This test is failing on mac_bot (but passing elsewhere) because flutter-tester is apparently quitting earlier than expected. Locally it fails with an even weirder error and almost all tests are failing with "Compilation failed" (this isn't happening on the builds, so something is bad on my MacBook). Marking as skip to fix build while investigating; there's no real impact of this test not running; it's testing a tool that its itself used for testing (and not currently in any way that should be affected by this failure).

Fixes https://github.com/flutter/flutter/issues/18200.

This should fix https://github.com/flutter/flutter/issues/18729

I'll add a gold test, and try to figure out how to remove the saveLayer without affecting the correctness later.

This should fix https://github.com/flutter/flutter/issues/18731 and I've added a unit test for it.

Introduced in d248725e, but has been red
since landing. Marking flaky rather than reverting since it's the only
failure.

The `flutter attach` test was failing because the Android device had
the app already installed.

Add `flutter attach` command.

This command allows Flutter to connect to applications that haven't been launched using `flutter run`.

Unbreaks flutter-build

* Revert changes to core SDK members that haven't been propagated to the g3 Dart SDK yet.

* Respond to comments.

* Remove retype

* Temporarily un-remove VMService.retype to unblock g3 roll

* Checkout back to master, we need fewer changes to reach compat with dev.61 than dev.60

This prevents the error:

`type 'List<dynamic>' is not a subtype of type 'List<Map<String, dynamic>>' `

The test added fails when dart_vm.dart is reverted to `master`, and succeeds in
its current state.  This issue was run into while connecting to the
Dart VM.

This fixes https://github.com/flutter/flutter/issues/18708

* Suppress stdout compile diagnostic when compile expressions.

This fixes https://github.com/flutter/flutter/issues/18574.

* Use equal sign for default values

* Revert "manual rollback of of 18530 (#18531)"

This reverts commit 3f79f8cb.

* Fix the offset calculation

* Add a unit test

* Bump mockito to 3.0.0-beta

* Few fixes

* fix test

* Bump image

* Fix

* New packages update

* With matcher pinned

* No more typed
