As of Flutter 3.27.4, the flutter-engine github repository is archived, and the flutter-engine source code now resides at https://github.com/flutter/flutter/. Because of the above, the following changes must occure: - Paths are now prefixed with engine/src. - The "name" field in the dot-gclient file is now "./", and the gen-tarball script: - Makes the dl-tmp/src dir - Copies the dot-gclient file to the dl-tmp/src dir - Runs gclient.py inside of the dl-tmp/src dir Without these changes, gclient creates two directores: dl-tmp/src/flutter and dl-tmp/src/engine, and cloning fails with the following error: ``` python3: can't open file 'dl-tmp/src/engine/src/flutter/tools/pub_get_offline.py': [Errno 2] No such file or directory ``` because the file resides at src/flutter/engine/src/flutter/tools. Changing the name from src/flutter to ./ and running gclient.py directly in the src directory creates a proper directory structure suitable for compiling. Of course, this also means there is a new pushd in the gen_tarball method to move to ${SCRATCH_DIR} to ensure the tarball is generated outside of the source directory. Tested with run-tests tests.package.test_flutter.TestFlutter.test_run. The license file has changed, but it's still BSD-3-Clause.
