annotations property
Adds information from your analysis to specific lines of code. Annotations are visible on GitHub in the Checks and Files changed tab of the pull request. The Checks API limits the number of annotations to a maximum of 50 per API request. To create more than 50 annotations, you have to make multiple requests to the Update a check run endpoint. Each time you update the check run, annotations are appended to the list of annotations that already exist for the check run.
Implementation
final List<CheckRunAnnotation>? annotations;
