Firebase Admob build fails during Archive - xcode

Question

My app in general works fine but when trying to set up for release the build fails because "Module'firebase_admob'not found"
//
// Generated file. Do not edit.
//
#import "GeneratedPluginRegistrant.h"
#if __has_include(<firebase_admob/FLTFirebaseAdMobPlugin.h>)
#import <firebase_admob/FLTFirebaseAdMobPlugin.h>
#else
#import firebase_admob;
#endif
#if __has_include(<webview_flutter/FLTWebViewFlutterPlugin.h>)
#import <webview_flutter/FLTWebViewFlutterPlugin.h>
#else
#import webview_flutter;
#endif
#implementation GeneratedPluginRegistrant
+ (void)registerWithRegistry:(NSObject<FlutterPluginRegistry>*)registry {
[FLTFirebaseAdMobPlugin registerWithRegistrar:[registry registrarForPlugin:#"FLTFirebaseAdMobPlugin"]];
[FLTWebViewFlutterPlugin registerWithRegistrar:[registry registrarForPlugin:#"FLTWebViewFlutterPlugin"]];
}
#end
I coded the app in android studio, and am following the guide for release at https://flutter.dev/docs/deployment/ios
I believe the issue may have to do with not installing the admob pod into my podfile, but I have never had to do that before. But here is my podfile anyways:
# 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 parse_KV_file(file, separator='=')
file_abs_path = File.expand_path(file)
if !File.exists? file_abs_path
return [];
end
generated_key_values = {}
skip_line_start_symbols = ["#", "/"]
File.foreach(file_abs_path) do |line|
next if skip_line_start_symbols.any? { |symbol| line =~ /^\s*#{symbol}/ }
plugin = line.split(pattern=separator)
if plugin.length == 2
podname = plugin[0].strip()
path = plugin[1].strip()
podpath = File.expand_path("#{path}", file_abs_path)
generated_key_values[podname] = podpath
else
puts "Invalid plugin specification: #{line}"
end

I had the same problem, and found the solution here: https://github.com/flutter/flutter/issues/47394
It seems like you need to open Runner.xcworkspace instead of Runner.xcodeproj when you archive.
