  <p>When ı get this error the same message data is appending to the chat list and it gives crash then.</p>
  
  <p>I am trying to write chat application with react-native-gifted-chat and I expect more than 15.000 messages from user but my gifted-chat can not even handle like 1000 message. İt gives this error.</p>
  
  <p>I get data from mongodb via socket.</p>
  
  <p>Is there any way to render message data with really good performance ? 
  I researched a lot about it, PureComponent etc etc. nothing works :/</p>
