$saveEnv of type string is incompatible with the type array expected by parameter $envs of Yiisoft\Composer\Config\Plugin::overloadEnvs().

It seems like $this->rootPackage can also be of type null; however, parameter $package of Yiisoft\Composer\Config\Plugin::addFiles() does only seem to accept Yiisoft\Composer\Config\Package, maybe add an additional type check?
