https://github.com/flutter/engine/pull/43974 added a license file to the Dart SDK's ZIP archive. As a result, extracting the Dart SDK now needs to overwrite the cache's `LICENSE.dart_sdk_archive.md` file. This is a short-term solution that will be cherry-picked for the next [3.14 beta release](https://github.com/flutter/flutter/issues/132267). Addresses https://github.com/flutter/flutter/issues/132592. The long-term solution is tracked by https://github.com/flutter/flutter/issues/132702
Flutter SDK dependency versions
The files in this directory specifies pinned versions of various dependencies of the flutter SDK.
The bin/internal/engine.version file controls which version of the
Flutter engine to use. The file contains the commit hash of a commit
in the https://github.com/flutter/engine repository. That hash must
have successfully been compiled on
https://build.chromium.org/p/client.flutter/ and had its artifacts
(the binaries that run on Android and iOS, the compiler, etc)
successfully uploaded to Google Cloud Storage.
The /bin/internal/engine.merge_method file controls how we merge a
pull request created by the engine auto-roller. If it's squash,
there's only one commit for a pull request no matter how many engine
commits there are inside that pull request. If it's rebase, the
number of commits in the framework is equal to the number of engine
commits in the pull request. The latter method makes it easier to
detect regressions but costs more test resources.
The bin/internal/flutter_packages.version file specifies the version
of the flutter/packages repository to be used for testing. The
flutter/packages repository isn't an upstream dependency of
flutter/flutter; it is only used as part of the test suite for
verification, and the pinned version here makes sure that tests are
deterministic at each flutter/flutter commit.
