This removes the extraneous whitespace printed when the flutter command is invoked, but didn't wait for a lock. It only is a problem when the carriage return isn't honored (as in IDE consoles).

Work towards #16723

This is only safe to land after #58131 lands in google3. Only build NOTICES in asset manfiest, and load either LICENSE or NOTICES from pubspec dependencies.

Prevent WhitelistingTextInputFormatter to return a empty string if the current value does not satisfy the formatter (#57264)

Error message when size has not been set in RenderBox's performLayout should be well versed (#58151)

PR #57749 included changes to the way the project interacts with the
build process (e.g., bundling the necessary library), so should have
incremented the template version to trigger the messaging to developers.

* Adds default cursor and/or mouseCursor property to a number of widgets.
* Adds `MaterialStateMouseCurrsor`.

Builds and bundles an 'app.so' containing AOT data, and downloads and packages the release/profile artifacts for those builds, rather than always using the debug artifacts.

BundleUtilities apparently doesn't do build-system-style timestamp
analysis when deciding what to copy, and instead just doesn't copy
things that are already present. This cleans that bundle directory on
each build, so that it includes the up-to-date library versions.

Since this is just copying from build artifacts, this is very fast; the
build steps themselves are not affected.

Fixes #58003

The .dart_tool directory can contain build assets, as well as the package_config.json file - the replacement for .packages. Remove it for the same reason we remove .packages

To make #57871 easier to land, add support for loading either LICENSES or NOTICES, preferring the later.
