How to send data from one webpart to another webpart using dynamic data in spfx

I have two webparts inside a project i am trying to send a value to another web part. I gone through the documents in microsoft sharepoint on dynamic data . But hardly i get anything.

One webpart will be filtering and another webpart will display the filtered results.I just wanted to know to pass the value so that filtering could occur in second webpart.

Any suggestions will be helpful
