project-dir

When specified, the tool uses the path passed into this option as the directory of the root Flutter project.When null, the relative path to the present working directory is used.

[no-]required-resource-attributes

Requires all resource ids to contain a corresponding resource attribute.By default, simple messages won’t require metadata, but it’s highly recommended as this provides context for the meaning of a message to readers.Resource attributes are still required for plural messages.

[no-]nullable-getter

Specifies whether the localizations class getter is nullable.By default, this value is true so that Localizations.of(context) returns a nullable value for backwards compatibility. If this value is false, then a null check is performed on the returned value of Localizations.of(context), removing the need for null checking in user code.

[no-]format

When specified, the dart format command is run after generating the localization files.
