In widget tests after upgrading to Flutter 3.10.1, loading an asset results in Unable to load asset: "AssetManifest.smcbin" #127297
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
Not entirely sure what I did that caused this, and thus how to reproduce it. What I can for sure is,
- I upgraded to Flutter 3.10.1
- I have an assets directory in the root of my project
- The assets directory is connected to the app via my pubspec.yaml file like so:
assets:
- assets/
- Running the app and navigating to the screen that uses these assets (images) works correctly
- Running Widget tests which navigate to screen that use these assets fail.
Expected results
Tests should pass.
Actual results
Tests fail with error:
