Image not loading running in debug mode

## 🐛 Bug Report

The images are not loading when running in debug mode.
I tested in a new project got the same result.
Here's the project: https://github.com/RafaelR7/cached_network_image_test

### Expected behavior

### Reproduction steps

### Configuration
my flutter doctor:
[✓] Flutter (Channel stable, 2.0.4, on macOS 11.2.3 20D91 darwin-x64, locale en-BR)
[✓] Android toolchain - develop for Android devices (Android SDK version 29.0.2)
[!] Xcode - develop for iOS and macOS
! CocoaPods 1.8.4 out of date (1.10.0 is recommended).
CocoaPods is used to retrieve the iOS and macOS platform side's plugin code that responds to your plugin usage on the Dart side.
Without CocoaPods, plugins will not work on iOS or macOS.
