There are more places we can use this annotation, but this patch just gets us
started.

Generates an android.iml file and a package-level library for flutter.jar.

Does not set up an Android SDK in IDEA; this isn't possible with a
template-based approach. But IDEA shows a clear warning, so the
user can fix this by setting the SDK.

(When creating a Flutter project from within IDEA, we can fix this up
afterwards in the plugin.)

Fixes https://github.com/flutter/flutter/issues/9258

* update the font used for docs.flutter.io

* update to use the flutter primary color

* update the header background color

Brings us inline with the latest internal push.

* Scaffold appBar is-a PreferredSizeWidget, etc

* Updated

* Updated per review feedback

Tests that updates to selection base/offset editing state is updated on
controller updates.

Tests TextEditingValue.clear() clears text.

I can't figure out if this is genius or a giant hack.

This lets you use DefaultTextStyle.merge and IconTheme.merge without
specifying a BuildContext. It automatically merges in at the
appropriate place in the tree using a Builder widget.

In particular, if stdout.supportsAnsiEscapes is false, don't output ANSI.

Also, output stdout/stderr of tests that are normally silenced, if they fail.

Also, update the output to be more convenient when debugging.

Also, expand some abbreviations.

Remove intermediate animation listener

* Manually fix every use of Point.x and Point.y

Some of these were moved to dx/dy, but not all.

* Manually convert uses of the old gradient API

* Remove old reference to Point.

* Mechanical changes

I applied the following at the root of the Flutter repository:

git ls-files -z | xargs -0 sed -i 's/\bPoint[.]origin\b/Offset.zero/g'
git ls-files -z | xargs -0 sed -i 's/\bPoint[.]lerp\b/Offset.lerp/g'
git ls-files -z | xargs -0 sed -i 's/\bnew Point\b/new Offset/g'
git ls-files -z | xargs -0 sed -i 's/\bconst Point\b/const Offset/g'
git ls-files -z | xargs -0 sed -i 's/\bstatic Point /static Offset /g'
git ls-files -z | xargs -0 sed -i 's/\bfinal Point /final Offset /g'
git ls-files -z | xargs -0 sed -i 's/^\( *\)Point /\1Offset /g'
git ls-files -z | xargs -0 sed -i 's/ui[.]Point\b/ui.Offset/g'
git ls-files -z | xargs -0 sed -i 's/(Point\b/(Offset/g'
git ls-files -z | xargs -0 sed -i 's/\([[{,]\) Point\b/\1 Offset/g'
git ls-files -z | xargs -0 sed -i 's/@required Point\b/@required Offset/g'
git ls-files -z | xargs -0 sed -i 's/<Point>/<Offset>/g'
git ls-files -z | xargs -0 sed -i 's/[.]toOffset()//g'
git ls-files -z | xargs -0 sed -i 's/[.]toPoint()//g'
git ls-files -z | xargs -0 sed -i 's/\bshow Point, /show /g'
git ls-files -z | xargs -0 sed -i 's/\bshow Point;/show Offset;/g'

* Mechanical changes - dartdocs

I applied the following at the root of the Flutter repository:

git ls-files -z | xargs -0 sed -i 's/\ba \[Point\]/an [Offset]/g'
git ls-files -z | xargs -0 sed -i 's/\[Point\]/[Offset]/g'

* Further improvements and a test

* Fix minor errors from rebasing...

* Roll engine

* Fix tests to use Ahem, and helpful changes around that

- Fix fonts that had metric-specific behaviours.

- LiveTestWidgetsFlutterBinding.allowAllFrames has been renamed
  to LiveTestWidgetsFlutterBinding.framePolicy.

- LiveTestWidgetsFlutterBinding now defaults to using a frame policy
  that pumps slightly more frames, to animate the pointer crosshairs.

- Added "flutter run --use-test-fonts" to enable Ahem on devices.

- Changed how idle() works to be more effective in live mode.

- Display the test name in live mode (unless ahem fonts are enabled).

- Added a toString to TextSelectionPoint.

- Style nit fixes.

* Roll engine to get Ahem changes.

* Update tests for dartdoc changes.

* Fix flutter_tools tests

Fixes https://github.com/flutter/flutter/issues/7715

This reverts commit ff23a1eb.

Our iOS lab hardware is back to normal.

Rename State.config to State.widget
Rename State.didUpdateConfig to State.didUpdateWidget
Renamed all State subclasses' local variables named config to something else

* do not warn about out-of-date Flutter installation too often

* style fix

Added a PluginRegistry to the new project template. The registry files will be automatically updated at build time to register the native plugins.

Fixes #7814.

* Wiring fullscreen dialog

* Make fullscreen dialog use the new API. Add tests

* Review notes

* Move field back up

* final

Came across "can ve" while experimenting with Forms using VSCode and Dart Code. Glanced over the rest of the docs for typos while I was at it.

Also, add a specific message for BuildContext.size for RenderSlivers.
