Improve GlobalKey docs by mentioning a pitfall that some users had where the instantiated it in the build method.

it is possible for users that download the prebuilt SDKs to run the tool without unzip installed. Rather than crashing with an unclear argument error, exit the tool with a message on how to install that mirrors the message in the update_dart_sdk.sh script.

Also applied to zip for completeness

This is a continuation of https://github.com/flutter/flutter/pull/61366
after cl/333620714

See also https://flutter.dev/go/clip-behavior

The previously broken test should be fixed by
https://github.com/flutter/gallery/pull/331

Instead of always exiting the tool, provide a mechanism to turn off this behavior for non-critical functionality like configuration and analytics settings.

This reverts commit 2d9e5005.

In addition, this fixes broken Android tests of the original PR.

Check in linux and windows platform code now that they are stable, so that we could use in devicelab in the future. Removed the ICO from the windows example to avoid analysis check, and since it won't be important for benchmarking or UI tests

* Add back autovalidate property

* Add autovalidate property back (include tests)

* Fix typos

* One more test :)

* Divider with subheader example update

* fixed issues

* Addressed comments

* fixed issues

* apply upcoming lint cast_nullable_to_non_nullable

* make RenderObjectElement.renderObject non-nullable

This message is displayed if we do not find a pubspec.yaml

99% of the time this additional advice is going to have nothing to do with the actual error. Just remove it because it will cause more confusion than it could clear up

Crash reporting shows at least one instance of EACCES during an existsSync cache call. Add this to the list of error handling io methods. Did not add the async exists method since we lint against its usage.

[Icons][iOS] Pointing to version of material icon font that includes more metadata in the xml. (#66684)

Simple docs fix for characters.

Teach the flutter tool how to find android output files if the flavor contains uppercase letters (#66687)

This changes the name of the generated output files on android in case a flavor with uppercase letters is used.
Previously, the lowercased flavor name would be used for the apk/aab file. Now, the flavor name is used as-is.

The lack of current directory wrapping was letting some of the already handled errors through

Fixes #66675

This PR also enables firebase tests on presubmit and removes code that
won't be used anymore from test runner.

Bug:
  https://github.com/flutter/infra/pull/225

The Dart SDK now requires non-null enum values if the enum is used in an
exhaustive switch statement on a non-nullable type.
