Conflicts with FlutterFire and native GeoFire plugin on iOS

I've got my app working with the Firebase RTDB but want to experiment with Firestore so I have followed the instructions and installed the 'firebase_firestore' plugin.
When I run my app now I get the following error:
Resolving dependencies of `Podfile`
[!] Unable to satisfy the following requirements:
- `Firebase/Firestore` required by `firebase_firestore (0.0.1)`
Specs satisfying the `Firebase/Firestore` dependency were found, but they required a higher minimum deployment target.
I've tried specifying platform :ios, '9.0' and also 10.0in my Podfile but that didn't make any difference. All other pods install fine.
Here's the entire Cocoapods run log: https://pastebin.com/raw/SBz8Bqgf
My Podfile looks like this (standard Flutter Podfile):
# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'
if ENV['FLUTTER_FRAMEWORK_DIR'] == nil
abort('Please set FLUTTER_FRAMEWORK_DIR to the directory containing Flutter.framework')
end
target 'Runner' do
# Pods for Runner
# Flutter Pods
pod 'Flutter', :path => ENV['FLUTTER_FRAMEWORK_DIR']
if File.exists? '../.flutter-plugins'
flutter_root = File.expand_path('..')
File.foreach('../.flutter-plugins') { |line|
plugin = line.split(pattern='=')
if plugin.length == 2
name = plugin[0].strip()
path = plugin[1].strip()
resolved_path = File.expand_path("#{path}/ios", flutter_root)
pod name, :path => resolved_path
else
puts "Invalid plugin specification: #{line}"
end
}
end
end
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['ENABLE_BITCODE'] = 'NO'
end
end
end
Here's a link to the Podfile.lock, maybe that's more interesting. I see that it has not been updated with Firestore though, presumably because the run fails: https://pastebin.com/raw/hj2jHE76

Answer 1

In case anyone else stumbles across this issue I just wanted to expand on V. Roussel's answer (which I marked as the correct answer), since Flutter kind of abstracts away this Cocoapods process. Here's what I did to be able to run "pod repo / update":
Run pod repo update
Set the environment variable FLUTTER_FRAMEWORK_DIR to something that looks like /Users/youruser/bin/flutter/bin/cache/artifacts/engine/ios/. You can do a locate Flutter.podspec to find this directory
From YourFlutterProject/ios run pod update
After this you should be able to run your app again.

Answer 2

cloud_firestore has progressed to 0.03 by now, which should allow you to run the PODs.
in pubspec.yaml
cloud_firestore: "^0.0.3"
If that does not work from the start, add Firebase core to your podfile and run pod install.
Note: As far as I have seen, you cannot yet combine Firestore with other modules such as Firebase auth or Firebase analytics.
