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.
Flutter Framework localizations
This package contains the localizations used by the Flutter framework itself.
See the localization README for more detailed information about the localizations themselves.
Adding a new string to localizations
If you (someone contributing to the Flutter framework) want to add a new
string to the MaterialLocalizations
, WidgetsLocalizations
or the
CupertinoLocalizations
objects (e.g. because you've added a new widget
and it has a tooltip), follow these steps (these instructions are for
MaterialLocalizations
, but apply equally to CupertinoLocalizations
and WidgetsLocalizations
, with appropriate name substitutions):
-
Add the new getter to the localizations class
MaterialLocalizations
, influtter_localizations/lib/src/material_localizations.dart
. -
Implement a default value in
DefaultMaterialLocalizations
influtter_localizations/lib/src/material_localizations.dart
-
Add a test to
test/material/localizations_test.dart
that verifies that this new value is implemented. -
Update the
flutter_localizations
package. To add a new string to theflutter_localizations
package, you must first add it to the English translations (lib/src/l10n/material_en.arb
), including a description.Then you need to add new entries for the string to all of the other language locale files by running:
dart dev/tools/localization/bin/gen_missing_localizations.dart
Which will copy the English strings into the other locales as placeholders until they can be translated.
Finally you need to re-generate lib/src/l10n/localizations.dart by running:
dart dev/tools/localization/bin/gen_localizations.dart --overwrite
There is a localization README file with further information in the
lib/src/l10n/
directory. -
If you are a Google employee, you should then also follow the instructions at
go/flutter-l10n
. If you're not, don't worry about it.
Updating an existing string
If you or someone contributing to the Flutter framework wants to modify an existing string in the MaterialLocalizations objects, follow these steps:
-
Modify the default value of the relevant getter(s) in
DefaultMaterialLocalizations
below. -
Update the
flutter_localizations
package. Modify the out-of-date English strings inlib/src/l10n/material_en.arb
.You also need to re-generate
lib/src/l10n/localizations.dart
by running:dart dev/tools/localization/bin/gen_localizations.dart --overwrite
This script may result in your updated getters being created in newer locales and set to the old value of the strings. This is to be expected. Leave them as they were generated, and they will be picked up for translation.
There is a localization README file with further information in the
lib/src/l10n/
directory. -
If you are a Google employee, you should then also follow the instructions at
go/flutter-l10n
. If you're not, don't worry about it.
