Flutter project failed to run on iOS when I install dart/flutter package to it

I just install android studio, Xcode, cocoapod and flutter/Dart SDK. When I create a new flutter project it run fine on both iOS and android. If I install a dart/flutter package to my project I got the error message below.

Below is the error message

Solution

  • The Solution to the Question above

    1. Open command terminal on your Mac PC.

    2. Navigate to your project root folder or Open terminal in your android studio.

    3. Type locale.

    You will get the response LANG="" LC_COLLATE="C" LC_CTYPE="C" LC_MESSAGES="C" LC_MONETARY="C" LC_NUMERIC="C" LC_TIME="C" LC_ALL=

    1. Convert the response above to en_US.UTF-8 by typing the command $open ~/.zshrc

    2. Copy and paste the en_US.UTF-8 encoding to it. export LANG=en_US.UTF-8 export LANGUAGE=en_US.UTF-8 export LC_ALL=en_US.UTF-8

    3. Hold Command + s (to save the .zshrc file) then after close it

    4. Type locale command again to verify your changes.

    5. Run your code flutter run. :) Happy coding!
