From support:

Currently, FlutterFlow does not support granular permissions to specifically exclude videos while only allowing image selection through the built-in Pick Files, Camera Upload, or similar widgets. Here's why: these widgets often request broader access (e.g., READ_MEDIA_IMAGES), and video permissions may come bundled as part of Android's permission groups.

But worry not! Here's how you can address this within FlutterFlow:

Steps to Limit Permissions for Profile Image Uploads:

Custom Code with File Pickers:

For more control, you can use custom code through Flutter packages like file_picker. This package allows you to specify file types precisely, such as only .jpg, .png, etc., for image selection.
Leverage Google Play Console Policy Updates:

If you’re publishing your app and are concerned about permissions compliance, ensure to include a privacy policy detailing how your app uses photo and video permissions. Clearly state your app's intention (e.g., photo uploads only for profile pictures). It will help mitigate rejections from the Play Store.
Testing Permissions:

Before submitting your app to Google Play, thoroughly test on multiple devices to verify no unexpected permissions (like videos) are requested during usage.
Feedback to FlutterFlow Roadmap:

This feature—granular permissions—might not have been addressed yet, judging by your shared GitHub link and community posts. You can submit this feature request directly to FlutterFlow's Roadmap if you'd like to bump its priority further: FlutterFlow Feedback.

Workarounds for Now:

Communicate Usage to Users:
Add a brief text or tooltip in your app clarifying why permissions are required (e.g., \"For profile picture only—video will not be accessed\").
Limit Access Using File Extensions: Filters such as .jpg or .png in the custom code would inherently prevent videos from being selected.

Please note that configuring permissions this way ensures Google recognizes the app's limited context, reducing the chances of any rejections.
