internal.gherkin.ast* package is missing in cucumber-java@7.4.0 version

We were using this package --  import io.cucumber.core.internal.gherkin.ast* in our internal report dependency with cucumber-java@5.5.0 version but with cucumber-java@7.4.0 version this package is completely removed. We cant find equivalent function to be used with 7.4.0 version. Checked documentation and couldnt find helpful for my case. Please help me with equivalent function to be used. 

Many Thanks!
