* Fixes Android keyboard bug

This reverts commit d8db70af.

* move flutter_assets to App.framework

* remove flutter_assets references from all pbxproj files checked in

Newer NDKs switched to clang which by default uses system linker, instead
we need to force it to use appropriate toolchain linker by passing
-fuse-ld= command line flag.

Fixes #23458

This reverts commit 9880baa3.

Reason for revert: broke `--local-engine` command line option.

Generally, we should always use default-less switches for
platform-specific behaviour so we're forced to make a conscious decision
on each instance of such behaviour any time we add support for a new
platform.

* Add labelStyle + unselectedLabelStyle to TabBarTheme

The lerp method for IconThemeData was not doing anything to prevent exceptions when null arguments are used. This change fixes that and adds a test for it.

* Include caret gaps in position calculation to avoid descender cutoff

* Calculate caret offset instead of exposing it

* Test that textfields scroll vertically by full line height

* Only add offset to end of caret to avoid going above 0.0

* Fix and test horizontal vs. vertical scrolling

* CR: docs and top caret offset logic

* Take max instead of assuming caretRect.top is always a full line down

* Always subtract caretOffset from caretTop since caretRect.top can be negative

Generally, we should always use default-less switches for
platform-specific behaviour so we're forced to make a conscious decision

platform.

I fixed this TODO a while ago during my a11y work.

Previously, a disabled floating action button always had zero
elevation, which looks dumb.

This also fixes the issue whereby highlightElevation was not honoured
on floating action buttons.

This also fixes an issue I found during testing whereby setState was
being called during build when onHighlightChanged fired due to
onPressed becoming null while a gesture is ongoing (which triggers an
onTapCancel synchronously during build).

Adds asserts on required constructor parameters to a transition widgets.
This improves debuggability for those who aren't developing with live
analysis. e.g. when `turns` is not specified in a RotationTransition
constructor:

  package:flutter/src/widgets/transitions.dart: Failed assertion: line 43 pos 15: 'listenable != null': is not true.

becomes:

  package:flutter/src/widgets/transitions.dart': Failed assertion: line 259 pos 15: 'turns != null': is not true.

copySharedFlutterAssetsTask copies the `flutter_shared` folder assets to android's `src/main` folder of Flutter project, so that folder is bundled on the generated AAR

This was added to make sure we don't crash before the engine is rolled
with the system channel API addition and is no longer needed.

* remove ignore_for_file lints

* update comments

* remove example

* Fix `flutter test`e xpression eval tests

We weren't passing `beforeStart` through so the breakpoints were never being set, which means the evaluations were happening while the code was running.

* Ensure we wait for breakpoints before trying to evaluate

Fixes https://github.com/flutter/flutter/issues/25703

* Allow a widget to be specified for the textfield count, and allow no count at all

* InputDecoration has counter widget, TextField has buildCounter function

* InputDecorator tests expect counter to be widget again and include
buildCounter

* counter widget example that might actually fit

* Clarify accessiblity concerns in docs

* Include isFocused param for accessibility

* Fix analyze error

* Improve docs per code review

* Rearrange getEffectiveDecoration a bit for clarity
