Hi is this in the sample app? can you give me more information?

[ChiragGajjar]

Yes, but I am not using MaterialApp, because I have my own custom navigation.

[imtoori]

yeah but you still need a StreamChat widget on top of your widget tree? did you add that?

[ChiragGajjar]

Yes, Check my code here

return StreamChat( client: client, streamChatThemeData: StreamChatThemeData.fromTheme(theme), child: ChannelListPage(client: client,), );

[imtoori]

The StreamChat widget should be on top of the navigator because it needs to be retrievable by other widgets in every route Can you try moving it above the navigator?

[ChiragGajjar]

Like this? This is working fine, it shows a nested view but I don't use this MaterialApp because i have my custom header.

return Scaffold( body: MaterialApp( builder: (context, child) => StreamChat( client: client, streamChatThemeData: StreamChatThemeData.fromTheme(theme), child: child, ), home: ChannelListPage(client: client,), ), );

[imtoori]

yes, but you told me you're not using the MaterialApp widget, right?

[ChiragGajjar]

Correct

[imtoori]

you need to put the StreamChat widget on top of your custom navigator

[ChiragGajjar]

This looks like this. so i want to navigate outside the navigator, i don't need the bottom bar and top bar.

[imtoori]

ok I'm sorry the snippet is wrong, I just noticed there's a scaffold as top widget.

That said

Yes, but I am not using MaterialApp, because I have my own custom navigation.

You should put the StreamChat widget above the navigator widget you're using

[ChiragGajjar]

I have tried this but, but user listing screen showing correctly but when i tap on the chat details screen its showing error like this

The following assertion was thrown building _BodyBuilder: You must have a StreamChatTheme widget at the top of your widget tree 'package:stream_chat_flutter/src/stream_chat_theme.dart': Failed assertion: line 25 pos 7: 'streamChatTheme != null'

[imtoori]

mmm can you show me where do you put the StreamChat widget? Sorry for the many questions, but I need more info

[ChiragGajjar]

@imtoori thanks a lot, I have not added StreamChat in chat details at the top. now it's working fine. Thanks.

[imtoori]

sounds good even if I would still put it above the navigator widget
