A few rules of thumb will help you and us in finding the correct repository for the issue:

1. If you encounter an issue when using the HTML/JS API of a component or the component renders incorrectly, the problem is likely in the web component. The web component repositories are named like https://github.com/vaadin/vaadin-button
2. If you encounter an issue when using the Java API of a component, the problem is likely in the Flow integration of the web component. The Flow component integration repositories are named like https://github.com/vaadin/vaadin-button-flow
3. If you encounter an issue with Flow which does not seem to be related to a specific component, the problem is likely in Flow itself. The Flow repository is https://github.com/vaadin/flow
