Page title does not change to local language for new email sign in

[nachiketkhasbag]

Page title stays "Connexion" for new email sign ups.
Should change to "FFULocalizations.of(context).signInLabel"

sign_up_view.dart:

Possible problematic code:
appBar: new AppBar(
title: new Text("Connexion"),
elevation: 4.0,
),

Expected:
Page title should adapt to supported Locale
