I created a new flutter project from scratch, added the necessary packages to the pubspec.yaml file and ran the flutter pub get and then pod install command, but I get this error. I get this error both in my old projects and in my new projects.
An error occurred while processing the post-install hook of the Podfile.undefined local variable or method `config' for #<Pod::Podfile:0x00007fb1da9d7bd0>/Users/m/Documents/MobileProjects/projectOne/ios/Podfile:43:in `block (3 levels) in from_ruby'/Users/m/Documents/MobileProjects/projectOne/ios/Podfile:41:in `each'/Users/m/Documents/MobileProjects/projectOne/ios/Podfile:41:in `block (2 levels) in from_ruby'/Library/Ruby/Gems/2.6.0/gems/cocoapods-core-1.15.2/lib/cocoapods-core/podfile.rb:196:in `post_install!'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/installer.rb:1013:in `run_podfile_post_install_hook'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/installer.rb:1001:in `block in run_podfile_post_install_hooks'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/user_interface.rb:149:in `message'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/installer.rb:1000:in `run_podfile_post_install_hooks'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/installer.rb:337:in `block (2 levels) in create_and_save_projects'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/installer/xcode/pods_project_generator/pods_project_writer.rb:61:in `write!'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/installer.rb:336:in `block in create_and_save_projects'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/user_interface.rb:64:in `section'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/installer.rb:315:in `create_and_save_projects'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/installer.rb:307:in `generate_pods_project'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/installer.rb:183:in `integrate'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/installer.rb:170:in `install!'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/command/install.rb:52:in `run'/Library/Ruby/Gems/2.6.0/gems/claide-1.0.3/lib/claide/command.rb:334:in `run'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/lib/cocoapods/command.rb:52:in `run'/Library/Ruby/Gems/2.6.0/gems/cocoapods-1.15.2/bin/pod:55:in `<top (required)>'/usr/local/bin/pod:23:in `load'/usr/local/bin/pod:23:in `<main>'My podfile is like this.
