* reduce iterations to avoid test timing out

This reverts commit 1c021506.

The pre-commit tests never actually ran, so it looked green when it wasn't. This breaks 16 tests that depend on the argument existing, even though it isn't actually used.

This command line argument has already been removed in the main
Dart repository, so building flutter with the latest dart fails.

* Fix for nan pressure values and values outside min and max pressure ranges

* media query check

Update README.md to remove 404 link on Posse image

* Added sample to AnimatedWidget

* Updated AnimatedWidget example to use listenable from parent

* removed unused dep

* remove unused impport

* Fix incorrect condition

* Add outer try block for obtainKey errors. Add docs.

* change to // from ///, and do specific error handling

* Add return statement after error

* Add test

Revert "Add support for binary compression of dynamic patches by the flutter tool. (#27754)" (#28031)

This reverts commit b47da6c2.

* Discover port over mDNS 

* Update BUILD.gn for tools

Because we now have 2 separate GPU and UI threads.

* Refactor for iOS.

* For android_xxx_unopt_arm64&ios_xxx_unopt_arm, remove the _arm64/_arm suffix.
dart generated in host_xxx_unopt/host_xxx has an arch of x86_64 which supports arm64/arm.

* Remove suffixes for various archs.

Disable prefer_collection_literals in the analyzer until we can update to using set literals (#28024)

* Fixes Cupertino switch vibration

* Added sample code for a simple Icon, ref: #21136

* Removed duplicate line.

* Fixed incoreect parameter.

* Update icon.dart

Removed empty prose and added better context for sample code. Changed sample code for better visibility in execution of default app themes.

* Alas, Trailing space.

Nixed trailing space in comments.

Fixes https://github.com/flutter/flutter/issues/25025

Re-applies #27409 by reverting #27919

The analyzer issue (dart-lang/sdk#35940) has been temporarily
worked around by virtue of #27929

This fixes the offline Dash/Zeal docs generation to use the newly added dartdoc markers for different entity types to make it more exact when finding entity names.

Bumped Dartdoc to the next release.
