Flutter - Unable to load asset on first load only

问题

I load an image on my flutter app like this:

Image.asset(imageFilePath, fit: BoxFit.cover)

When I run the app on the emulator on the first run I get the following exception:

I/flutter ( 7194): ══╡ EXCEPTION CAUGHT BY IMAGE RESOURCE SERVICE ╞════════════════════════════════════════════════════ I/flutter ( 7194): The following assertion was thrown resolving an image codec: I/flutter ( 7194): Unable to load asset: /data/user/0/com.example.myapp/app_flutter/888cba5135c38f7d.jpg ...

The image path is correct, and the file exists.

If I re-run the application (click the button), the application loads without the exception and the image appears just fine.

What could be the issue?

Note:

• flutter doctor states everything's fine
• flutter version: v1.9.1+hotfix.2

You're saying that your file isn't asset, then use another Image constructor:

final img = Image.file(File(imageFilePath));
