Flutter SonarQube: "The main branch has no lines of code."

Question

Trying to run static code analyzer sonarqube for my Flutter project.

Steps currently followed,

1. Downloaded Sonarqube community version.
2. Downloaded the SonarQube flutter plugin
3. Moved the Jar file to the extension/plugins folder, verified it is in the installed plugin in the Sonarqube dashboard.
4. Downloaded sonar-scanner.
5. Added the sonar-project.propertise file in the project, refer the code in the below section.
6. Ran sonar-scanner, logs shows as execution is successful, attached in the below section.

When I go to the Sonarqube dashboard (at, http://localhost:9000), it show an warning saying, The main branch has no lines of code., Not sure what is incorrect here, I tried creating a new flutter project from scratch which doesn't have any VCS, but still same error, stuck on this for quite long.

Logs:
