./gradlew assembleRelease -PenableComposeCompilerMetrics=true -PenableComposeCompilerReports=true
```
The reports files will be added to build/compose-reports in each module. The metrics files will be
added to build/compose-metrics in each module.
The reports files will be added to [build/compose-reports](build/compose-reports). The metrics files will also be
added to [build/compose-metrics](build/compose-metrics).
