Duplicate of #1429.

Hey @duc-ios, any particular reason you are using two MaterialApp ?

[duc-ios]

@xsahil03x I have a big main app with multiple modules which are also flutter projects from different developers. StreamChat is just a module in that app.

[xsahil03x]

I am not able to reproduce the issue with the code sample you provided, can you also share the structure you have at your end?

[duc-ios]

@xsahil03x please check the attached screenshot for the modification I made.

App structure:
Main App

• routes:
  • Chat App
  • Support App
  • Feed App
  • ...

Each route is a sub flutter project.
