Google Fonts not loading since latest Flutter upgrade

[blistick]

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

Since the upgrade to Flutter 3.38.5 my default Google font, which is Poppins, is not loading. It appears that this is because the file AssetManifest.json is missing or empty. I believe that 3.38.5 Flutter does not include this file in projects, but the old version of google_fonts that's being used by FlutterFlow relies on the file for font loading.

Expected Behavior

I expect the default Google Fonts to load without error.

Steps to Reproduce

1. Create a new project
2. Choose Poppins as the default font
3. Create a widget that uses the font
4. Run the project in debug mode and monitor the console log

Reproducible from Blank

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

I am experiencing the same issue in the Test mode. I use the same font with different weights in all instances, but my app lost nearly all the fonts and is randomly displaying some weights inconsistently. While in the console, there are no font-related errors.

My app looks like this in the test mode:

When it is expected to look like this:

Hi!
I’m sorry you’re experiencing this issue. I tried to replicate it, but unfortunately I wasn’t able to reproduce the error. It’s possible that this was resolved in the latest update, as I can see you’re using version 5.2.1.

Please try updating FlutterFlow, or let me know if the issue has already been resolved in your project.

Best regards
