Stacktrace link and Codecov won't be shown if only System frames for Flutter AOT apps

### Environment

SaaS (https://sentry.io/)

### Steps to Reproduce

Hi, I tried to set up Flutter AOT (Android/iOS) and the GitHub/Codecov integration but it's not working.

The frames are marked as “System” here so it won’t show the stacktrace link and neither will it try fetching codecov data .

The problem is that AOT-compiled apps can't detect the `inApp` on the SDK side since its all minified, leading all to system frames most likely.

Maybe the stack trace link and codecov data should be shown even if its system apps but have enough source code context.

### Expected Result

Stacktrace link and codecov data will be shown

### Actual Result

Stacktrace link and codecov data won't be shown
