Hi, I tried to build a project from scratch using iOS and (un)fortunately I don't have any problem.
Can you try to run flutter clean and try to rebuild the project?

@brizaldi can you also include the entire stack trace error as well as information about the flutter version you are using?

@brizaldi did you do everything written here in the readme? https://github.com/GetStream/stream-chat-flutter#ios

[brizaldi]

@imtoori yeah, but still got crash whenever i try to open the app, btw i test it on iOS Simulator though

[imtoori]

So, I googled your stacktrace and I reach this issue on the Flutter repository, but unfortunately it's still waiting for customer response

A question: have you modified the iOS project in any way?

[brizaldi]

i only change deployment target to 9.0 and add google gms api key in AppDelegate.swift

this is from simulator system.log

i dont know if this gonna help but i got an error in GeneratedPluginRegistrant.m saying Module 'file_picker' not found

here's my GeneratedPluginRegistrant.m

I think something broke during flutter packages get. Sometimes it happens with Flutter

Can you try this?

• delete the file ios/Podfile
• run flutter clean
• retry to run the app

[brizaldi]

still got the same error

[brizaldi]

@imtoori @tbarbugli i think i've found the culprit, its because this plugin is incompatible with flutter_form_builder, when i remove flutter_form_builder from dependency, the error suddenly gone, maybe you guys can find out whats the problem, because my app depends a lot from that plugin

[tbarbugli]

@brizaldi thank you for the additional information; if possible would you mind sharing a dart file that reproduce the problem with the form builder and chat?

[brizaldi]

just create a new flutter project, and then add flutter_form_builder and stream_chat_flutter dependency

[imtoori]

@brizaldi can you retry now using the new version 0.1.12?

We were using the plugin keyboard_visibility while flutter_form_builder was using flutter_keyboard_visibility. The former is a fork of the latter and it seems better maintained so we'll stick to that.

[brizaldi]

it seems working fine now, thanks @imtoori, i'm closing this now
