Roll dependendencies This rolls depdendencies to latest using flutter update-packages --force-upgrade This change includes three code changes: * Removes charcode from the dependencies allowlist since it no longer appears in the transitive closure of dependencies of the flutter, flutter_test, flutter_driver, flutter_localizations, and integration_test packages. * Uses Resolver.create instead of the deprecated Resolver constructor. The default Resolver constructor has been deprecated in favour of the static Resolver.create() factory function, which unfortunately happens to be async. Propagated the async-ness up the chain. This change was partially reverted and the deprecation ignored in this patch until package:coverage can be rolled internally at Google. * Eliminates the use of the deprecated packagesPath parameter to HitMap.parseJson. This parameter was deprecated and replaced with packagePath in https://github.com/dart-lang/coverage/pull/370 which was part of the overall deprecation of the .packages file in Dart itself https://github.com/dart-lang/sdk/issues/48272. The overall goal being that end-user code shouldn't need to know about implementation details such as whether dependency information is stored in a .packages file or a package_info.json file, but rather use the package_config package to obtain the package metadata and perform other functions such as resolving its dependencies to filesystem paths. packagesPath was replaced by packagePath, which takes the path to the package directory itself. Internally, package:coverage then uses package_config to do the rest of the package/script URI resolution to filesystem paths. This change was partially reverted and the deprecation ignored in this patch until package:coverage can be rolled internally at Google. This is a pre-update prior to updating flutter_template_images in https://github.com/flutter/flutter/pull/103739 Issue: https://github.com/flutter/flutter/issues/103371 Issue: https://github.com/flutter/flutter/issues/103775 Issue: https://github.com/flutter/flutter/issues/103830 When re-applying the partially-reverted changes to code coverage, we'll need to patch host_entrypoint.dart internally to await the Future that we'll be returning rather than a non-async value.
Token Defaults Generator
Script that generates widget component theme data defaults based on the Material Token database. These tokens were extracted into a JSON file from an internal Google database.
Usage
Run this program from the root of the git repository:
dart dev/tools/gen_defaults/bin/gen_defaults.dart
Templates
There is a template file for every component that needs defaults from
the token database. These templates are implemented as subclasses of
TokenTemplate. This base class provides some utilities and a structure
for adding a new chunk of generated code to the bottom of a given file.
Templates need to override the generate method to provide the generated
code chunk as a string. The tokens are represented as a Map<String, dynamic>
that is loaded from data/material-tokens.json. Templates can look up
whatever properties are needed in this structure to provide the properties
needed for the component.
See lib/fab_template.dart for an example that generates defaults for the
Floating Action Button.
