Issues with video attachments on web

[Ayush-gupta-josh]

Which packages are you using?

stream_chat_flutter

On what platforms did you experience the issue?

Web

What version are you using?

5.0.1

What happened?

There are two scenarios where video attachment breaks.

1. When we select any video -

   • When we select any video of size within the size limit then it breaks due to Unexpected null value.

   • In my opinion, this code is causing an error because you have mentioned that there will be no URL in case of web and here you are making it a mandatory value.

   • Screen breaks with this error

2. When we select a large video -

   • When we select a large video then there is no error on the screen instead it shows an Unexpected null value error in the console.
