Pods unable to update or install - Dart/Flutter - firebase

Question

I want to implement firebase and for that I have to update the pods. However, when I type pod repo update in the console, it just does nothing... it just shows my "Updating spec repo 'trunk'" and then it shows my prompt. And if I type pod install into the console it shows:
[!] Invalid `Podfile` file: /Users/tlobry/Desktop/Flutter/Generated.xcconfig must exist. If you're running pod install manually, make sure flutter pub get is executed first.
# from /Users/tlobry/Desktop/Podfile:16
# -------------------------------------------
# unless File.exist?(generated_xcode_build_settings_path)
> raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
# end
# -------------------------------------------
this is my pubspec.yaml:
name: flash_chat
description: A new Flutter application.
version: 1.0.0+1
environment:
sdk: ">=2.1.0<3.0.0"
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^0.1.2
animated_text_kit: ^4.1.1
firebase_core: ^1.0.3
firebase_auth: ^1.0.2
cloud_firestore: ^1.0.4
dev_dependencies:
flutter_test:
sdk: flutter
flutter:
uses-material-design: true
assets:
- images/
and this is my Podfile:
# Uncomment this line to define a global platform for your project
platform :ios, '9.0'
# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'
project 'Runner', {
'Debug' => :debug,
'Profile' => :release,
'Release' => :release,
}
def flutter_root
generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
unless File.exist?(generated_xcode_build_settings_path)
raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
end
File.foreach(generated_xcode_build_settings_path) do |line|
matches = line.match(/FLUTTER_ROOT\=(.*)/)
return matches[1].strip if matches
end
raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end
require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)
flutter_ios_podfile_setup
target 'Runner' do
use_frameworks!
use_modular_headers!
flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end
post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
end
end

Answer 1

This is what I've tried in the past to fix Pod install issues:
Remove podfile.lock from the ios folder
rm Podfile.lock
Run pod install again
You may also try changing your Podfile to
platform :ios, '10.0'
