Getting error while run flutter app in iOS

Thanks @TusharPatel sir, but I'm getting same error on pod install? — rvndsngwn, Sep 06 '21 at 07:20
This worked for me: flutter clean, delete /iOS/Pods, delete /iOS/Podfile.lock, flutter build ios. — rvndsngwn, Sep 13 '21 at 02:01

It seems that is a sort of bug/incombatibility issue in Cocoapods v 1.11.0

To fix the issue, I followed these steps and it worked like a charm: https://stackoverflow.com/a/69076515/16881741

Briefly, follow these steps:

In your terminal, in ios folder type

gem list --local | grep cocoapods
Take note of what is the output of the previous command. It looks like that (please ignore the version near the various entry, this is my output and I already use the version 1.10.1):

cocoapods (1.10.1) cocoapods-core (1.10.1) cocoapods-deintegrate (1.0.5) cocoapods-downloader (1.5.1) cocoapods-plugins (1.0.0) cocoapods-search (1.0.1) cocoapods-trunk (1.6.0) cocoapods-try (1.2.0)

One by one, launch the command sudo gem uninstall X substituting the "X" with the name of the cocoapods component, without the version. At the end you should obtain this:

sudo gem uninstall cocoapods sudo gem uninstall cocoapods-core sudo gem uninstall cocoapods-deintegrate sudo gem uninstall cocoapods-downloader sudo gem uninstall cocoapods-plugins sudo gem uninstall cocoapods-search sudo gem uninstall cocoapods-trunk sudo gem uninstall cocoapods-try

Be sure to have included all the component listed in the point n.1 to avoid dirty status

Use the command sudo gem install cocoapods -v 1.10.1 To obtain the correct version.

All kudos to Esteban Lopez, the author of the answer I linked at the top.

This issues appeared in Cocoapods 1.11.0 and as many already noticed rolling back to 1.10.2 fixes the issue. But the original issue comes from wrong locale set in the terminal. It has to be a UTF-8-based locale.

The second answer in here solved the issue for me.

As stated, just run

export LC_ALL=en_US.UTF-8

in your terminal, and the error should go away. Consider adding this to your .zshrc file so that it happens automatically in every session.

This one solved my problem – Syed Saad Dec 06 '21 at 17:37 — Syed Saad, Dec 06 '21 at 17:37

NOTE: In all M1 machines, Android Studio & IntelliJ Idea terminal does not compile the pod install command yet. but all other terminals do it. I don't know the why. This is my observation. – rvndsngwn Mar 31 '22 at 05:51

Ran the same project on VCode and it worked successfully, guess the issue was with my Android Studio.
