Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

Random pages are not displaying at all, despite seemingly no issues, and they appear after I publish the page.

Expected Behavior

View all pages and elements within test mode.

Steps to Reproduce

1. Have some random pages (no clue what exactly is affecting it, but it's definitely on my more complex pages. Sometimes with multi DB calls or a bunch of conditionals.)
2. Run in test mode. - see there is no display
3. Publish. - see there is content being displayed

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Additional Information

I was getting really frustrated because I couldn't figure out what was wrong. Despite everything looking right, the test mode wasn't displaying anything. If I want to send this link out for beta testing this week, I can't make any changes to the published mode without potential disruptions. Publishing is the only way right now I can test what the real app looks like and that takes a significant time to do each change also.

I brought the code to cursor, and it said that the Test Mode uses Flutter/Dart version 1.19.1 while my app is locked in with version 1.19.0. I wasn't able to find how to auto- or manually update these since the dependency page says, "These are Dart packages that the code generated by FlutterFlow depends on. You cannot edit or remove these."

It also caused me to break apart some of my more complex pages and components because I couldn't figure out what was wrong. Now this will be an issue later on to consolidate with conditionals, have increased potential mismatches, and increased maintenance overhead.
