Performance Optimization Issue for Default FlutterFlow App

Troubleshooting

I am currently learning FlutterFlow to develop apps and am exploring its features to determine if it meets my requirements. While I’m working on the free plan for now.

Project URL: https://app.flutterflow.io/project/test-5golyi?tab=uiBuilder&page=HomePage
Publihsed URL: https://test-5golyi.flutterflow.app/

Issue:

  1. The app exhibits a TTFB of 7.724 seconds and overall slow load times.

  2. This issue persists despite the page only containing the default settings (Page Title + App Bar) with no additional elements or functionality added.


Details from Request Logs:

1. main.dart.js: ~1MB, taking ~1.7 seconds to download.

2. Fonts and other assets (like fa-solid-900.ttf) add additional delay.

3. The app shows a 404 error for manifest.json, which might contribute to the delay.


Performance Metrics:

Initial page load is slow despite running in a production-like environment.

Tested from multiple devices and networks, with consistent results.

Expected Behavior:

For a default FlutterFlow page with minimal setup:

- TTFB should ideally be under 1 second.

- The total load time should be no more than 2-3 seconds.

Request- Please assist with:

- Identifying why the app is experiencing high load times even without additional functionality.

- Recommendations or optimizations for reducing load times and improving performance.

Let me know if you need any additional information or access to the project.

What have you tried so far?
