Navigation from RoleSelection opens blank white screen in Test Mode

Hello, I am building a FlutterFlow app called Flash Deals and I am experiencing a navigation problem in Test Mode.

The app starts correctly on SplashScreen and automatically navigates to RoleSelection. RoleSelection also displays correctly.

However, when I press the “Continue as User” button to navigate to another page, the destination becomes a completely blank white screen.

Initially I thought CustomerRegistration was the problem, but I tested the same navigation with several different destination pages, including MerchantLogin, CreateFlashDeal and a newly created test page. They all resulted in the same blank white screen.

The destination pages display normally inside the FlutterFlow Builder. The problem occurs when navigating to them in Test Mode.

I have tried:

• Removing and recreating the Navigate To action on the button.
• Navigating to different existing pages.
• Creating a new test page and navigating to it.
• Removing the RoleSelection On Page Load navigation action.
• Testing navigation from a newly added temporary button.
• Changing the app Entry Page temporarily for testing.
• Checking FlutterFlow Issues: there are 0 errors. The only warnings shown are Google Maps placeholder API-key warnings.
• Authentication is currently disabled.

SplashScreen → RoleSelection works correctly, but navigation from RoleSelection to another page results in the blank white screen.

I would appreciate any advice on what could be causing this or what I should check next.
