the fact that buttons should lay out properly (Issue #14345), but that's probably pretty low priority.
